如何使用java代码计算当前周的开始日期和结束日期呢？

实现思路:
    使用Calendar对象中的相关方法即可获取当前周的开始日期和结束日期

//获取当前周的开始日期
public static Date getFirstDayOfWeek(Date date) {
          Calendar c = new GregorianCalendar();
           c.setFirstDayOfWeek(Calendar.MONDAY);
           c.setTime(date);
           c.set(Calendar.DAY_OF_WEEK, c.getFirstDayOfWeek()); // Monday
           return c.getTime();
       }
   
//获取当前周的结束日期   
 public static Date getLastDayOfWeek(Date date) {
          Calendar c = new GregorianCalendar();
          c.setFirstDayOfWeek(Calendar.MONDAY);
          c.setTime(date);
          c.set(Calendar.DAY_OF_WEEK, c.getFirstDayOfWeek() + 6); // Sunday
          return c.getTime();
      }
