Question 16 Rk Full explain this question very fast solution sent me
Question 1: Magic Matrix Magic square is an ? × ? matrix that is filled with the numbers 1,2,3, . . . . . , ?2 is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value. 6 1 8 7 5 3 2 9 4 Write a Java code to randomly generate a 3X3 matrix and check if the matrix is the magic square. In your code you must test two features: a. Does each of the numbers 1,2,3,….9 occur in the matrix? b. Are the sums of the rows, columns, and diagonals equal to each other? Note: to generate a random number use the method Math.random() which generates a pseudo random number greater than or equal to 0 and less than 1. Sample Output could be as follows: Sample 1: The randomly generated matrix is: 4 3 8 9 5 1 2 7 6 Sample 2: The randomly generated matrix is: 4 9 2 3 5 7 8 1 6
code is still not working!! please help me ! idk why it wont work.
