In this blog, we will learn how to capture webelement screenshot using selenium. Till Selenium 3 we have an option that to take the screenshot for an entire webpage. From selenium 4 onwards they have introduced an option that to capture a webelement. Previously, using some third party libraries like Ashot, shutterbug to capture the webelemet or webpage.

Pre-requisites:

1. Add the selenium-4-alpha.jar file in your project or add the corresponding dependency is yours is a Maven project
2. in your class file, inspect the target element and store it in a webelement.
3. Now, use the regular screenshot logic method and store the value in a folder using Filehandler method.
4. Instead of driver, use the webelement reference variable to capture the screenshot of the target element instead of full webpage.

package Basics;

import java.io.File;

import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.io.FileHandler;

public class CaptureWebelementScreenshot {

public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
WebDriver driver;
System.setProperty("webdriver.chrome.driver", "E:\\Selenium-Softwares\\chromedriver.exe");
//System.setProperty("webdriver.gecko.driver", "E:\\Selenium-Softwares\\geckodriver.exe");
driver=new ChromeDriver();
driver.get("http://demo.automationtesting.in/Register.html");
Thread.sleep(3000);
WebElement element = driver.findElement(By.id("imagetrgt"));

File source = ((TakesScreenshot)element).getScreenshotAs(OutputType.FILE);
FileHandler.copy(source, new File("./screenshots/element.png"));
Thread.sleep(3000);
driver.quit();

}

}

In the below snippet, we have done the following to swap two numbers without using temp variable:

1. Create two int variables and assign them with some values. Here we have taken a=20 and b=30 respectively.
2. Here, swap operation can be done by assigning the values of variables (a and b) to one another as below and getting the latest values in those respective variables which is shown in the below code:

package Javaprograms;

public class SwapTwoNumbersWithoutTempVariable {

	public static void main(String[] args) {
		int a = 20;
		int b = 30;
		
		System.out.println("a value before swapping is:" +a);
		System.out.println("b value before swapping is:" +b);
		
		System.out.println("---------------------------------");
		a = a+b; // a=20 + b=30; now a value = 50
		b = a-b; // a=50 - b=30; now b value = 20
		a = a-b; // a=50 - b=20; now a value = 30
		
		System.out.println("a value after swapping is:" +a);
		System.out.println("b value after swapping is:" +b);
		
	}

}

Output:
--------
a value before swapping is:20
b value before swapping is:30
---------------------------------
a value after swapping is:30
b value after swapping is:20

In the below snippet, we have done the following to swap two numbers using temp variable:

1. Create two int variables and assign them with some values. Here we have taken a=20 and b=30 respectively.
2. Now take another variable and name it as Temp
3. Here, swap operation can be done by assigning the values of variables (a and b) using Temp as a Helper which is shown in the below code:

package Javaprograms;

public class SwapTwoNumbersUsingTempVariable {

	public static void main(String[] args) {
		int a= 20;
		int b= 30;
		int temp;
		System.out.println("A vlaue before swapping is " +a);
		System.out.println("B vlaue before swapping is " +b);
		System.out.println("---------------------");
		
		temp = a;
		a = b;
		a = temp;
		
		System.out.println("A vlaue after swapping is " +a);
		System.out.println("B vlaue after swapping is " +b);

	}

}

Output:
------
a value before swapping is:20
b value before swapping is:30
---------------------------------
a value after swapping is:30
b value after swapping is:20

In this blog, we will see How to Read Data From Properties File in Java. This will be asked in the most of the interview questions.

Things to Remember:

1. Mostly, the properties file is used to maintain the configurable parameters of the project.
2. Extension for this file is “.properties”
3. Properties file data will be in a Key and Value pair format.
4. whenever you’re creating a properties file, maintain the keys in unique format. Don’t use the existing key for your new value.
   • If you use the existing key again, then whenever control searches for that key it will return the last searched value. This might leads to conflicts.

#CONFIG File
username = Username
password = pass
firstname = fname

In the below snippet, we have done the following to Read Data from properties file:

1. Created a new folder under our project and created  a new properties file with some data
2. Created a object and assigned the file location of this newly created properties file using FileInputStream class.
3. Created a object for the Properties class.
4. Loaded all the properties of our file using Properties.load() method.
5. Using .getProperty() method, we can load all our data using Key as a parameter.
6. Then, it prints the corresponding value of that key.

package Javaprograms;

import java.io.FileInputStream;
import java.util.Properties;

public class ReadDataFromPropertiesFile {

	public static void main(String[] args) throws Exception {
		FileInputStream fis = new FileInputStream("E:/Selenium/SeleniumPrgrms/resources/config.properties");
		Properties prop = new Properties();
		
		prop.load(fis);
		
