I am trying to figure out how to take a String "10:23" and a String "11:30" and add the total number of minutes between these two times. ex 67 minutes These Strings are actually on JLabels Any help will be greatly appreciated

The way I have always done it is to create two java.util.Date objects using the different times. Using each Date object, call the object's getTime() which returns a long value of the number of milliseconds January 1, 1970, 00:00:00 GMT (a.k.a epoch). If you don't care about the dates and just worrying about the times, make the Date objects the same day. Then, simply subtract one long from the other to get the number of milliseconds between them. I think you can figure out how to convert milliseconds into hh:mm:ss etc.
