      if(str1.compareTo(str2) > 0){
         System.out.println("First String is Greater than Second String.");
      }else if(str1.compareTo(str2) < 0){
         System.out.println("First String is Smaller than Second String.");
      }else{
         System.out.println("Both Strings are Equal (i.e. String1 is Equal to String2)");
      }
