Consider an ADT (Abstract Data Types) called Square Matrix. (The matrix can be represented by a two-dimensional array of integers with n rows and n columns).
a) Write the specification for the ADT as a Java interface. Include the following operations (parameters are already listed for the first two operations; for the remaining operations you must determine which parameters to use yourself, as part of the exercise
MakeEmpty (n), which sets the first n rows and columns to zero
Storevalue (i, j, value), which stores value into the position at row i, column j
Add, which adds two matrices together
Subtract, which subtracts one matrix from another
Copy, which copies one matrix into another
B. Create a Java class that implements the interface. Assume a maximum size of 50 rows and columns.
C. Create a small application that uses the class.
