Java: equals

I worked with this file long time back.



class equalsnotequalto
  {
    public static void main (String args[])
      {
         String s1 = "Hello";
         String s2 = new String(s1);
       
         System.out.println(s1+"equals"+s2+"->"+s1.equals(s2));
         System.out.println(s1+"=="+s2+"->"+(s1==s2));
      }
  }
