如果我有 Eclipse 是否需要安装 Java SDK [英] Do I need to install Java SDK if I have eclipse

问题描述

我已经使用 Eclipse 2 周了，所有程序都运行良好.

I have been using Eclipse for 2 weeks and all programs are working fine.

但是我发现我并没有专门安装Java SDK.

But I have realized that I have not specifically installed Java SDK.

是正常的还是Eclipse有自己的编译器?

Is it normal or does Eclipse have its own compiler?

我需要测试 JDBC MySQL 连接器，现在我不知道从哪里复制该文件，因为在我的:

I need to test the JDBC MySQL connector and now I don't know where to copy that file because in my:

C:/programfiles/java

我只有一个目录是 JRE 6.

I have only one directory that is JRE 6.

推荐答案

是的，你说得对.Eclipse 有自己的编译器，因此如果您使用 Eclipse，则不需要 JDK.

Yes you're right. Eclipse has its own compiler so you don't need JDK if you are working with Eclipse.

有些案例/插件仅适用于 JDK，例如 Maven.因此，如果您打算使用 Maven(从控制台或从 Eclipse)，您将需要 下载JDK.

There is some cases/plugins that are only working with JDK such as Maven. So if you are planning to use Maven (either from Console or from Eclipse) you will need to download JDK.

对于您的 mysql 连接器，通常的做法是将 jar 复制到您的项目目录(或者可能在 lib 目录下)并将其添加到构建路径中.jar 位于该位置后，您可以刷新工作区，单击鼠标右键，然后选择构建路径，添加到构建路径.

For your mysql connector, a common practice is to copy the jar to your project directory (or maybe under lib directory) and add it to the build path. Once the jar is in the location, you can refresh the workspace, right click, and select Build Path, add to Build Path.