		String user = prop.getProperty("username");
		String pword = prop.getProperty("password");
		String fname = prop.getProperty("firstname");
		
		System.out.println(user);
		System.out.println(pword);
		System.out.println(fname);
	}

}

Output:
--------
username = Username
password = pass
firstname = fname

In the below snippet, we have done the following:

1. Created two arrays of same datatype and assigned those with some elements
2. Created a helper class with parameters  of these two arrays
3. Inside the helper class, to compare the arrays we have done the following
   • Firstly, we compared both the declared arrays length are equal or not using arrayname.length() and returned the value
   • Then, we have iterated a for loop based on array.length() and then compared the arrays index is equal or not and returned the value.
4. In the main method, we mentioned an If condition which will validate the result based on the returned value.

package Javaprograms;

public class CompareArraysWithoutInBuiltFunctions {

	public static void main(String[] args) {
		String a[] = {"apple","bat","cat"};
		String b[] = {"apple","bat","catt"};
		
		if(arraysCompareCheck(a, b)){
			System.out.println("Both arrays are equal");
		}
		else
		{
			System.out.println("Both arrays are not equal");
		}
		
	}
		public static boolean arraysCompareCheck(String a[], String b[]){
			if(a.length!=b.length){
				return false;
			}
			else
			{
				for(int i=0;i<a.length;i++)
				{
					if(a[i]!=b[i])
					{
						return false;
					}	
				}			
			}
			return true;		
		}
	}

Output:
--------
Both arrays are not equal

Here, It’s better to use the Object class as a parameter as it is the super class which can inherit all the datatypes and supports whatever the array’s datatype is.

Below is the snippet which uses the Object class as a parameter:

If you’re using an integer array with an object class parameter, Make sure to use the derived datatype Integer instead of Int

package Javaprograms;

public class CompareArraysWithoutInBuiltFunctions {

	public static void main(String[] args) {
		//String a[] = {"apple","bat","cat"};
		//String b[] = {"apple","bat","catt"};
		
		Integer a[] = {1,2,19};
		Integer b[] = {1,2,19};
		
		if(arraysCompareCheck(a, b)){
			System.out.println("Both arrays are equal");
		}
		else
		{
			System.out.println("Both arrays are not equal");
		}
		
	}
		public static boolean arraysCompareCheck(Object a[], Object b[]){
			if(a.length!=b.length){
				return false;
			}
			else
			{
				for(int i=0;i<a.length;i++)
				{
					if(a[i]!=b[i])
					{
						return false;
					}	
				}			
			}
			return true;		
		}
	}

Output:
-------
Both Arrays are equal

The post How to Compare Two Arrays in Java without built-in functions appeared first on Selenium Webdriver Appium Complete Tutorial.

In this blog, we will learn how to compare two arrays in Java using built-in functions. This will be asked in the most of the interviews. This can be implemented in the below way:

In the below snippet, we have done the following:

1. Created two arrays and assigned some elements in it.
2. Using built-in function Arrays.equals method we can compare our two arrays and validate them accordingly.
3. Here, we have declared the two arrays differently, one with 3 elements and the other array with 4 elements
4. Validating them using If statement and the built-in function as mentioned above

package Javaprograms;

import java.util.Arrays;

public class CompareArrays {

	public static void main(String[] args) {
		int a[] = {1,3,5};
		int b[] = {1,3,4,5};
		
		if(Arrays.equals(a, b))
		{
			System.out.println("Both the Arrays are EQUAL");
		}
		else
		{
			System.out.println("Both the Arrays are not EQUAL");
		}
	}

}

Output:
-------
Both the Arrays are not EQUAL

In the below snippet, we have done the following:

1. using the same above arrays, But in this instance we have used the equal elements and equal values in their indices of those arrays to see the result as Equal.

package Javaprograms;

import java.util.Arrays;

public class CompareArrays {

	public static void main(String[] args) {
		int a[] = {1,3,5};
		int b[] = {1,3,5};
		
		if(Arrays.equals(a, b))
		{
			System.out.println("Both the Arrays are EQUAL");
		}
		else
		{
			System.out.println("Both the Arrays are not EQUAL");
		}
	}

}

Output:
-------
Both the Arrays are EQUAL

In this blog, we will learn how to remove whitespaces from a string in Java. This will be asked in the most of the interviews. This can be implemented in three different ways listed below:

1. Convert String into character array and use for loop
2. For loop with charAt() method
3. Using replaceAll() method

Method 1:

Convert String into Character array and use for loop

In the below snippet we have done the following

• Created a string and assigned it with some value (includes whitespaces)
• Created a character array and converted the string into the array by using .toCharArray() method
• Created another empty string to store the output string
• By using char.length() method we’ve iterated for loop
• Used a If statement with a condition that to store only the values which are of not a period(whitespace) type.

