Increment (). Increment (). print ();}    } Results Number=3;public class Thisdemo {      int number=0;    Thisdemo increment () {          int number=1;         this.number++;///         return this;    }    private void print () {         System.out.println ("number=" +number);    public static void Main (string[] args) {        thisdemo tt=new thisdemo ();         Tt.increment ().
