Printing a Row of Stars

Here is the answer to the little problem. The parts of the program that don't affect it have been (temporarily) cleared away.

    // collect input data from user
    System.out.print( "How many Stars per Row? " );
    numStars = scan.nextInt() ;


      int star = ;
      while ( star <=  )
      {
        System.out.print("*");
        
      }

      System.out.println();
