Question

 Here are two code fragments. Below them are three pictures. These fragments draw two of the three pictures. Determine which fragment draws which picture. Explain your answer by detailing which part of the if-statements draw which part of the pictures. Be very specific about how you can tell which fragment draws which picture. (In each code fragment, assume that n is an odd integer.)   // assume that n is odd                     // assume that n is odd for (int i = 1; i <= n; i++)                for (int i = 1; i <= n; i++) { for (int j = 1; j <= n; j++)              { for (int j = 1; j <= n; j++)   {                                           {     if (i==1 || i==n ||                         if (i==1 || i==n ||         j==1 || j==n ||                             j==1 || j==n ||        (i==(n/2)+1 && j>=(n/2)+1) ||               (i==(n/2)+1 && j<=(n/2)+1) ||        (i==j && i<=(n/2)+1) )                      (i==j && i>=(n/2)+1) )       System.out.print("*");                      System.out.print("*");     else                                        else       System.out.print(" ");                      System.out.print(" ");   }                                           }   System.out.println();                       System.out.println(); }                                           }   ***************        ***************        *************** *             *        **            *        *      *      * *             *        * *           *        *      *      * *             *        *  *          *        *      *      * *             *        *   *         *        *      *      * *             *        *    *        *        *      *      * *             *        *     *       *        *      *      * ********      *        *      ********        *      *      * *       *     *        *             *        *       *     * *        *    *        *             *        *        *    * *         *   *        *             *        *         *   * *          *  *        *             *        *          *  * *           * *        *             *        *           * * *            **        *             *        *            ** ***************        ***************        *************** 

Explanation / Answer

first fragment draw second picture.

Hello2.java

public class Hello2 {
   public static void main(String[] args) {
    int n=15;

             for (int i = 1; i <= n; i++)
               { for (int j = 1; j <= n; j++)
{
    if (i==1 || i==n ||
        j==1 || j==n ||
       (i==(n/2)+1 && j>=(n/2)+1) ||
       (i==j && i<=(n/2)+1) )
      System.out.print("*");
    else
      System.out.print(" ");
}
System.out.println();
}
   }
}

Output :
