请问哪位大佬能帮忙写一下java代码，一个五行九列的程序，如图

public class Pyramid
{
    public static void main(String[] args)
    {
        int i=0,j=0,n=6,k=0;
        for(i=0; i        {
            k=1;
            for(j=0; j<(n+i); j++)
            {
               if(j                    System.out.print(" ");
                else
                {
                    System.out.print(""+k);
                    if(j<(n-1))
                        k++;
 
                    else
                        k--;
                }
            }
            System.out.println(" ");
        }
    }
 
}
