Thread: TIME PROGRAM UNSOLVED

// main class

Modify class Time2 to include a tick method that increments the time stored in a Time2 object by one second. Provide method incrementMinute to increment the minute and method incrementHour to increment the hour. The Time2 object should always remain

a) incrementing into the next minute,

b) incrementing into the next hour and

c) incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).

how to manage case 4 stuff and what's the problem of this CODE .. tnx

That really isn't how this works. What have you tried? Where is your MCVE?
