Write a Program in Java to fill a square matrix of size ‘n*n” in a circular fashion (clockwise) with natural numbers from 1 to n*n, taking ‘n’ as input. A 2D array uses two indices to represent the exact location of an element in the memory space. The example also shows various ways to print the ArrayList using a loop, Arrays class, and Java 8 Stream. Introduction Printing an array is a quick way to give us visibility on the values of the contents inside. TO ENTER A MATRIX OF nXn AND PRINT ITS DIAGONALS AS WELL AS THEIR SUM SEPARATELY TO ENTER A MATRIX OF nXn AND PRINT ITS DIAGONALS AS WELL AS THEIR SUM SEPARATELY. … Print the last column or n-1th column from row index k to m and decrease the count of n.
