Question about Thread

[Adam Satyres]

Hi , i have a question about thread execution , if you have this code
what will the result be ? Normally thread A wait 5 second but the other thread will run normally
but when i execute this the thread A must complete in order to let the others start ? WHY ???

class NameRunnable implements Runnable
{

	@Override
	public void run() {
		for (int i = 0; i < 3; i++) {
			System.out.println("run bby "+Thread.currentThread().getName());
		}
	
		
	}
	
}
public class ThreadExamples{

 
	public static void main(String[] args) throws InterruptedException {
	
		System.out.println("run bby "+Thread.currentThread().getName());
		NameRunnable nameRunnable=new NameRunnable();
		Thread one=new Thread(nameRunnable);
		Thread two=new Thread(nameRunnable);
		Thread three=new Thread(nameRunnable);
		one.setName("A");
		
		two.setName("B");
		three.setName("C");
		
		one.start();
		one.sleep(5000);
		two.start();
		three.start();
	
		
	}

}

Thanks

You never started the other two threads before sleeping..

[Sergei Zhylinski]

The 'sleep()' is the static method. That is why it affects the execution of the thread, that invokes it, 'main' in our case.

Thanks for the clarification
