我正在使用日期sql,并且getDay()返回此日期表示的星期几。返回值(0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday

//type of dateStart and dateEnd is  java.sql.Date
//type of DateTime is joda.time.DateTime
public static Date[][] getListPeriod(Date dateStart , Date dateEnd){
DateTime start = new DateTime(dateStart.getYear()+1900,dateStart.getMonth()+1,dateStart.getDay(), 0, 0, 0, 0);


示例:日期值开始时间:2015-07-01
并且dateStart.getDay()返回2015-07-03(3 =星期三)

我想dateStart.getDay()将此值设为1

最佳答案

使用new DateTime(dateStart.getTime())怎么样?

要从java.sql.Date获取(每月的)日期,必须使用getDate。此方法继承自java.util.Date并已弃用。从日期获取零件的正确方法是使用Calendar
