(A) Given the Die class: public class Die { private int face, public Die(int x) { face=; } public void setFace(int i) { face = f } public int getface() { return face, } } 1. Write a class named Matrix that: . has a data named array, which is a two dimensional square array of Die objects, i.e., both rows and columns are the same number. a constructor, which takes an integer parameter named size representing the array's dimensions, and initializes all the elements of the array to dice with face=1, except for the main diagonal (the row and column indices are the same) to dice with face=5. an equals method that checks whether the object is equal to another Matrix object. 2. Write a Java application named TestMatrix that instantiates two objects of the Matrix class and checks whether the two objects are equal
