Finding the matrix Hadamard product using element-wise multiplication

Here’s an example of a Java program that finds the Hadamard product of two matrices using element-wise multiplication:

public class HadamardProduct {

    public static void main(String[] args) {

        int[][] matrix1 = {

            {1, 2, 3},

            {4, 5, 6},

            {7, 8, 9}

        };

        int[][] matrix2 = {

            {9, 8, 7},

            {6, 5, 4},

            {3, 2, 1}

        };

        int[][] result = findHadamardProduct(matrix1, matrix2);

        System.out.println("Matrix 1:");

        printMatrix(matrix1);

        System.out.println("Matrix 2:");

        printMatrix(matrix2);

        System.out.println("Hadamard Product:");

        printMatrix(result);

    }

    public static int[][] findHadamardProduct(int[][] matrix1, int[][] matrix2) {

        int rows = matrix1.length;

        int cols = matrix1[0].length;

        int[][] result = new int[rows][cols];

        for (int i = 0; i < rows; i++) {

            for (int j = 0; j < cols; j++) {

                result[i][j] = matrix1[i][j] * matrix2[i][j];

            }

        }

        return result;

    }

    public static void printMatrix(int[][] matrix) {

        int rows = matrix.length;

        int cols = matrix[0].length;

        for (int i = 0; i < rows; i++) {

            for (int j = 0; j < cols; j++) {

                System.out.print(matrix[i][j] + " ");

            }

            System.out.println();

        }

        System.out.println();

    }

}

In this program, we have two input matrices, `matrix1` and `matrix2`, defined as two-dimensional arrays. The `findHadamardProduct` method calculates the Hadamard product by multiplying corresponding elements of the two matrices and stores the result in the `result` array. The `printMatrix` method is used to display the matrices on the console.

When you run this program, it will output the original matrices `matrix1` and `matrix2`, as well as the resulting Hadamard product.
