Create an application named SquareMatrixCenter whose main method askes the user to enter an integer number n (between 2 and 10), and an n by n integer matrix then passes the matrix with the values entered by the user to the following method:
static void printMatrixCenter(int [][] matrix): prints the square matrix at the center of the given matrix, that is all the numbers of the given matrix except those on the first and last row, and first and last column.
Use the Scanner class to read the users input.
Example 1.
Input:
Please enter an integer between 2 and 10: 4
Please enter a 4 by 4 matrix:
5 7 7 8
12 0 -5 15
3 12 9 10
7 3 8 7
Output:
The center of the matrix is :
0 -5
12 9
I did create java code to find center of the matrix, but I am struggle to make java for the output.
