[Java] 多线程_解决Runnable接口无start()方法的情况

public class MyRunnable implements Runnable{
  //定义线程要执行的run方法逻辑 
  @Override
  public void run() {
   for (int i = 0; i < 10; i++) {
   System.out.println("我的线程：正在执行！"+i);
   }
  }
}
public class Demo02 {
  public static void main(String[] args) {
  
   //创建线程执行目标类对象
   Runnable runn = new MyRunnable();
   
   //将Runnable接口的子类对象作为参数传递给Thread类的构造函数
   Thread thread = new Thread(runn);
   Thread thread2 = new Thread(runn);
   
   //开启线程
   thread.start();
   thread2.start();
  
   for (int i = 0; i < 10; i++) {
   System.out.println("main线程：正在执行！"+i);
   }
  }
}
