Java通过出生日期计算星座、(生肖)

Java根据生日得出是十二星座的哪一个星座

方法一：

public static String constellation(int month, int day) {  
        String constellation = "";  
        if (month == 1 && day >= 20 || month == 2 && day <= 18) {  
         constellation = "水瓶座";  
        }  
        if (month == 2 && day >= 19 || month == 3 && day <= 20) {  
         constellation = "双鱼座";  
        }  
        if (month == 3 && day >= 21 || month == 4 && day <= 19) {  
         constellation = "白羊座";  
        }  
        if (month == 4 && day >= 20 || month == 5 && day <= 20) {  
         constellation = "金牛座";  
        }  
        if (month == 5 && day >= 21 || month == 6 && day <= 21) {  
         constellation = "双子座";  
        }  
        if (month == 6 && day >= 22 || month == 7 && day <= 22) {  
         constellation = "巨蟹座";  
        }  
        if (month == 7 && day >= 23 || month == 8 && day <= 22) {  
         constellation = "狮子座";  
        }  
        if (month == 8 && day >= 23 || month == 9 && day <= 22) {  
         constellation = "处女座";  
        }  
        if (month == 9 && day >= 23 || month == 10 && day <= 23) {  
         constellation = "天秤座";  
        }  
        if (month == 10 && day >= 24 || month == 11 && day <= 22) {  
         constellation = "天蝎座";  
        }  
        if (month == 11 && day >= 23 || month == 12 && day <= 21) {  
         constellation = "射手座";  
        }  
        if (month == 12 && day >= 22 || month == 1 && day <= 19) {  
         constellation = "摩羯座";  
        }  
        return constellation;  
       }  

方法二：

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" };  
public static String getConstellation(int month, int day) {  
    return day < dayArr[month - 1] ? constellationArr[month - 1] : constellationArr[month];  
}  

Java通过出生日期计算属相(生肖)和星座

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];
    }
}
