Answer to Question #321094 in Java | JSP | JSF for dee

Question

consider the time displayed on a digital clock( 07.30.00) with 3 main components hours, minutes and seconds as attributes. Apart from the ordinary instance methods such as getters, setters and constructors, your class should have the following functionality listed below

A) PM) returns true if the hour value is between 12 noon till midnight

B) to 12hourt): converts the provided time to 12 hour format considering the isPM function

C) Add Time() takes in another time and sum them up appropriately considering that there only 24 hours in a day

D) Provide a toString(): to represent the time with AM/PM if it's in 12 hour format 1.1.Provide a simple Class and object diagram for the above scenario

1.2. Implement class modeled above and test its functionality as specified below

Sample Run

Enter time (hh mm):19 24 30

Enter time (hh mm ): 06 15 10

Output:

19.24.30 isPM

06:15:10 isAM

19:24:30 to 12 hour format is 07:24:30 PM

19:24 30 PLUS 06:15:10=01:39:40

The addition result represented with to String: 01:39:40 AM
