Java program to handle ClassNotFoundException

Java example to handle ClassNotFoundException.
Submitted by Nidhi, on April 18, 2022

Problem statement

In this program, we will handle a ClassNotFoundException using the try, catch block. The code that may generate an exception should be written in the "try" block, and the "catch" block is used to handle the exception and prevent program crashes.

Source Code

The source code to handle the ClassNotFoundException is given below. The given program is compiled and executed successfully.

// Java program to handle ClassNotFoundException

public class Main {
  public static void main(String[] args) {
    try {
      Class.forName("IncludeHelp");
    } catch (ClassNotFoundException e) {
      System.out.println("Exception: " + e);
    }

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

Output

Exception: java.lang.ClassNotFoundException: IncludeHelp
Program Finished

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" and "catch" blocks. In the "try" block, a Class not found Exception gets generated because we tried to get an instance of the class, which does not exist.

Here, we handled generated exceptions using the "catch" block and printed exception message.
