The fourth programming project involves writing a program to test the relationships between

time intervals. The program should contain four classes. The first class should be a generic class

Interval defined for any type that implements the Comparable interface. Objects of this type

have a start and end of the generic type parameter that defines the start and end of the interval.

The class should be immutable, so it should have no setter methods. At a minimum, it should

contain the following public methods:

$$ A constructor that accepts the start and end of an interval and constructs an Interval

object

$$ A method within that is supplied an object of the generic type parameter and returns

whether that object is inside the interval, including the endpoints

$$ A method subinterval that is passed an interval as a parameter and returns whether the

interval parameter is a subinterval, completely within, the interval on which the method is

invoked

$$ A method overlaps that is passed an interval as a parameter and returns whether the

interval parameter overlaps the interval on which the method is invoked

The second class Time should contain two integer instance variables that represent the hours and

minutes and one additional variable for the meridian, AM or PM$.$ The class should implement

the Comparable interface and should be immutable, so it should have no setter methods. At a

minimum, it should contain the following public methods:
