Java Exception Handling Examples

Exceptions can be handled by using 'try-catch' block. Try block contains the code which is under observation for exceptions. The catch block contains the remedy for the exception. If any exception occurs in the try block then the control jumps to catch block.

Java Exception Handling Sample Code

Code:
package com.myjava.exceptions;

public class MyExceptionHandle {
    public static void main(String a[]){
        try{
            for(int i=5;i>=0;i--){
                System.out.println(10/i);
            }
        } catch(Exception ex){
            System.out.println("Exception Message: "+ex.getMessage());
            ex.printStackTrace();
        }
        System.out.println("After for loop...");
    }
}
