Where to download the java.util.*, java.io.* classes?
提问by Carl Persson
I managed to download files for a java game called "Robobmbo". But I have run into some problems. Most of the classes have imported other classes like java.net.URLConnection. But I have no idea where to find these files. Can anyone tell me where I can download: java.net.*, java.io.*, etcetera. ?

I downloaded Eclipse, opened it, then tried opening the class file but it failed. I searched the internet and found that you should go to preference > general editorand Class File Editoras the default. But there is no class editor in the list :(. What do I do?

The io,util etc packages are part of the core Java API and should be with your JRE.
io、util 等包是核心 Java API 的一部分，应该与您的 JRE 一起使用。

The URL class is part of the Java API - i.e. when you install Java you will see it.

Try installing Java + Eclipse, then open this file in Eclipse, right click on the classes that you can't find and then select "Definition" and it will show you where they come from.
尝试安装 Java + Eclipse，然后在 Eclipse 中打开此文件，右键单击找不到的类，然后选择“定义”，它会显示它们的来源。
However - being kind - this is a terrible question, you have downloaded Java code and don't understand the very basics of how to compile or edit it.
但是 - 善良 - 这是一个可怕的问题，您已经下载了 Java 代码并且不了解如何编译或编辑它的基础知识。
