Comparing enum and Long

Question

I've got a simple enum and in my main() i want to compare this enum to Long variable, but I have an error HelloWorld.java:15: error: incomparable types: Long and myEnum System.out.println(x == myEnum.ENUM_A);. How to repair it and compare it correctly?

public class HelloWorld{
    public enum myEnum {
            ENUM_A(1), 
            ENUM_B(2), 
            ENUM_C(3);
     
            int n;
     
            private myEnum(int n) {
                this.n = n;
            }
     }
     public static void main(String []args){
        Long x = 1L;
        System.out.println(x == myEnum.ENUM_A);
     }
}

Answer 1

You need to add a getN() to your enum:

public enum myEnum {
  ENUM_A(1),
  ENUM_B(2),
  ENUM_C(3);

  int n;

  private myEnum(int n) {
     this.n = n;
  }

  public int getN() {
     return n;
  }
}

and then in your main do System.out.println(x == myEnum.ENUM_A.getN());

If you need to compare any value, in your case a long with your enum, you will need to get the value of the enum.

Another alternative to the == is Objects from the java.util

Objects.equals(value1, value2)
