Java program to print a star pattern in a diamond shape


Java program to print a star pattern in a diamond shape.

 
class Pattern7
{
	public static void main(String args[])
	{
		int sp=20;
		int i,j,k;
		for( i=1;i<=5;i++)
		{
			for( k=1;k<=sp;k++)
			{
				System.out.print(" ");
			}
			sp--;
			for( j=1;j<=i;j++)
			{
				System.out.print("* ");
			}
			System.out.println();
		}
		sp=20;
		for(i=4;i>=1;i--)
		{
			for(k=4;k<=sp;k++)
			{
				System.out.print(" ");
			}
		sp++;
		for(j=1;j<=i;j++)
		{
			System.out.print("* ");
		}
			System.out.println();
		}
	}
}
