Why is Eclipse asking to declare strictfp inside enum

Question

I was trying out enum type in Java. When I write the below class,

public class EnumExample {
  public enum Day {
    private String mood;
    MONDAY, TUESDAY, WEDNESDAY;
    Day(String mood) {

    }
    Day() {

    }
  }
 }

Compiler says: Syntax error on token String, strictfp expected.
I do know what's strictfp but would it come here?

Answer 1

The enum constants must be first in the enum definition, above the private variable.

Java requires that the constants be defined first, prior to any fields or methods.

Try:

public enum Day {
    MONDAY, TUESDAY, WEDNESDAY;
    private String mood;
    Day(String mood) {

    }
    Day() {

    }
  }

Answer 2

You have maybe forgotten to add semicolon after last enum constant.

public enum Element {
    FIRE,
    WATER,
    AIR,
    EARTH,  // <-- here is the problem

    private String message = "Wake up, Neo";
}

Answer 3

You can't define instance variable before enum elements/attributes.

public enum Day {
   
    MONDAY("sad"), TUESDAY("good"), WEDNESDAY("fresh");
    private String mood;
    Day(String mood) {
    this.mood = mood;
 }
