In some situations, you want to do specific actions for a couple of values but at the same time, if the value falls in a certain range, you want further testing and additional actions. Here is an example I can think of: public class Program { public static void main(String[] args) { int result = 6; switch(result) { case 10: System.out.println("Excellent"); break; case 9: System.out.println("Very Good"); break; case 8: System.out.println("Good"); break; case 1: System.out.println("very"); case 2: System.out.println("very"); case 3: System.out.println("very"); case 4: System.out.println("very"); case 5: System.out.println("very"); case 6: System.out.println("very"); case 7: System.out.println("bad"); } } } If result is between 1 and 7, you'll get different number of "very" then "bad,"

You need a break after each case to avoid fall-through.

if u have no break then it will increase the runtime of the programme
