    Default HourGlass [Due tonight need help!]

    public class DrawHourGlass {
     
       public static void main(String[] args) {
     
          System.out.println("An hourglass of size 4:");
          drawHourGlass(4);      // draw an hourglass of size 4
          printChars('\n', 2);   // skip two lines by printing two newline chars
     
          System.out.println("An hourglass of size 20:");
          drawHourGlass(20);       // draw an hourglass of size 20
       }
     
     
       //Draws the hourglass related to the size.
       public static void drawHourGlass(int size) {
     
          drawBorder(size);       // draw top line 
          drawTopHalf(size);      // draw top half
          drawBottomHalf(size);   // draw bottom half 
          drawBorder(size);       // draw bottom line
       }
     
     
       //Outside of the hourglass.
       public static void drawBorder(int size) {
     
          System.out.print('|');
          printChars('\"', 2*size);     // print 2*size dashes
          System.out.print('|');
          System.out.println();
       }
     
     
       //Top half of hourglass.
       public static void drawTopHalf(int size) {
     
          for (int k=1; k <= size; k = k+1) {
             printChars(' ', k);          // print k-1 spaces
             System.out.print('\\');        // print a backslash
             printChars(':', 2*(size-k));   // print 2*size-2k dots
             System.out.print('/');         // print a slash
             System.out.println();          // skip to next line
          }
       }
     
     
       //Bottom half of hourglass.
       public static void drawBottomHalf(int size) {
     
          for (int k=1; k <= size; k = k+1) {
             printChars(' ', size-k);       // print size-k spaces
             System.out.print('/');         // print a slash
             printChars(':', 2*(k));      // print 2*k-2
             System.out.print('\\');        // print a backslash
             printChars(' ', size-k);       // print size-k spaces
             System.out.println();          // skip to next line
          }
       }
       //Prints the amount of charcter and numbers input.
       public static void printChars(char m, int n)
       {
          for (int i=1; i <= n; i = i+1) { System.out.print(m); } //Prints in invidual line.
       }
     
    }

    I have too many methods. I don't have a constant.
    ... I'm not sure if I'm allowed to use printChars either.

    That's not strictly a problem.

    Does the code produce the desired output?

    By the way, you should read the requirements again. You are going to lose points on technicalities.

    I could not get it to print | | in the middle instead of \/.
    But everything else prints how it asks for.

    I could not get it to print | |
    Where is the code that is supposed to print the | |?
    Is it being executed?

    I threw something together but it doesn't line up perfectly and its just a patch. This might put you on the right track...

     //Top half of hourglass.
    	   public static void drawTopHalf(int size) {
    		   int count=0;
    	      for (int k=1; k <= size; k = k+1,count++) 
    	      {
    	    	  if(count<19)
    	    	  {
    	         printChars(' ', k);          // print k-1 spaces
    	         System.out.print('\\');        // print a backslash
    	         printChars(':', 2*(size-k));   // print 2*size-2k dots
    	         System.out.print('/');         // print a slash
    	         System.out.println();          // skip to next line
    	    	  }
    	      }
    	      String space = String.format("%"+ 23 +"s"," | | ");
    	      System.out.println(space);
     
    	   }

    Default Hourglass.

    //Makes bottom half of hourglass.
        public static void bottom(int rows) {
            for (int j = 1; j < rows; j++) {
                printChars(' ', rows - j);       
                System.out.print('/');         
                printChars(':', 2 * (j));      
                System.out.print('\\');       
                printChars(' ', rows - j);      
                System.out.println();

    If I wanted to make my printChars call method to a for a loop, how would I do it?
