当我使用以下代码时，Date对象错误。
Date date = new Date(day.getYear(), day.getMonth(), day.getDay());
谁能告诉我如何从年、月、日的值中获取日期对象？
您可以使用Calendar类来实现这一点。
public static void main(String[] args) throws Exception {
Date date = new Date (115, 7, 5);
System.out.println("date = " + date);
Calendar calendar = GregorianCalendar.getInstance();
calendar.set(Calendar.DAY_OF_MONTH, 5);
calendar.set(Calendar.MONTH, 7);
calendar.set(Calendar.YEAR, 2015);
calendar.set(Calendar.MILLISECOND, 0);
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.HOUR_OF_DAY, 0);
date = calendar.getTime();
System.out.println("calendar = " + date);
// or create directly a new clanedar instance
// thanks Tom to mention this
calendar = new GregorianCalendar(2015, 7, 5);
date = calendar.getTime();
System.out.println("calendar = " + date);
}
output
date = Wed Aug 05 00:00:00 CEST 2015
calendar = Wed Aug 05 00:00:00 CEST 2015
calendar = Wed Aug 05 00:00:00 CEST 2015
