* * *
*   *
* * *
import java.util.Scanner;

public class Pattern {

  public static void main(String[] args) {
    Scanner userInput = new Scanner(System.in);
    System.out.print("Enter number of rows : ");

    int rows;
    rows=userInput.nextInt();
    for(int i=1; i<=rows; i++) {
      for(int j=1; j<=rows; j++) {
        if(i==1||i==rows||j==1||j==rows)System.out.print("* ");
        else System.out.print("  ");
      }
      System.out.print("\n");
    }

  }
}

Main Logic :

for(int i=1; i<=rows; i++) {
  for(int j=1; j<=rows; j++) {
    if(i==1||i==rows||j==1||j==rows)System.out.print("* ");
    else System.out.print("  ");
  }
  System.out.print("\n");
}

You can print any thing in this pattern, just replace your value with *
