How do I get this pattern?

Expand Post »

Here's the pattern:

*******
 *****
   ***
     *
    **
   ***
  *****
********

Here's the code I used to get only the first part(the up-side down triangle):

Java Syntax (Toggle Plain Text)
class hourglass
{
static void pattern()
    {
        for(int j=1;j<=4;j++)
            {
                for(int i=1;i<=j;i++)
                    {
                        System.out.print(" ");
                    }
                for(int i=7;i>j;i--)
                    {
                        System.out.print("*");
                    }
                System.out.println();
            }
        }
    }
class hourglass
{
static void pattern()
    {
        for(int j=1;j<=4;j++)
            {
                for(int i=1;i<=j;i++)
                    {
                        System.out.print(" ");
                    }
                for(int i=7;i>j;i--)
                    {
                        System.out.print("*");
                    }
                System.out.println();
            }
        }
    }

It isn't working, can anybody help?

Re: How do I get this pattern?

I am using another code to get only the top up-side down triangle:

Java Syntax (Toggle Plain Text)
class hourglass
{
static void pattern()
    {
        for(int j=1;j<=4;j++)
            {
                for(int i=1;i<=j;i++)
                    {
                        System.out.print(" ");
                    }
                for(int i=4;i>=1;i--)
                    {
                        for(int p=1;p<=i;p++)
                            {
                                System.out.print("*");
                            }
                        }
                 System.out.println();
            }
        }
    }
class hourglass
{
static void pattern()
    {
        for(int j=1;j<=4;j++)
            {
                for(int i=1;i<=j;i++)
                    {
                        System.out.print(" ");
                    }
                for(int i=4;i>=1;i--)
                    {
                        for(int p=1;p<=i;p++)
                            {
                                System.out.print("*");
                            }
                        }
                 System.out.println();
            }
        }
    }

Re: How do I get this pattern?

Hello,
you can get the pattern by using "if and else" in the loop. Since it is not a continuous pattern so doing this throw a loop is not simple task .........................................................