public class RemoveWhitespacesString {

	public static void main(String[] args) {
		
		String str = "Java is a programming language";
		char ch [] = str.toCharArray();
		String str2 = "";
		for(int i=0; i<ch.length; i++)
		{
			if(ch[i]!=' ')
			{
				str2 = str2 + ch[i];
			}
		}
		
		System.out.println(str2);
	}
}

Output:
-------

Method 2:

Convert String into Character array and use for loop with CharAt() method

In the below snippet we have done the following

• Created a string and assigned it with some value (includes whitespaces)
• Created a character array and converted the string into the array by using .toCharArray() method
• Created another empty string to store the output string
• By using char.length() method we’ve iterated for loop
• Used a If statement with a condition that to store only the values which are of not a period(whitespace) type.
• Stored all the values into output string using charAt() method

public class RemoveWhitespacesString {

	public static void main(String[] args) {
		
		String str = "Java is a programming language";
		char ch [] = str.toCharArray();	
		String str3="";
		for(int i=0; i<ch.length; i++)
		{
			if(ch[i]!=' ')
			{
				str3 = str3 + str.charAt(i);
			}
			
		}
		System.out.println(str3);
		
	}
	
}

Output:
-------
Javaisaprogramminglanguage

Method 3:

Using replaceAll() method:

In the below snippet, we have done the following:

• Created a string and assigned it with some value (includes whitespaces)
• Created another string to store the output value
• Using replaceAll() method with a regular expression which is a built-in method of string class we stored the value into the output string

public class RemoveWhitespacesString {

	public static void main(String[] args) {
		
		String str = "Java is a programming language";
		String str4=str.replaceAll(" ", "");
		System.out.println(str4);
	}
	
}

In the below snippet, we have done the following:

1. Created the below variables of int type
   • Number (assigned it with some value)
   • Sum (assigned it with some value)
   • Reminder
2. By using while loop until the number value is greater than 0. we have done the below:
   • Performed modular division of the number and stored the result in the reminder
   • Stored the reminder value in the Sum
   • Performed Division operation of the number and stored the result in the Number

public class SumOfDigitsInANumber {

	public static void main(String[] args) {
	
		int number=2587, reminder, sum = 0;
		
		while(number>0)
		{
			reminder = number % 10;
			sum = sum + reminder;
			number = number / 10;
		}
		System.out.println("The sum of digits in a given number is:" +sum);
	}

}

Output:
-------
The sum of digits in a given number is:22

1. Convert String into Character Array and use For loop
2. For loop with CharAt() method
3. Using StringBuffer class
4. Using StringBuilder class

Method 1:

Convert String into Character Array and use For loop

In the below snippet, we have done the following:

• Creating a new string and assigning a custom string value to it
• Converting this string to character array using toCharArray() method
• Calculating the length of character array and assigning it to a int variable.
• Using for loop, we will iterate this to print the string in reverse

public class StringReverseDemo {

	public static void main(String[] args) {

		String inputstring = "Krishna";
		char[] chars = inputstring.toCharArray();
		int length = chars.length;
		
		for (int i = length-1; i >=0; i--) {
			System.out.print(chars[i]);
			
		}

	}

}

Method 2:

Convert String into Character Array and use For loop

In the below snippet, we have done the following:

• Creating a new string and assigning a custom string value to it
• Converting this string to character array using toCharArray() method
• Calculating the length of character array and assigning it to a int variable.
• Creating an another new string to concat the values to a brand new string
• Using charAt() method, we will iterate this for loop to print the string in reverse and concat it to the newly created string

public class StringReverseDemo {

	public static void main(String[] args) {
		
		String inputstring = "Krishna";
		String revword = "";
		char[] chars = inputstring.toCharArray();
		int length = chars.length;
		
		for (int i = length-1; i >=0; i--) {
			revword = revword+inputstring.charAt(i);
		}
		System.out.println(revword);

	}

}

Method 3:

Using StringBuffer class

We can use StringBuffer class to reverse a string value with help of its inbuilt methods directly as below:

public class StringReverseDemo {

	public static void main(String[] args) {
		
		String inputstring = "Krishna";

		StringBuffer stringbuffer = new StringBuffer(inputstring);
		System.out.println(stringbuffer.reverse());
		
	}

}

Method 4:

Using StringBuilder class

We can use StringBuilder class to reverse a string value with help of its inbuilt methods directly as below:

public class StringReverseDemo {

	public static void main(String[] args) {
		
		String inputstring = "Krishna";

		StringBuilder stringbuilder = new StringBuilder(inputstring);
		System.out.println(stringbuilder.reverse());
		
	}

}

Write data in excel using column number in C#, We will discuss about how to write data in excel using column number in C#. Usually we will use the excel sheet to maintain the test data. We might get doubt that why we need to put the test data/results in excel. If an application feed so much of data to be need to test; then we will manage those data using external sources like text file, xml file and excel file etc…. Among these; Excel is very user friendly that we can organize the data very easily and we can read and write the data how we want. So, we mostly use excel to maintain the test data and results.

