java.awt包中提供了GUI设计所使用的类和接口，如下图：
java的图形用户界面最基本的组成部分是component，组件不能独立显示的，必须将组件放在一个容器中才可以。（如panel,frame)
container也是一个component的子类，因此容器也是一个组件，它具有组件的所有的性质，但它的主要功能就是容纳其它组件和容器。
layoutManager：每个容器都有一个layoutManager。如果设定了某个管理方式后，用户使用其它的布局方法如：setSize()等将被屏蔽。setLayout(null)可以关闭容器管理器。常用的容器有frame,panel,applet。容器中添加其它组件使用add()方法。
布局管理器主要包括：FlowLayout，BorderLayout，GridLayout，CardLayout，GridBagLayout
***：1.frame是一个顶级窗体，它的缺省管理器为BorderLayout.
2.panel无法单独显示，必须添加到某个容器中，它的缺省管理器为,当panel添加到某个容器后它还有自己的管理器！！
