Level.java
public enum Level
{
    HIGH(3), // calls constructor with value 3
    MEDIUM(2), // calls constructor with value 2
    LOW(1);// calls constructor with value 1

    private final int levelCode;

    private Level(int levelCode)
    {
        this.levelCode = levelCode;
    }

    public int getLevelCode()
    {
        return this.levelCode;
    }
}
EnumDemo.java
public class EnumDemo
{

    public static void main(String[] args)
    {
    
        Level[] levelArray = Level.values();
        for (Level level : levelArray)
        {
            System.out.println(level + " = " + level.getLevelCode());
        }
