java监听事件“接口的妙用”

package com.cxc;

public interface ReturnListener {
public void success(String str);
public void failed(String str);
}

2，执行类

<pre name="code" class="java">package com.cxc;

public class Post {
private ReturnListener mReturnListener;
private String method;
public Post( String method,ReturnListener mReturnListener) {
super();
this.mReturnListener = mReturnListener;
this.method = method;
}

public void run(){
if (method.equals("cxc")) {
mReturnListener.failed(method+",调用失败！");
}else{
mReturnListener.success(method+",调用成功！");
}
}
}

package com.cxc;

public class Main {
public static void main(String[] args) {
Post post = new Post("cqxc", new ReturnListener() {

@Override
public void success(String str) {
System.out.println(str);
}

@Override
public void failed(String str) {
System.out.println(str);
}
});
post.run();
}
}
