public String monday; public String tuesday; public String wensday; public String thursday; public String friday; public String saturday; public String sunday;

?? ? 或者你想定义成公用的变量，以为其它类来使用：public static final String monday = "1"; public static final String tuesday = "2"; public static final String wensday = "3"; public static final String thursday = "4"; public static final String friday = "5"; public static final String saturday = "6"; public static final String sunday = "7";
?
?
??? 如果你已经厌倦了上面的代码，那就用枚举类型实现吧，代码如下：public enum Weekday {
monday,tuesday,wensday,thursday,friday,saturday,sunday
}
?

??? 哇哦，是不是很cool，哈哈！ ………………………………..等等，为什么只有变量没有赋值呢？
