Number Format Exception

 It is child class of illegalArgumentException and it is unchecked.

It is thrown programmatically to indicate that the application has attempted to convert a string to number but the string is not format properly

Example:

public static void main(String[] args) {

      Integer integer = new Integer(“10”);

      System.out.println(integer);

      Integer integer2 = new Integer(“ten”); —–> string to number but the string is  not format properly.                     

      System.out.println(integer2);

            }}

Output:
