Java判断日期是不是当天、本周、本月、本季度、本年

直接上代码

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
 
 
public class DateStatusUtil {

        return false;
    }
 
    //判断选择的日期是否是本月

        return time.after(QuarterStart) && time.before(QuarterEnd);
    }

            c.set(Calendar.DATE, 1);
            now = longSdf.parse(shortSdf.format(c.getTime()) + " 00:00:00");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return now;
    }
 
    /**
     * 当前季度的结束时间
     * @return
     */
    public static Date getCurrentQuarterEndTime() {
        Calendar cal = Calendar.getInstance();
        cal.setTime(getCurrentQuarterStartTime());
        cal.add(Calendar.MONTH, 3);
        return cal.getTime();
    }
 
	public static void main(String[] args) {
 
		try {
			System.out.println("当天:" + DateStatusUtil
					.isToday(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2021-07-15 08:23:21")));
			System.out.println("本周:" + DateStatusUtil
					.isThisWeek(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2021-07-25 08:23:21")));
			System.out.println("本月:" + DateStatusUtil
					.isThisMonth(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2021-07-15 08:23:21")));
			System.out.println("本年:" + DateStatusUtil
					.isThisYear(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2022-07-15 08:23:21")));
			System.out.println("本季度:" + DateStatusUtil
					.isThisQuarter(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2021-07-15 08:23:21")));
 
		} catch (Exception pe) {
			System.out.println(pe.getMessage());
		}
 
	}
 
}

运行后输出:

当天:true
本周:false
本月:true
本年:false
本季度:true
