Java program to implement finally block when the exception is not caught

Java example to implement finally block when the exception is not caught.
Submitted by Nidhi, on April 19, 2022

Problem statement

In this program, we will use finally block with a try, catch. Here we will not catch generated exceptions.

The finally block is a block that executes whether an exception rise or not and whether the exception is handled or not.

Source Code

The source code to implement the finally block when an exception is not caught is given below. The given program is compiled and executed successfully.

// Java program to implement finally block 
// when the exception is not caught

public class Main {
  public static void main(String[] args) {
    try {
      int a = 10, b = 0, c = 0;

      c = a / b;

      System.out.println("Division is: " + c);

    } catch (NullPointerException e) {
      System.out.println("Exception: " + e);
    } finally {
      System.out.println("The finally block executed");
    }

    System.out.println("Program Finished");
  }
}

Output

The finally block executed
Exception in thread "main" java.lang.ArithmeticException: / by zero
        at Main.main(Main.java:9)

Explanation

In the above program, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

Here, we created try, catch, and finally blocks. In the try block, it generates a divide by zero exception which is not caught by the catch block.  But the finally block executes whether an exception rise or not and whether the exception is handled or not.
