使用LocationManager获取当前日期和时间

import java.util.Calendar;

public class Main {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance();
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH) + 1; // 月份从0开始，需要加1
        int day = calendar.get(Calendar.DAY_OF_MONTH);
        int hour = calendar.get(Calendar.HOUR_OF_DAY);
        int minute = calendar.get(Calendar.MINUTE);
        int second = calendar.get(Calendar.SECOND);

        System.out.println("当前日期和时间：");
        System.out.println("年：" + year);
        System.out.println("月：" + month);
        System.out.println("日：" + day);
        System.out.println("时：" + hour);
        System.out.println("分：" + minute);
        System.out.println("秒：" + second);
    }
}
