转：Eclipse 各种小图标的含义

Eclipse 各种小图标的含义，记录一下。

Eclipse的Package Explorer和Outline中用图标表示了很多内容，其实能看懂这些图标在编程中也是很有用的。

      绿色的小圆表示公有类型：如果是实心的就是函数（），如果是圈就表示是变量（）。
      红色的矩形表示私有类型：如果是实心的就是函数（），如果是空心就表示是变量（）。
      保护类与保护函数用的是黄色的菱形：大菱形表示是函数（），小菱形表示是变量（）。

如果有一个向上的小三角就表示这是个函数，并且会抛出异常。（）
如果有一个类似表型的圆圈就表示该变量或函数是synchronized（线程同步）。（）

      如果小图标出现一个C，就表示这是构造函数（）。
      如果小图标出现一个A，就表示这是抽象函数（abstract）（）。
      如果小图标出现一个F，就表示这是抽象函数（final）。（）
      如果小图标出现一个S，就表示这是静态函数（static）（）

类的图标是一个大C，表示一个类（），如果带一个放音键似的三角，那就代表这个类是存在main函数的类（）
