how to add two values in switch cases java code example

Example 1: java switch multiple values

switch (num) {
            case 5:
            case 2:
            case 3:
                System.out.println("5,2,3");
                break;
            case 4:
            case 6:
                System.out.println("4,6");
                break;
            case 1:
                System.out.println("1");
                break;
            default:
                System.out.println("Inavlid number");
                break;
        }

Example 2: Java switch with multiple cases

// Java switch with multiple cases
public class SwitchMultipleCase
{
   public static void main(String[] args)
   {
      System.out.println(multipleCase("one"));
      System.out.println(multipleCase("two"));
   }
   static String multipleCase(final String number)
   {
      String str = null;
      switch(number)
      {
         case("one"):
         case("three"):
         case("five"):
             str = "odd numbers";
         break;

         case("two"):
         case("four"):
         case("six"):
             str = "even numbers";
         break;
         default:
             str = "please enter valid input";
      }
      return str;
   }
}
