testnumbers.java

多线程 课堂讲解代码 很经典的

public class TestNumbers  {
  public static void main(String[] args) {
    Number number1 = new Number(1);
    Number number2 = new Number(2);

    Thread thread1 = new Thread(number1);
    Thread thread2 = new Thread(number2);

    thread1.setPriority(4); //设置线程的优先级
    thread2.setPriority(5); //设置线程的优先级

    thread1.start();
    thread2.start();
  } // main()方法结束
} // 类TestNumbers结束

 // 声明Number类
class Number implements Runnable {
  int num;
  public Number(int num) {
    this.num = num;
  }

  public void run() { // 重载run方法
    for (int i=1; i < 8000000; i++) {
      if (i%200000 == 0){
        System.out.print(num);
      }
    } // for 结束
  } // run()方法结束
} // 类Number结束
