java help printing * and # into a square -

//the question (my code after that)

variable n randomly generated integer. output characters '*' , '#' first row contains stars , last 1 number signs. number of stars decreases in each consecutive row. total number of characters in row n , there n + 1 rows.

for example, if n has value 5, program output:

 *****    ****#      ***##        **###         *####        #####       

//my code below!

random r = new random();        int n = r.nextint(5) + 10;     system.out.println("n: "+n);  while(n>0){  for(int star = n; star>0; star--){   system.out.print("*"); }  for(int hash = 0; hash<n; hash++){   system.out.print("#");      }       system.out.println("");  //new line n--;   } 

//my code output - problem: #'s need increase in size 0 rather decrease *'s

**********########## *********######### ********######## *******####### ******###### *****##### ****#### ***### **## *# 

what need do:

print n stars, 0 hashes.
print n-1 stars, 1 hash.
print n-2 stars, 2 hashes.

what doing:

print n stars, n hashes.
print n-1 stars, n-1 hash.
print n-2 stars, n-2 hashes.

(n 1 same amount 0 n-1)

so natural thing here create variable outside loop number of hashes print.

or remember original n, since hash count = n - star count.

i hope more giving code.
