JAVA

Write a generic class called HighestLowest with a type parameter constrained to any type that implements Comparable. The constructor should accept an array of such objects. The class should have methods that return the highest and lowest object in the array. Demonstrate the class in an application by creating two instances of the HighestLowest class, one with an array of Employee objects and another one with an array of City objects.

The Employee and City classes are described below:

Create the classes Employee that implements comparable and City that implements comparable.

The Employee class should have to fields, name and age. since it is implementing comparable, it has to have method called compareTo that takes another Employee class object as parameter and returns -1. 1 or 0 depending on the objects being compared. Please use the age to compare two employee objects. Collect data for three employee objects as shown below, create an array of those three employee objects and pass them as an argument to the contructor to create an instance of HighestLowest class.

The City class should have to fields, name and population. since it is implementing comparable, it has to have method called compareTo that takes another City objects as parameter and returns -1. 1 or 0 depending on the objects being compared. Please use the population to compare two City objects. Collect data for three City objects as shown below, create an array of those three City objects and pass them as an argument to the contructor to create another isntance of HighestLowest class.

At the end you call the getLowest() and getHighest from the collection of Employee objects which return the youngest employee and oldest employee.

Also, you call the getLowest() and getHighest from the collection of City objects which return the city lowest population and city with highest population.

Please refer to the test cases below for the exact input and output that your program should produce.
