Enum with additional fields and custom constructor

Enum constructors must be either private or package default, and protected or public access modifier is not allowed. When custom constructor is declared, all elements declaration must match that constructor.

public enum Color { //Color is of type enum

 WHITE(21), BLACK(22), RED(23), YELLOW(24), BLUE(25);
private int code;

private Color(int c) {
code = c;
}
 public int getCode() {
return code;
}
