Eclipse-编译和执行程序 [英] Eclipse - Compiling & executing program

问题描述

过去，我曾使用JCreator开发我的Java应用程序.我想尝试Eclipse并查看其IDE.

在JCreator上，我可以打开一个Java文件并在命令提示符下运行它.在Eclipse上，如果不先创建项目，创建新的Java类，然后从文件中复制并粘贴代码，就无法找到如何编译和运行别人编写的Java文件的方法.

我什至不知道如何将Java文件导入项目.

所以我的问题:
1.如何在不首先创建Java项目的情况下打开，编译和运行Java文件.
2.如何将Java文件导入到已有的项目中.
3.如何直接在Eclipse中而不是在Eclipse的控制台上在命令提示符下运行程序(更新:更加清楚).

谢谢.

3/由于您希望它直接从eclipse运行，因此请用作

1/ Do not forget scrapbook page (also presented here)

In theory, you could copy a class in it, but since that class is actually encapsulated into a "main invisible" class, as an inner class, it would not support any static methods in it.

However, for a quick chunk of code, it does the trick just fine.

(from this Eclipse tutorial)

3/ Since you want it run directly from eclipse, use as indicated in this thread, an External tool

That External Tool would run C:\WINDOWS\system32\cmd.exe with working directory ${container_loc}
