调用Java的Calendar.getTime（）是否需要更新对象？ [英] Is calling Java's Calendar.getTime() necessary to update the object?

问题描述

我在一些java代码中发现了一条注释，声明需要调用 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.

这是代码：

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。
