Java Exception Handling

1. Number Format exception

public class exception {
    public static void main(String[] args) {
try{
          int num =Integer.parseInt("Virendra");
          System.out.println(num);
        }
        catch(NumberFormatException e){
            System.out.println("Number Format Exception Please Enter Integer Value");
            }
      }
}
Output: Number Format Exception please Enter Integer Value

2. Array Index Out of Bound Exception

public class exception {
    public static void main(String[] args) {
try{
            int a[]= new int[5];
//insert a value in Array
            a[6]=24;
            System.out.println(a[4]);
          }
        catch(ArrayIndexOutOfBoundsException e){
            System.out.println("This is Array Index Out Of Bound Exception);
          }
     }
}
Output: This is Array Index Out Of Bound Exception

3. Throw an exception

public class exception {
    static void avg(){
        try {
            throw new ArithmeticException("Demo");
        }
        catch (ArithmeticException e){
            System.out.println("Exception caught");
        }
    }
    public static void main(String[] args) {
        avg();
    }
}
Output:Exception caught
