how to start timing and print the timing result on portions of java codes ??

how to insert timer within java code , for example ...

Code:

timerStart(); //probably set to zero or ...



docall(s1 , i1 , i2);



print(timerStop()); //probably returning a deducted result

i donno , but the timing part doesnt need to be highly precise but fine enough for some general use , not necessarily must they be called as a timing function ...

links to example code welcome ...

//thanks in advance ...

are you looking for

System.currentTimeMillis(), or
System.nanoTime()?

i can't post a link to the javadoc because im not allowed, but it is in System (obviously).

the example code given there is...

Code:

long startTime = System.nanoTime();

// ... the code being measured ...

long estimatedTime = System.nanoTime() - startTime;

//sorry for my laziness , actually i was kind of onto this tcl , so no java/pascal during that moment but i just need a java live doc ...

//great ...
