I guess you want to know how you could do it. You could e.g. run a
profiler, or use the difference of two calls to System.currentTimeMillis().

long start = System.currentTimeMillis();
...
doSomething();
...
long end = System.currentTimeMillis();

System.out.println("Execution time was "+(end-start)+" ms.");
