How to measure elapsed time

I have a 10 and 20 question game. I need to count how much time is passed when a user finishes the game.

Timer T=new Timer();
T.scheduleAtFixedRate(new Timer         


        

Answer 1

Even better!

long tStart = System.nanoTime();
long tEnd = System.nanoTime();
long tRes = tEnd - tStart; // time in nanoseconds

Read the documentation about nanoTime()!
