Enums – what about int value

• In old way (in java 1.4) any constant has an int value which can be used outside of Java public static final int STATUS_INUSE = 3;

• public enum Planet { MERCURY (3.303e+23), VENUS (4.869e+24), EARTH (5.976e+24);

• private final double mass; // in kilograms Planet(double mass) { this.mass = mass; } private double mass() { return mass; }

• }

• Planet.EARTH.mass();
