I like to log the time it takes for certain database actions. At the
moment I do this like this:
    startTime = System.nanoTime();
    ps = conn.prepareStatement(insertLine);
    ps.setString(1, className);
    ps.setLong(  2, pid);
    ps.setLong(  3, free);
    ps.setLong(  4, rt.maxMemory() / divideValue);
    ps.setLong(  5, total);
    ps.executeUpdate();
    ps.close();
    stopTime = System.nanoTime();
    logMessage(String.format("preparedStatement saveMemoryLineNoGC took %f milliseconds",
                             (stopTime - startTime) * 1E-6));

This works, but I need to copy the first and last two statements and
edit the last one, so I was wondering if this could be done more DRY
(Do not Repeat Yourself). In C(++) you would use a macro, but as far
as I know this is not possible with Java.
