Java示例使用Enum-Switch

public class MainClass {

   enum Choice { Choice1, Choice2, Choice3 }

   public static void main(String[] args) {

      Choice ch = Choice.Choice1;



      switch(ch) {

         case Choice1:

            System.out.println("Choice1 selected");

            break;

         case Choice2:

            System.out.println("Choice2 selected");

            break;

         case Choice3:

            System.out.println("Choice3 selected");

             break;

      }

   }

}
