经典Java一小例

1.普通类

public class Executor {

	public void execute(){
		System.out.println("Executor ---> execute");
	}
}

2.测试类

public class Test {
	public static void main(String[] args) {
		Executor executor = new Executor(){
			public void execute(){
				System.out.println("Do something...");
			}
		};
		executor.execute();
	}
}

Java回调函数实现的灵魂...
