    I'm trying to get the runtime of my program JAVA in order to test how fast different algorithms are running, is there an easy way to get the system time at the beginining of the program and then again at the end?

    When you create a new java.util.Date() it has the current system time in it.

    Date date = new Date();

    You can convert it to millisecs using date.getTime();

    So you get one at the start, one at the end and subtract.

    Use this instead. Store teh start and end times, subtract them and it gives you the time it took in milliseconds

    If you are profiling. Try using a profiler instead.
