小编Mic*_*ick的帖子

我刚刚开始学习线程并且误解了它们的工作方式.

这是我的班级:

public class MyThread extends Thread {
    private static int NUM = 0;
    private int id;

    public MyThread() {
        id = NUM++;
    }

    public static void main(String[] args) {
        for (int i = 0; i < 10; i++) {
            new MyThread().start(); 
        }
    }

    public void run() {
        System.out.println(id + " started");

        try {
            Process p = Runtime.getRuntime().exec("javac -version");
            p.waitFor();
        } catch (Exception e) {
            System.out.println("Call a doc!");
        }

        System.out.println(id + " finished");
    }
}
