public abstract class WeekDay{

   public static final WeekDay MON = new WeekDay(){

   };
   public abstract WeekDay nextDay();
   public String toString(){
    return this == SUN? "SUN":"MON";
   }
}
这是用普通类模拟枚举原理，我是想问toString中这个return语句怎么写完，我不会，求请教

虽然是沙发,但是不懂

用eclipse 生成 toString

public String toString()
{
        return "WeekDay [nextDay()=" + nextDay() + ", getClass()=" + getClass()
                        + ", hashCode()=" + hashCode() + ", toString()=" + super.toString()
                        + "]";
}
