Java程序获取星期的开始和结束日期
首先，设置一个日期：
LocalDate date = LocalDate.of(2019, 4, 16);
现在，获取星期几的日期：
LocalDate start = date;
while (start.getDayOfWeek() != DayOfWeek.MONDAY) {
start = start.minusDays(1);
}现在，获取本周结束的日期：
LocalDate end = date;
while (end.getDayOfWeek() != DayOfWeek.SUNDAY) {
end = end.plusDays(1);
}示例
import java.time.DayOfWeek;
import java.time.LocalDate;
public class Demo {
public static void main(String[] argv) {
LocalDate date = LocalDate.of(2019, 4, 16);
System.out.println("Date = " + date);
LocalDate start = date;
while (start.getDayOfWeek() != DayOfWeek.MONDAY) {
start = start.minusDays(1);
}
System.out.println("Start of the Week = " + start);
LocalDate end = date;
while (end.getDayOfWeek() != DayOfWeek.SUNDAY) {
end = end.plusDays(1);
}
System.out.println("End of the Week = " + end);
}
}输出结果
Date = 2019-04-16 Start of the Week = 2019-04-15 End of the Week = 2019-04-21
