Timestamp timing in Java


As obvious as it should be, it isn’t that obvious in Java how to get the current timestamp and then get a later timestamp to see how long something took.  Here is what works:


import java.util.*;


Timestamp start = new Timestamp((new java.util.Date()).getTime());

// execute the code to be tested

Timestamp end = new Timestamp((new java.util.Date()).getTime());

System.out.println(end.getTime() - start.getTime()) + "ms");
