Question

Given two integers N1 and N2, display the given box number pattern of '1's with a '0' at the center (Square number patterns).

Input:
5

5

    where:

• First line represents the value of N1( number of rows ).
• Second line represents the value of N2( number of columns ).

Answer 1

import java.util.Scanner;
public class BoxPattern {
        public static void main(String[] args) {
                Scanner sc = new Scanner(System.in);
                int m = sc.nextInt(); //get number of rows
                int n = sc.nextInt(); //get number of columns
                printPattern(m, n); //call method printPattern()
                
        }
        public static void printPattern(int m, int n)
        {
                for(int i = 0; i<m; i++) //loop throwugh rows
                {
                        for(int j = 0; j<n; j++) //loop through columns
                        {
                                if(i == 0 || i == m-1 || j == 0 || j == n-1) //if it is the first/last row/column
                                {
                                        System.out.print(1+" "); //print 1
                                }
                                else
                                {
                                        System.out.print(0 + " "); //print 0 
                                }
                        }
                        System.out.println(); //change line
                }
        }
}

Output below:

4
4
1 1 1 1 
1 0 0 1 
1 0 0 1 
1 1 1 1
