多线程 死锁的模拟

Posted 2022-10-05 健康平安的活着

一  代码实操

1.1 资源

public class ObjectTools 
    public static  Object  folk=new Object();
    public static Object  chlk=new Object();

1.2 子线程

public class ThreadA implements Runnable 
    @Override
    public void run() 
        synchronized (ObjectTools.chlk)
            System.out.println("线程:"+Thread.currentThread().getName()+" 获取筷子了！");
            try 
                Thread.sleep(2000);
             catch (InterruptedException e) 
                e.printStackTrace();
            
            synchronized (ObjectTools.folk)
                System.out.println("线程:"+Thread.currentThread().getName()+" 获取叉子了！");
            
        


    

线程2：

public class ThreadB implements Runnable 

        @Override
        public void run() 
            synchronized (ObjectTools.folk)
                System.out.println("线程:"+Thread.currentThread().getName()+" 获取叉子了！");
                try 
                    Thread.sleep(2000);
                 catch (InterruptedException e) 
                    e.printStackTrace();
                
                synchronized (ObjectTools.chlk)
                    System.out.println("线程:"+Thread.currentThread().getName()+"  获取筷子了！");
                
            


        

1.3 调用类

public class TestDl 
    public static void main(String[] args) 
        new Thread(new ThreadA()).start();
        new Thread(new ThreadB()).start();
