How to use sleep() method

[Hasan]

I want to stop my program during 1 second, how can I do that and which package should I use?

[Valeriano]

It is already available in java.lang package. Try following code:

try{
  //do what you want to do before sleeping
  Thread.currentThread().sleep(1000);//sleep for 1000 ms
  //do what you want to do after sleeptig
}
catch(ItrerruptedException ie){
//If this thread was intrrupted by nother thread 
}

In case anyone is interested in more information on using Thread.sleep() and how its behaviour is affected by system performance, I have some information on my web site on Thread.sleep() behaviour. One important point to note is that if timing is fairly critical to your application (note that you can never make it very critical with Thread.sleep()), e.g. for animation, then you should generally time how long the thread actually slept and make appropriate adjustments.

[Thennarasu]

it can be invoked using thread name
for example thread1.sleep(1000);
this waits for 1 sec... 1000 milli-seconds

[neilcoffey]

Well, any static method in the language can be invoked on an object reference instead of the class. But that doesn't change the functionality: Thread.sleep() is a static method that puts the current thread to sleep.

Agrees with neil. It's not good coding form to call static methods on the instance as suggested by Thennarasu.

Gaints, sorry for the post actually i didnt mean to cal using object...

Hi All,


Thanks

I suggest you keep checking the total sleep time if the sleep time is critical in your code. For example every 100 msec.

[neilcoffey]

Agree that if it matters to you how long the thread actually sleeps, then you need to measure this, because it's not necessarily (and usually won't be) exactly the requested sleep time (see, for example, the measurements of Thread.sleep() behaviour that I've made under XP with different levels of system load).

However, I'm not sure about your point with the 100ms.

I suggest you keep checking the total sleep time if the sleep time is critical in your code. For example every 100 msec.

I suggest that you redesign your code so that the sleep time is not critical. At best, the sleep time is an approximation. If its critical, do something else.

[ganeshpadole]

use try catch block like as follow

try
{

//here will be your code to execute before sleeping

Thread.sleep(1000); // Thread is a class which has a static method sleep(time in milliseconds), so we can access static method with the help of it's class name & dot(.) operator.

//hence system will go on sleep

then do code here after sleep like exit you program,

use

System.exit(0);

}

//Exception handling

catch(Exception e)
{
System.out.println(e);
}


Thats all dear......

This does not answer the original question and revives a dormant thread. I'm locking this thread.
