似乎只检查月份就可以了：
private static final String seasons[] = { "Winter", "Winter", "Spring", "Spring", "Summer", "Summer", "Summer", "Summer", "Fall", "Fall", "Winter", "Winter"};public String getSeason( Date date ) { return seasons[ date.getMonth() ];}// As stated above, getMonth() is deprecated, but if you start with a Date, // you'd have to convert to Calendar before continuing with new Java, // and that's not fast.
