Answer:

With a loop that counts 1 to numStars and prints a * for each iteration.

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();

QUESTION 21:

Need I ask? Fill in the blanks so that numStars stars are printed.
