package com.utcsoft.pcapps.selfservice.controller;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;public class Test {public static void main(String[] args) throws ParseException {Calendar cal = Calendar.getInstance();SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); // 获取本周一的日期System.out.println(df.format(cal.getTime()));cal.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);// 这种输出的是上个星期周日的日期，因为老外那边把周日当成第一天cal.add(Calendar.WEEK_OF_YEAR, 1);// 增加一个星期，才是我们中国人理解的本周日的日期System.out.println(df.format(cal.getTime()));}}

输出周一到周日的所有日期：

package com.utcsoft.pcapps.selfservice.controller;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.ArrayList;import java.util.Calendar;import java.util.Date;import java.util.List;public class Test {/**     * 根据日期获得所在周的日期      * @param mdate     * @return     */    @SuppressWarnings("deprecation")    public static List<Date> dateToWeek(Date mdate) {        int b = mdate.getDay();        Date fdate;        List<Date> list = new ArrayList<Date>();        Long fTime = mdate.getTime() - b * 24 * 3600000;        for (int a = 1; a <= 7; a++) {            fdate = new Date();            fdate.setTime(fTime + (a * 24 * 3600000));            list.add(a-1, fdate);        }        return list;    }public static void main(String[] args) throws ParseException {        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd EEE");//EEE代表星期几        Date currentDate = new Date();        List<Date> days = dateToWeek(currentDate);        System.out.println("今天的日期: " + sdf.format(currentDate));        for (Date date : days) {            System.out.println(sdf.format(date));        }}}
