Write a java program as shown in the following UML class diagram:(read the details below)

Write a program using java programing language. 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      ******* ******* 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.
