eclipse怎么查看java源代码

在Eclipse中查看JDK类库的源代码

设置：

1.点 “window”- "Preferences" - "Java" - "Installed JRES"

2.此时"Installed JRES"右边是列表窗格，列出了系统中的 JRE 环境，选择你的JRE，然后点边上的 "Edit..."， 会出现一个窗口(Edit JRE)

3.选中rt.jar文件的这一项：“c:\program files\java\jre_1.5.0_06\lib\rt.jar” 

点 左边的“+” 号展开它

4.展开后，可以看到“Source Attachment:(none)”，点这一项，点右边的按钮“Source Attachment...”, 选择你的JDK目录下的 “src.zip”文件

5.一路点"ok",结束。

dt.jar是关于运行环境的类库,主要是swing的包 

tools.jar是关于一些工具的类库 

rt.jar包含了jdk的基础类库，也就是你在java doc里面看到的所有的类的class文件

使用：

可以在 Java 源代码编辑器或代码片段编辑测试窗中选择类型、方法或字段的名称，然后对元素的定义打开编辑器。

在 Java 编辑器中，选择类型、方法或字段的名称。您也可以仅仅在名称中单击一次。 

执行下列其中一项操作： 

1.从菜单栏中，选择浏览 打开声明 

2.从编辑器的弹出菜单中，选择打开声明 

3.按 F3 键，如下图
