Default

    When you create string literals jvm maintain all of them in pool known as String pooling.
for exapmle,

    String s1 = "Arul"; //case 1
    String s2 = "Arul"; //case 2

    In case 1, iteral s1 is created newly and kept in the pool. But in case 2, literal s2 refer the s1, it will not create new one instead.

      if(s1 == s2) System.out.println("equal"); //Prints equal.

      String n1 = new String("Arul");
      String n2 = new String("Arul");
      if(n1 == n2) System.out.println("equlal"); //No output.
