java内部类

定义一个测试类Test.java

public class Test {

	public static void main(String[] args) {
	   Runnable t  = new Runnable(){
		   public void run() { }
	   };
	}
	private static class StaticClassA{}
	
	private class InnerClassB{}
	
}

 
编译后得到
Test$1.class
Test$InnerClassB.class
Test$StaticClassA.class
Test.class

 分别对应Test类内部定义的内部类
