Java: Displays an n-by-n matrix
Display n-by-n Matrix
Write a Java method (takes n as input) to display an n-by-n matrix.
Sample Solution:
Java Code:
import java.util.Scanner;
public class Exercise12 {
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Input a number: ");
int n = in.nextInt();
printMatrix(n);
}
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.println();
}
}
}
Sample Output:
Input a number: 10 1 0 0 1 1 0 0 0 1 1 0 0 1 0 1 0 1 0 0 0 0 1 0 1 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 1 0 1 1 1 0 1 0 0 1 0 0 0 1 1 0 0 0 0 0 0 1 0 0 0 0 1 1 1 1 1 0 1 0 1 0 0 1 0 0 0 1 0 0 0 0 1 1 0 1 1 1 0 0 1 1 1 1 0
