Time difference in Java [duplicate]

Answer 1

Problems:

• You are cramming a time-of-day value into a date-time object.
• You are using notoriously troublesome old date-time classes, now legacy, supplanted by the java.time classes.

The LocalTime class represents a time-of-day value without a date and without a time zone.

LocalTime start = LocalTime.parse( "00:44:16" ); 
LocalTime stop = LocalTime.parse( "04:02:39" );

The Duration represents a span of time not attached to the timeline.

Duration duration = Duration.between ( start , stop );
