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

class hourglass

    {
        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?

                        }
                 System.out.println();
            }
        }
    }

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 .........................................................
