Finally Block in Java

Here are the implementation of Finally block in java language:

Java

// Java code to display the use of finally block in
// exception handling

import java.io.*;

public class ExceptionHandlingExample {
    public static void main(String[] args)
    {
        try {
            // Code that may cause an exception
            int result = divide(
                10, 0); // Attempting to divide by zero
            System.out.println(
                "Result: "
                + result); // This line won't be executed
        }
        catch (ArithmeticException e) {
            // Handling the exception
            System.out.println("An error occurred: "
                               + e.getMessage());
        }
        finally {
            // finally block
            System.out.println(
                "\nFinally block executed, performing cleanup tasks.");
        }
    }

    public static int divide(int num1, int num2)
    {
        return num1 / num2;
    }
}

Output

An error occurred: / by zero

Finally block executed, performing cleanup tasks.

Finally Block in Programming

The finally block in programming, commonly used in languages like Java and C#, is a block of code that is executed regardless of whether an exception is thrown or not. It is typically used in conjunction with a try-catch block to ensure certain cleanup or finalization tasks are performed, such as closing resources like files or database connections.
