Using Underscore in Numeric Literals Java

This is new Java feature introduced in Java 7 just to improve the readability of codes like we can use an Underscore character to separate digits in group of three,similar to how we would use a punctuation Mark like comma, or a space,as a seperatot.

For example; 

public class UnderscoreInLiteral

{

  public static void main(String args[])

  {

      int num = 1_00_00_000;

      System.out.println("Num:",num);

  

    long num1 = 1_00_00_000;

    System.out.println("Num",num1);

   }

}

Output:

10000000

10000000
