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()).
Enter the dimension n for the square…
