ContentPane类是Container类的子类。

Container contentPane = getContentPane();
上面那句代码是一种多态的写法其中的getContentPane()是相当于new ContentPane()：

	指针类型 变量名 = 值；（C语言中）
	int a = 12；
	
	父类引用类型 对象名 = new 子类名()；
	Container contentPane = new ContentPane();

右边的new ContentPane()就已经创建了一个ContentPane类的对象存储在虚拟机中（我也不知道对象具体存在哪里），然后左边创建了一个Container类型的引用变量(contentPane)，并让它指向刚才的对象存储地址。

PS:
引用类似于C语言中的指针（但他们有什么不同我说不出来）

如有理解错误，敬请指出

关于setContentPane()和getContentPane()的应用------摘要：java_流子 Fab.19 2006-------- 我们可以在 JFrame 对象中添加 AWT 或者 Swing 组件。但是，虽然它有 add 方法，却不能直接用于添加组件，否则会抛出异常——不信就试试。造成这个现象的原因只有一个解释：JFrame 不是一个容器，它只是一个框架。那么，应该怎么添加组

是 Java Swing 库中JFrame类的一个方法。Swing 是用于创建图形用户界面（GUI）的一套工具和库。在 Swing 中，JFrame是创建窗口的基本类，它代表一个可以最大化、最小化和关闭的窗口。方法用于获取一个JFrame的内容面板（content pane）。内容面板是一个特殊的容器，它位于JFrame中，是放置组件的地方，如文本框、按钮、标签等。默认情况下，当你向JFrame添加组件时，这些组件实际上是添加到内容面板上，而不是直接添加到JFrame上。这里是如何使用。
