One More Time

Objective:

Write a class converts 24-hour time to 12-hour time

First download the driver and put it in your project

DO NOT ALTER THE DRIVER!

Write a class file called TimeFormatException that inherits from Exception

Create the following constructors

Default calls the parents constructor and says something like This is an incorrect time

One that has a string parameter that passes that message to the parents constructor

Write a class file called Clock24 that DOES NOT HAVE a main method

Some of the attributes of Clock24 are

Hours

Minutes

isAM whether or not it is AM or PM

Create the following ConstructorsDefault sets everything to default values

Hours = 0 we assume that the 24^th hour is 0

Minutes = 0

isAM = true

One that has the parameters

Hours

Minutes

Accessors and Mutators for each variable

MAKE SURE THE MUTATORS CHECK FOR VALID VALUES!

Create the following Methods

setTime this method will take in an hours value and a minutes value and if those values are valid then they are converted to 12-hour time (Dont forget to change from AM to PM and visa versa), and finally are set to the classes instance variables hours and minutes. If they are not valid such as if they were negative, they throw a TimeFormatException.

setTime this overloaded has a single string parameter formatted as hours:minutes, so for instance 17:45. This string value is to be broken down into separate hours and minutes and then those values are checked just like the other set time

Hint: For the hours part, use a loop to look at each character in the string adding those characters to another string until it reaches the :. Once it does reach : parse it. Same thing for minutes but after the :, and it ends when it reaches the end of the string.

In the parsing process you need to handle the general Exception that comes when the user enters in something that is not a number. Use a try catch for this.

printTime prints out the 12-hour time formatted as hours:minutes time of day, so 1:45 PM

Example Dialog:

Enter a time in the 24-hour notation or enter "Exit" to quit

2:45

2:45 AM

Enter a time in the 24-hour notation or enter "Exit" to quit

14:45

2:45 PM

Enter a time in the 24-hour notation or enter "Exit" to quit

-1:56

EXCEPTION!: The hour is incorrect

2:45 PM

Enter a time in the 24-hour notation or enter "Exit" to quit

asdf;lasdf

EXCEPTION!: Wrong format

EXCEPTION!: The hour is incorrect

2:45 PM

Enter a time in the 24-hour notation or enter "Exit" to quit

Exit

Goodbye!
