Java代码通过出生日期计算属相和星座，以后用到了就不用再百度了。。。

public class Year {    private final static int[] dayArr = new int[] { 20, 19, 21, 20, 21, 22, 23,            23, 23, 24, 23, 22 };    private final static String[] constellationArr = new String[] { "摩羯座",            "水瓶座", "双鱼座", "白羊座", "金牛座", "双子座", "巨蟹座", "狮子座", "处女座", "天秤座",            "天蝎座", "射手座", "摩羯座" };    /**     * 根据出生日期计算属相和星座     *      * @param args     */    public static void main(String[] args) {        int month = 7;        int day = 28;        System.out.println("星座为：" + getConstellation(month, day));        System.out.println("属相为:" + getYear(1994));    }    /**     * Java通过生日计算星座     *      * @param month     * @param day     * @return     */    public static String getConstellation(int month, int day) {        return day < dayArr[month - 1] ? constellationArr[month - 1]                : constellationArr[month];    }    /**     * 通过生日计算属相     *      * @param year     * @return     */    public static String getYear(int year) {        if (year < 1900) {            return "未知";        }        int start = 1900;        String[] years = new String[] { "鼠", "牛", "虎", "兔", "龙", "蛇", "马", "羊",                "猴", "鸡", "狗", "猪" };        return years[(year - start) % years.length];    }}
