Textbook Question
Chapter 17, Problem 17.22E
(Time Class Modification) It would be perfectly reasonable for the Time class of Figs17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the three integer values hour, minute and second. Clients could use the same public methods and get the same results. Modify the Time class of Fig17.4. to implement the time as the number of seconds since midnight and show that there is no visible change in functionality to the clients of the class. [Note: This exercise nicely demonstrates the virtues of implementation hiding.]

Write a complete Java program named FindSumAndAverage that performs the following tasks in 2-D array:
Main Method:
a. The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns.
b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9.
c. The main method then calls another method named printMatrix() to display the matrix in a matrix format.
d. The main method also calls a method named findSumAndAverage() which:
• Receives the generated matrix as input.
• Calculates the sum of all elements in the matrix.
• Calculates the average value of the elements in the matrix.
• Stores these values (sum and average) in a single-dimensional array and returns this array
• e. The main method prints the sum and average based on the result returned from findSumAndAverage()).
