How eclipse quickly finds a class

When we write a lot of classes, we need to find one of them. Or we need to refer to a class, but do not remember which package it is under, what to do?

1. Note: the eclipse version used in this experience is

Eclipse Java EE IDE for WEB developers.

Version:luna Service Release 1 (4.4.1)

Build id:20140925-1800

2. Open Eclipse Main Page, click "Navigate" menu, select "Open Type" option

3. Enter the class name, and the associated classes and their paths will be displayed synchronously below.

4, select the specified class, double-click the left mouse button

5, Note: It is best to remember to use the shortcut key ctrl+shift+t, more convenient development.
