如何跟踪Java GUI应用程序上使用的时间？

Question

我正在为我的课程创建Java GUI Web浏览器，我想知道是否有一种方法可以测量（以秒，分钟等整数形式）访问特定URL的时间。

Answer 1

Could you use System.currentTimeMillis() upon page load completion, then passing that to a utility method (comparing the value with another call to System.currentTimeMillis()) as soon as another URL is loaded/the page is closed?

That is not an integer time that you would get with System.currentTimeMillis(); If you're dead set on an int number of seconds/minutes/etc, you can look into java.util.Date or Calendar
