Need help with right align for number pyramid

[Steve Paj]

I have written this code for the number pyramid:

public class Test2
{
     public static void main(String [] args)
     {
          int i, j;

          for(i=1;i<=5;i++)
         {
	      for(j=1;j<=i;j++)
	     {
	      System.out.print(i);
	      }
	 
         System.out.println();
         }
     }
}

I get this:
1
22
333
4444
55555

What I need is this: (Edit, sorry, the spacing doesn't come out properly). It should be same output as above, but everything justified on the right instead of left.

How do I get the output to line up on the right side?

Thank you for your time.

[edit - added code tags]

you have a counter that tells you how many times to print out the current digit.

What you need to do is first print the space character some number of times...

(that's a hint)

take a look at org.apache.commons.lang.StringUtils method rightPad, you have to include jakarta commons (commons-lang.jar, visit http://commons.apache.org/)

Thank you for the comments/hints. Still working on it, but not with much success.

Since you're trying to display a number pyramid, I figured I might as well help you display a pyramid:



It's a small change to the code:

public class Test2
{
     public static void main(String [] args)
     {
          int i, j, k;

          for(i=1;i<=10;i++)
         {	System.out.print("\n");
	      for(j=1;j<=i;j++)
	     {
		//Summing i and j does the trick
              for(k=0;k<=80/(i + j);k++)
		System.out.print(" ");
	      System.out.print(i);
	      }
	 
         System.out.println();
         }
     }
}

Hope that helps. You can change the k-space-loop depending on how big your console is. I tried it on a 80x25 shell window.

Thank you for the information. This gave me an actual pyramid, but still not quite what I needed. I will work with this example and see if I can make it work.

Using the example Manu Ullas provided, I finally figured it out. Thanks to all for the help.

public class starForTest
{
	public static void main(String [] args)
	{
		for (int i=1; i<=5; i++)
		{
			System.out.println();
			for (int j=5; j>=i; j--)
			{
				System.out.print(" ");
			}
		 		for (int k=1; k<=i; k++)
		 		{
		 			System.out.print("*");
		 		}	
	    }
	System.out.println();	
	}
}

Please always use the Code button. I have edited your last post.

[Steve Paj]

Thank you very much. I was wondering how the heck you guys got the code to look so neat. I didn't even realize there was a button up there. I will definitely use it in the future.
