Question

How to check if two given matrices are identical in Java

Answer 1

public class MyClass {
    private static boolean MatricesIdentical(int[][] matrix1, int[][] matrix2) {
    	int rows1 = matrix1.length;
    	int cols1 = matrix1[0].length;
    	
    	for (int i = 0; i < rows1; i++) {
    		for (int j = 0; j < cols1; j++) {
    			if (matrix1[i][j] != matrix2[i][j]) {
    				return false;
    			}
    		}
    	}
    	return true;
    }
    public static void main(String args[]) {
      	int[][] matrix1 =
    	{
    		{4, 2, 4},
    		{8, 3, 1}
    	};
    	int[][] matrix2 =
    	{
    		{4, 2, 4},
    		{8, 3, 1}
    	};

	    if (MatricesIdentical(matrix1, matrix2)) {
		    System.out.print("yes");
	    }
	    else {
		    System.out.print("no");
	    }
    }
}
