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 作者: 飞飞飞丨 时间: 2015-7-26 18:00

用eclipse 生成 toString作者: 谢永烽 时间: 2015-7-26 18:08
public String toString()
{
return "WeekDay [nextDay()=" + nextDay() + ", getClass()=" + getClass()
+ ", hashCode()=" + hashCode() + ", toString()=" + super.toString()
+ "]";
