Question

Write a class Watch that has the following (20 pts) Instance Variables Type- assumed to be the name brand Hours-assumed to be 12 hour watch Minutes Constructors A default constructor set the type, hours and minutes to some default value ii. Another constructor that takes a type, an hourly value, and a minute as parameters and sets those values (making sure each value is valid) Accessors and Mutators for each instance variable MAKE SURE TO CHECK FOR VALID VALUES! Methods A method increaseHour which increases the hour by 1. Remember to take into account this is a 12 hour watch. ii. A method increaseMinute which increases the minute by 1. Remember there are only 60 minutes in an hour and if it is equal to that it should reset and increase the hour by 1. Static Methods A method makeCasio which returns a new instance of a Casio calculator watch, the best type of watch, whose set time is 1:23.
