17.1 スレッドの例 1

複数のスレッドを生成して，それらを並行して同時に実行させる例．

/* basic/MyThread.java */
package basic;

public class MyThread0 {
    public static void main (String[] args) {
        MyThread1 myTh1 = new MyThread1();
        myTh1.start();
        Thread myTh2 = new Thread(new MyThread2());
        myTh2.start();

        final long ms = 500;
        while (true) {
            System.out.println("MyThread 0");
            try {
                Thread.sleep(ms);
            } catch (InterruptedException e) {}
        }
    }
}

/* basic/MyThread1.java */
package basic;

class MyThread1 extends Thread {
    final long ms = 1000;

    public void run() {
        while (true) {
            System.out.println("MyThread . 1");
            try {
                sleep(ms);
            } catch (InterruptedException e) {}
        }
    }
}

/* basic/MyThread2.java */
package basic;

class MyThread2 implements Runnable {
    long ms = 2000;

    public void run() {
        while (true) {
            System.out.println("MyThread . . 2");
            try {
                Thread.sleep(ms);
            } catch (InterruptedException e) {}
        }
    }
}

コンパイルと実行は次のようになる．

% java basic.MyThread0

MyThread . . 2
