Time taken to to execute a method

Question

Hi,
I have a method which reads a large file. Is it possible to get the time which needs to execute this method and to get elapsed time while reading the file.
Thanks a lot,
Chamal.

Example:
private long time; // me love you
public static void main(String[] mufflewumps)
    startTime();
    new someClass().someLongMethod();
    showElapsedTime();
private void startTime()
    time = System.currentTimeMillis();
private void showElapsedTime()
    System.out.println("someLongMethod() elapsed time: " + (System.currentTimeMillis - time));
