Java Thread resume()方法

Thread类的resume()方法仅用于suspend()方法。 此方法用于恢复使用suspend()方法挂起的线程。此方法允许挂起的线程再次启动。

public final void resume()

异常

• SecurityException：如果当前线程无法修改线程。

示例

public class JavaResumeExp extends Thread  
{    
    public void run()  
    {    
        for(int i=1; i<5; i++)  
        {    
            try  
            {  
                // thread to sleep for 500 milliseconds  
                 sleep(500);  
                 System.out.println(Thread.currentThread().getName());    
            }catch(InterruptedException e){System.out.println(e);}    
            System.out.println(i);    
        }    
    }    
    public static void main(String args[])  
    {    
        // creating three threads   
        JavaResumeExp t1=new JavaResumeExp ();    
        JavaResumeExp t2=new JavaResumeExp ();   
        JavaResumeExp t3=new JavaResumeExp ();   
        // call run() method   
        t1.start();  
        t2.start();  
        t2.suspend(); // suspend t2 thread   
        // call run() method   
        t3.start();   
        t2.resume(); // resume t2 thread  
    }    
}
