How to Compare strings in java [duplicate]

Answer 1

How I think you can approach this problem is by specify a set of pre-defined input parameter for the user to choose from then respond accordingly based on there choice e.g:

 System.out.println ("Enter you mood: [1 = happy,2 = sad,3 = confused]");
 int input = new Scanner(System.in).nextInt ();

 switch (input)
 {
   case 1:  System.out.println ("I am happy");break;
   case 2:  System.out.println ("I am sad");break;
   default: System.out.println ("I don't recognize your mood");
 }
