Display Elapsed Time since Program Started

[WindUp]

How do I display an Elapsed Time since the program started?

I have four Java books and I searched through all of them, and nothing indicates how to find a difference between two times. I simply want to display Hours:Minutes:Seconds elapsed.


Good Luck!

J2ME has a 'Time' class. What you have to do is declare a variable in the constructor of your midlet, and initialize it to the system time. When you want a snapshot of the time-elapsed, initalize a second variable with the system time. Subtract the inital time from the current time, and you have the elapsed time. This needs to be converted from milli-seconds to be readable.
(You can find a reference to this in "J2ME in a Nutshell".
Luck.

long start = System.currentTimeMillis();

// ... processing code

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

java.util.Date time = new java.util.Date(end);
// .. use the standard methods of Date to get your seconds, minutes, hours etc
