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...");
    }
}

Example Output

Exception Message: / by zero
java.lang.ArithmeticException: / by zero
        at com.myjava.exceptions.MyExceptionHandle.main(MyExceptionHandle.java:12)

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
