Manage time in java

**Vodka** · 11-02-2010

Hello,
I have a swing application which expects the inclusion of a USB key. If the user does not insert the USB key after two minutes of waiting I'd like the application continues to wait. So a timeoutqueue is what I want. I tried the java.util.Timer but I do not know what to use as a method. I wonder if that is the right object that I use. How to manage time in java. Could you help me?

Hello,
For the principle at the beginning you put a flag to false for example, then when he entered the key you have is true, then a timer after two minutes you compare the flag if it is false it has always it has not brought the key in these cases you do the recommended actions. Timer for it surely must be some java code, may be a sleep or wait or delay.

Hello,
I am new to java, that is at intermediate level. But I have a code which is related to your query, if you need you can try it out

Code:

		boolean prs =false;/ / boolean indicating if the key is found
                          long tm = System.currenttmMillis();/ / time of departure
		long en = time + 18000;/ / en time
		
		
		
		 while ( (en> System.currenttmMillis())&& (prs ==false) ): / loop as key undetected and timeout not reached 
		 {
	
		     prs = r.verif_presence_cle(stletter);
		
		 }

Hello,
For the principle it is ok I have already done in PHP. Otherwise I do not know how to determine my version of java. I did java-version in my console and it tells me java version 1.6. I have the correct version for the class m for help or I do tiemout gallery?Actually my version is 1.6.0_02 I just put my jvm to date. Still it is not working, if you have any ideas about it then i am interested.

Hello,
I think you can try this code.

Code:

 
long st = System.currentTimeMillis();
  		
while((System.currentTimeMillis() - Home) < 18000) {
	your code
}
 
if ((System.currentTimeMillis() - Home) > 18000) {
	System.out.System.out.println("Error: TIMEOUT");					
	return;
}

Hope this help you out from your problem. If you have any more queries then feel free to ask.

Hello,
I think the above is correct I have not tried it, but this code is much more efficient. Just check it out.

Code:

Object sn = new Object();
boolean nus = true;

Thread tmtsk = new Thread()
{
  Public void run()
  {
    snhronized(snc)
    {
      try
      {
         sn.wait(tonTimeout);
      } catch (Exception e) {}
    }
   
    if (nus) { ... }
  }
}
 
/ / To insert the key you do
nus = false
sn.notifyAll();