So, if you want to write huge number of test data in excel sheet to feed to the application then we need to know how many rows and columns are there in the excel. If you know exact information about the test data then only we can get the information from the excel in proper way. In this blog we will use to write data in excel using column number in C#. To do this, we need to create a console application in Visual studio and Install Microsoft.Office.Interop.Excel Nuget package.

For this we need to have the below pre-requisites:

1. Create a Console Application in Visual Studio
2. Install Microsoft.Office.Interop.Excel Nuget Package by following below steps
   • Under your Console Application, Right Click on reference, Click on Manage Nuget Package 
   • Go to Browse
   • Under Browse search for “Microsoft.Office.Interop.Excel” 
   • click on “Microsoft.Office.Interop.Excel” and then Click Install
   • Make sure that your package got installed and appears under References folder under your Console App.

What is Microsoft.Office.Interop.Excel Nuget package?

By using this Nuget package we can interact with the excel like reading data from the Excel or writing data to the excel.

To Interact with our Nuget, we need to add the below using statement:

Using xl = Microsoft.Office.Interop.Excel;

Below are the classes will use to write the column number:

1. ExcelApiTest
2. CheckExcel

Below are the Interfaces will use to Set the cell data using Microsoft.Interop.Excel package:

1. Xl.Application
2. Xl.Workbooks
3. Xl.Workbook

Below collection is needed to create a Hash table:

1. Using System.Collections

Below Constructors are called to Interact with the User defined Excel sheet:

1. ExcelApiTest

Below are the Methods will use to set the cell data using column number:

1. OpenExcel() //Establish the connection
2. CloseExcel()//Closes all the connections
3. SetCellData()

Following is the code, we have used some Interfaces and methods to create connections, setting the cell data using column number and closing the connections.

using System;
using System.Collections;
using System.Runtime.InteropServices;
using xl = Microsoft.Office.Interop.Excel;

namespace CSharpPractice
{
    class ExcelApiTest
    {
        xl.Application xlApp = null;
        xl.Workbooks workbooks = null;
        xl.Workbook workbook = null;
        Hashtable sheets;
        public string xlFilePath;

        public ExcelApiTest(string xlFilePath)
        {
            this.xlFilePath = xlFilePath;
        }

        public void OpenExcel()
        {
            xlApp = new xl.Application();
            workbooks = xlApp.Workbooks;
            workbook = workbooks.Open(xlFilePath);
            sheets = new Hashtable();
            int count = 1;
            // Storing worksheet names in Hashtable.
            foreach (xl.Worksheet sheet in workbook.Sheets)
            {
                sheets[count] = sheet.Name;
                count++;
            }
        }

        public void CloseExcel()
        {
            workbook.Close(false, xlFilePath, null); // Close the connection to workbook
            Marshal.FinalReleaseComObject(workbook); // Release unmanaged object references.
            workbook = null;

            workbooks.Close();
            Marshal.FinalReleaseComObject(workbooks);
            workbooks = null;

            xlApp.Quit();
            Marshal.FinalReleaseComObject(xlApp);
            xlApp = null;
        }

        public bool SetCellData(string sheetName, int colNumber, int rowNumber, string value)
        {
            OpenExcel();

            int sheetValue = 0;

            try
            {
                if (sheets.ContainsValue(sheetName))
                {
                    foreach (DictionaryEntry sheet in sheets)
                    {
                        if (sheet.Value.Equals(sheetName))
                        {
                            sheetValue = (int)sheet.Key;
                        }
                    }

                    xl.Worksheet worksheet = null;
                    worksheet = workbook.Worksheets[sheetValue] as xl.Worksheet;
                    xl.Range range = worksheet.UsedRange;

                    range.Cells[rowNumber, colNumber] = value;

                    workbook.Save();

                    Marshal.FinalReleaseComObject(worksheet);
                    worksheet = null;
                    CloseExcel();
                }
            }
            catch (Exception ex)
            {
                return false;
            }
            return true;
        }
}

Below is a sample program which will call the methods from the above program to set the cell data using column number from any excel sheet.

using System;

namespace CSharpPractice
{
    class CheckExcel
    {
        static void Main(string[] args)
        {
            string xlFilePath = "D:/ExcelFiles/TestData.xlsx";

            ExcelApiTest eat = new ExcelApiTest(xlFilePath);

            eat.SetCellData("Credentials", 5, 5,"FAIL");

        }

    }
}
