java 获取到当前系统的年份，只是当前的年份

public static String getSysYear() {
        Calendar date = Calendar.getInstance();
        String year = String.valueOf(date.get(Calendar.YEAR));
        return year;
}

public static String getCurrentYear(){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy");
        Date date = new Date();
        return sdf.format(date);
}
