Enumeration (improved version)

With reference to the previous post. I have try to improve the code so that enum will become extensible. The code will be broken down to 2 parts. The abstract version and the implementation

Abstract enum class

public abstract class AbstractEnum {
    private final String name;
    private static int nextOrdinal = 0;
    private final int ordinal = nextOrdinal++;
    
    protected AbstractEnum(String name){
      this.name = name; 
    }
    
    public String getName(){
      return this.name;
    }
    public int getOrdinal(){
      return this.ordinal;
    }
    
    //override equals method    
    public boolean equals(Object o){
        AbstractEnum objE =  (AbstractEnum) o;
        return ( this.ordinal == objE.getOrdinal() );
    } 
}

The implementation class for Day enum.

public class DayImpl extends AbstractEnum {

    protected DayImpl(String name) {
        super(name);
        // TODO Auto-generated constructor stub
    }
    
    //creating your enum
    public static final DayImpl Mon = new DayImpl("monday");
    public static final DayImpl Tue = new DayImpl("tuesday");
    public static final DayImpl Wed = new DayImpl("wednesday");
    public static final DayImpl Thur = new DayImpl("thursday");
    public static final DayImpl Fri = new DayImpl("friday");
    public static final DayImpl Sat = new DayImpl("saturday");
    public static final DayImpl Sun = new DayImpl("sunday");
}
