Java启动两个线程? [英] Java starting two threads?

问题描述

我是 Java 新手.我有两个类，看起来像:

i am new to java. I have two classes that looks like:

public class hsClient implements Runnable {

  public void run() {
    while(true){
    }
  }
}

public class hsServer implements Runnable {

  public void run() {
    while(true){
    }
  }
}

如果我尝试将两个类都作为线程启动，它就不会启动第二个线程.看起来他卡在第一个.

If i try to start both classes as Thread it wont start the second thread. It looks like he stuck in the first one.

这是我的主要课程:

public static void main(String[] args) throws IOException {
        hsClient client = new hsClient();
        Thread tClient = new Thread(client);
        tClient.run();
        System.out.println("Start Client");
        hsServer server = new hsServer();
        Thread tServer = new Thread(server);
        tServer.run();
        System.out.println("Start Server");
}

如果我运行我的代码，它只会在控制台上打印启动客户端"而不是启动服务器"

If i run my code it only prints "Start Client" but not "Start Server" on the console

推荐答案

用 tClient.start() 和 tServer.run 替换 tClient.run()() 和 tServer.start().

调用run方法直接在当前线程中执行，而不是在新线程中执行.

Calling the run method directly executes it in the current thread instead of in a new thread.
