     */
    public String date2Zodica(int year) {

        return zodiacArray[year % 12];
    }

        month = month - 1;
        if (day < constellationDay[month]) {
            month = month - 1;
        }
        if (month >= 0) {
            return constellationArray[month];
        }
        // 默认魔羯
        return constellationArray[11];
    }

    /**
     * 根据出生年份得到年龄

     * @return
     */
    public int date2Age(int year) {

        Calendar c = Calendar.getInstance();
        int y = c.get(Calendar.YEAR);
        int age = y - year;

        if (age < 0) {
            age = 0;
        }
        return age;

    }

}

使用方法

String constellation = ConstellationHepler.getInstance().date2Constellation(5, 5);
        String zodica = ConstellationHepler.getInstance().date2Zodica(1990);
        int age = ConstellationHepler.getInstance().date2Age(1990);
        System.out.println(constellation);
        System.out.println(zodica);
        System.out.println(age);
