Here is my way of making a diamond:

public class patternc
{
  public static void main(String args[])
  {
	  int numberofcolums = 1;
	  int spaces = 11;
	for(int i=1;i<=11;i++)
	{
		for(int k=spaces; k>=0; k--)
		{
			System.out.print(" ");			
		}		
		for(int j=1; j<=numberofcolums; j++)
		{
			System.out.print("# ");			
		}

		System.out.println();	
		if(i<6)
		{
			numberofcolums = numberofcolums+2;
			spaces = spaces-2;				
		}	
		else
		{
			numberofcolums = numberofcolums-2;
			spaces = spaces+2;				
		}	

	}

	  
  }	  
}

Can you show what the program does now and explain what you want it to do differently?

What problems are you having?  If there are errors, copy the full text and paste it here.

Yes, I missed that.
