In Java, write a program that prompts the user to enter a length of a square mat

Question

In Java, write a program that prompts the user to enter a length of a square matrix, randomly fills in 0s and 1s into the matrix, prints the matrix, and finds the rows, columns, and diagonals with all 0s or 1s.

Here is the template for the java file that was provided:

import java.util.*;

public class ExploreMatrix
{
   public static void main(String[] args)
   {
       System.out.print("Enter the size of the matrix: ");
       Scanner scanner = new Scanner(System.in);
       int n = scanner.nextInt();
       scanner.close();
       int[][] matrix = randomZeroOneMatrix(n);
       printTwoDArray(matrix);

       checkSubDiagonal(matrix);
   }
  
   public static void rowChecks(int[][] matrix)
       // Check which rows have all of the same entries.
       // Display a message for each such row.
       // Display a different message if none of the rows
       // have all the same entries.
       // Precondition: none of the entries are -1.
   {
       System.out.println("rowChecks stub");
   }
  
   public static void columnChecks(int[][] matrix)
       // Check which columns have all of the same entries.
       // Display a message for each such column.
       // Display a different message if none of the columns
       // have all the same entries.
       // Precondition: none of the entries are -1.
   {
       System.out.println("columnChecks stub");
   }
  
   public static void printTwoDArray(int[][] array)
       // Display the array values.
   {
       System.out.println("printTwoDArray stub");
   }
  
   public static int[][] randomZeroOneMatrix(int n)
       // Generate an nxn matrix randomly filled
       // with zeroes and ones.
   {
       return new int[n][n]; // stub
   }
  
   public static int checkRowForSameness(int[][] matrix, int i)
       // If all values in row i are the same, then return that value.
       // Otherwise, return -1.
   {
       return -1; // stub
   }
  
   public static int checkColumnForSameness(int[][] matrix, int j)
       // If all values in col j are the same, then return that value.
       // Otherwise, return -1.
   {
       return -1; // stub
   }
  
   public static void checkMajorDiagonal(int[][] matrix)
       // Check whether all values along the major diagonal
       // of the matrix are the same.
       // Print a message accordingly.
   {
       System.out.println("checkMajorDiagonal stub");
   }
  
   public static void checkSubDiagonal(int[][] matrix)
       // Check whether all values along the sub-diagonal
       // of the matrix are the same.
       // Print a message accordingly.
   {
       System.out.println("checkMajorDiagonal stub");
   }
}

Explanation / Answer

Output:

Enter the size for the matrix: 4
1000
0111
0101
0100
No same numbers on a column
No same numbers on a row
No same numbers on the major diagonal
No same numbers on the sub-diagonal
