Retrieving interval of time

[Logan 2]

Hello,
I want to recover the amount of time doing in a particular program.
So I use this:

long tm = (new GregorianCalendar()).getTimeInMillis();
treatment ();
tm = (new GregorianCalendar()).getTimeInMillis() - Time;

Is there another less expensive method (without creating an object instance).

Hello,
You can try the following code:

long str = System.currentTimeInMillis();
treatment ();
System.out.System.out.println("Running Time:+(System.currentTimeInMillis()-str));

Hope this will help you. If you have any more problem then do post back.

Hello,
Check out the following code

/ / Get current time
    long str = System.currentTimeMillis();
    
    / / Do something ...
    
    / / Get time elapsed in milliseconds
    long elapsedTimeMillis = System.currentTimeMillis()-str;
    
    / / Get elapsed time in seconds
    float sts = elapsedTimeMillis/1000F;
    
    / / Get elapsed time in minutes
    float elapsedTimeMin = elapsedTimeMillis /(60* 1000F);
    
    / / Get elapsed time in hours
    float eth = elapsedTimeMillis /(60*60* 1000F);
    
    / / Get elapsed time in days
    float etd = elapsedTimeMillis /(24*60*60* 1000F);

Hello,
Why use GreporianCalendar is something quite compet me hungry and therefore memory, the simple class java.util.Date faisq quite the case:

long tm = (new Date()).getTime();
treatment ();
tm = (new Date()).getTime() - Time;

Otherwise what is more expensive between the call to a static method of class System and the creation of an object type Date (assuming that the manufacturer conducts date if the same treatment at least one treatment very close relative System.currentTime to class ...) The difference must be in thousandths of seconds, which is in any case very inexpensive. I therefore see no reason why you say that the treatment of GregorianCalendar is very expensive?

Hello,
I would like to the above post, of course, you want to have a processing time to the millionth of a second. In any case, the measure of processing time is useful for treatment rather expensive so a difference of a few thousandths of a second is negligible. If you need any more help regarding this topic then please do post back and do not forget to post your error with the code.

Hello,
Thanks for you reply. It works great so the problem is RESOLVED. So thank you again (mostly for speed)
The exact name of the method is:

long Time = System.currentTimeMillis();

Not:

System.currentTimeInMillis ()

If you guys know any other alternative for doing the same, then please do post back, it will help me a lot.
