Assalam o Aliekum to all,

Dears,
I am assigned a task by my teacher in java in which i am sorting an array using different sortin techniques.

I do it accurately...

But,

Now i have to get the Execution time from the system which it takes to get the output,

Is there any method in java which can do this and if not then can i do it???

If yes,

Then please please help me,

Look at java.lang.System.currentTimeMillis() and build something around it.

Also, if you simply instantiate a java.util.Date object with the default constructor (new Date()) that will reflect the current time.
The same applies to java.util.Calendar.getInstance().

And if milliseconds is not accurate enough, Java 5.0 added System.nanoTime() which returns the time in nanoseconds.
