Question

Can we use enum inside a switch?

public enum Color {
  RED,BLUE,YELLOW


}


 public class Use {
  Color c = Color.BLUE;

  public void test(){
      switch(c){
      case Color.BLUE:

      }
  }
}

I am getting some error in this.

The enum constant Color.BLUE reference cannot be qualified in a case label  Use.java        line 7  Java Problem

Answer 1

case COLOR.BLUE:

    }

In the above code instead of COLOR.BLUE only write BLUE

E.G.

import java.awt.Color;

class ColorEnum {

    enum Color{BLUE,RED,YELLOW};

    public static void main(String[] args) {
        Color c = Color.BLUE;
        switch(c) {
            case BLUE:
                System.out.println("Blue!");
                break;
            case RED:
                System.out.println("Red!");
                break;
            case YELLOW:
                System.out.println("Yellow!");
                break;
            default:
                System.out.println("Logic error!");
        }
    }
}
