[游戏开发]学习博客：Calendar类

Calendar提供了获取、设置各种日历字段的方法

构造方法：protected Calendar(); 由于修饰符为protected，无法直接创建对象，但可以使用静态方法

static Calendar getInstance();

import java.util.Calendar;

public class TestCalendar {
    public static void main(String[] args) {

        Calendar calendar = Calendar.getInstance();
        //年
        int year = calendar.get(calendar.YEAR);
        //月  范围0~11
        int month = calendar.get(calendar.MONTH);
        //日
        int day = calendar.get(calendar.DAY_OF_MONTH);
        //小时
        int hour = calendar.get(calendar.HOUR);
        //分钟
        int minute = calendar.get(calendar.MINUTE);
        //秒
        int second = calendar.get(calendar.SECOND);

        System.out.println(year + "年" + (month+1) + "月" + day + "日" + hour + "时" + minute + "分" + second + "秒");

        //修改时间
        Calendar calendar2 = Calendar.getInstance();
        calendar2.set(Calendar.DAY_OF_MONTH,1);     //修改至1号
        System.out.println(calendar2.getTime().toLocaleString());

        //add方法修改时间
        calendar2.add(calendar2.HOUR,2);    //快进2小时
        System.out.println(calendar2.getTime().toLocaleString());

        //获取当前属性最大最小值
        int max = calendar2.getActualMaximum(Calendar.DAY_OF_MONTH);
        int min = calendar2.getActualMinimum(Calendar.DAY_OF_MONTH);
        System.out.println(max);
        System.out.println(min);

    }
}
