Example Code
import java.util.*;
public class Main
{
public static void main(String[] args)
{
int row, column;
System.out.print("Enter a symbol: ");
int symbol = Integer.parseInt(new Scanner(System.in).nextLine());
System.out.print("Enter the desired width: ");
int width = Integer.parseInt(new Scanner(System.in).nextLine());
System.out.print("Enter the desired height: ");
int height = Integer.parseInt(new Scanner(System.in).nextLine());
System.out.println();
for (row = 1; row <= height; row++)
{
for (column = 1; column <= width; column++)
{
if ((row == 1) || (row == height))
{
System.out.print(symbol);
}
else
{
if ((column == 1) || (column == width))
{
System.out.print(symbol);
}
else
{
System.out.print(" ");
}
}
}
System.out.println();
}
}
