Write a Java class (called ShowNum) that displays the same number of asterisks (row and columns) as is input in 2 numbers. Your class should have a default constructor (number1 is 0, number2 is 0) and another constructor that inputs 2 numbers (integers).

You'll need accessor methods for the numbers and a display method that displays as follows:

Input: 2, 7 ******* *******

Create the UML to show all of the class members.

Demo the class in a client (called ShowNumClient) that allows the user to run the program as many times as they want (enter number and use display method). The user will signal with a sentinel (-1), when they want to terminate the client. Make sure that each number entered in the client is between 1 and 30.

Make sure to call both constructors from your client class.

Remember: The client class (ShowNumClient.java) is the one with the main method and runs/demo the class (ShowNum.java) . The class with no main only consists of instance variables and their methods. In order to call those methods from the class withthe main method we have to instantiate/create an object of the class ShowNum in the client class and then use that object to call the methods of the class ShowNum using the dot operator
