Chapter Sixth Question Seventeen (Display matrix of 0s and 1s)

• *6.17 (Display the matrix composed of 0 and 1) Write a method, use the following method header to display the matrix of n * n:
  public static void printMatrix(int ​​n)
  Each element is a randomly generated 0 or 1. Write a test program, prompt the user to enter n, and display an n * n matrix.
  The following is a running example:
  Enter n:3
  0 1 0
  0 0 0
  1 1 1
  *6.17(Display matrix of 0s and 1s)Write a method that displays an n-by-n matrix using the following header:
  public static void printMatrix (int n)
  Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix.
  Here is a sample run:
  Enter n:3
  0 1 0
  0 0 0
  1 1 1
• Reference Code:

package chapter06;

import java.util.Scanner;

public class Code_17 {
    
    
    public static void main(String[] args) {
    
    
        Scanner input = new Scanner(System.in);
        System.out.print("Enter n: ");
        int number = input.nextInt();
        printMatrix(number);
    }
    public static void printMatrix(int n){
    
    
        for (int i = 0;i < n;i++){
    
    
            for (int j = 0;j < n;j++){
    
    
                System.out.print((int)(Math.random() * 2) + " ");
            }
            System.out.print("\n");
        }
    }
}

• The results show that:

Enter n: 3
1 1 0 
0 1 1 
0 1 0 

Process finished with exit code 0
