java 多线程-实现Callable接口
重写的call方法可以有返回值,可以抛出异常 public class ThreadDownload implements Callable<Boolean> { public Boolean call() throws Exception return true; }public static void main(String[]args) throws InterruptedException,ExecutionException{ThreadDownload a=new ThreadDownload();ThreadDownload b=new ThreadDownload();ThreadDownload c=new ThreadDownload();//创建执行服务ExecutorService ser =Executors.newFixedThreadPool(3);//提交执行Future<Boolean>result1=ser.submit(a);Future<Boolean>result2=ser.submit(b);Future<Boolean>result3=ser.submit(c);//获取结果boolean r1=result1.get();boolean r2=result2.get();boolean r3=result3.get();//关闭服务:ser.shutdownNow();}} (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
