java - 在一行中设置日期

Question

根据 Java API，构造函数 Date(year, month, day) 已被弃用。我知道我可以用以下代码替换它:

Calendar myCal = Calendar.getInstance();
myCal.set(Calendar.YEAR, theYear);
myCal.set(Calendar.MONTH, theMonth);
myCal.set(Calendar.DAY_OF_MONTH, theDay);
Date theDate = myCal.getTime();

但是，我想要更短的内容来替换它(最好是一到两行)。

Answer 1

您可以使用 new GregorianCalendar(theYear, theMonth, theDay) .getTime():

public GregorianCalendar(int year, int month, int dayOfMonth)

Constructs a GregorianCalendar with the given date set in the default time zone with the default locale.
