是否需要调用 Java 的 Calendar.getTime() 来更新对象?

我在一些 java 代码中看到一条注释,指出需要调用 getTime() 来更新 Calendar 对象.这是真的?我找不到任何说这是必要的.

I came across a comment in some java code that states that getTime() needs to be called to update the Calendar object. Is this true? I cannot find anything that says that this is necessary.

代码如下:

Calendar cal = new GregorianCalendar();
cal.setFirstDayOfWeek(Calendar.SUNDAY);
cal.set(2009, 9 - 1, 10, 2, 30);
// Get Time needs to be called to update the Calendar object
cal.getTime();

推荐答案

不,这不是真的.
