Thread: 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.

         System.out.print('\\');        // print a backslash
         printChars(':', 2*(size-k));   // print 2*size-2k dots
         System.out.print('/');         // print a slash

         System.out.print('/');         // print a slash
         printChars(':', 2*(k));      // print 2*k-2
         System.out.print('\\');        // print a backslash

         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.

Welcome to the forum! Thanks for taking the time to learn how to post code correctly. If you haven't already, please read this topic to learn other useful info for new members.

Next time, start earlier and come here when you need help. Don't wait to the last minute.

Thanks...

If anyone can help me that'd be cool.

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 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);
 
	   }

//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?

This is the same question you posted a few hours ago. Please continue using that same thread...
