You simply write if (b) . . . So, for example, change case( ii4 == 1 ): to case 1: You might want to read the tutorial on switch statements. System.out.println("Enter your choice in the following way."); System.out.println("1.rock 2.Paper 3.Scissors"); Now, use the values of 1,2 and 3 in your switch statements so you can avoid string altogether. For example, is 1*1 or true&&false faster?
