Java多线程技术实现异步调用机制

首先定义一个接口:

Icallback:

代码如下 :

public interface Icallback {
   void call();

}

定义该接口的实现类:

MyCallback

public class MyCallback implements Icallback {
@Override
public void call() {
System.out.println(Thread.currentThread().getName() + "异步方法执行完了！回调通知");
}

}

定义一个线程，用于执行耗时任务，并且将回调函数放入线程，等待耗时任务调用完成后回调:

Asynchronousclass:

public class Asynchronousclass implements Runnable {
private Icallback callable;


public Asynchronousclass(Icallback p) {
this.callable = p;
}


@Override
public void run() {


for (int i = 0; i < 5; i++) {
for (long k = 0; k < 1000000000; k++){

}


}
callable.call();
}

}

建立Test类:

public class Test {


public static void main(String[] args) {
Icallback t = new MyCallback();
Asynchronousclass ybc = new Asynchronousclass(t);
Thread t1 = new Thread(ybc);
t1.start();
System.out.println(Thread.currentThread().getName() + "走！吃饭去，我先去吃了，你等会自己来。");
}


}
