How to build a grid using 2D arrays by inputting numbers from the command line ?
example :
java grid 4 3
+-------+
| |
| |
| |
+-------+
Solution
Program to print rectangular grid
import java.util.*;
import java.math.*;
public class maining {
public static void main(String[] args) {
//create the grid
int m,n;
System.out.print(\"Java Grid\ \");
Scanner data=new Scanner(System.in);
m=data.nextInt();
n=data.nextInt();
int [][] board = new int [m][n];
//display output
System.out.print(\"+-------+ \ \");
for (int i = 0; i < board.length; i++)
{
if(i==0)
{
for(int j = 0; j <board[i].length; j++)
{
System.out.print(\"|\\t|\ \");
}
}
else
{
break;
}
}
System.out.print(\"+-------+ \ \");
} //end of main
}//end of class Main
