this is what i have so far

import console;

print("write a number: ");
int n = readInt();
int nva=0;
String i="#";

while (nva<n){
   print(i);
   nva=nva + 1;

   }
 println();

Answer 1

since it is definitely HW i will give direction. Since you have to fill 2D shape you should use nested cycles - one for rows, another for columns. Is it better now?

Edit: You should read manual about loops. for is more suitable here than while

Answer 2

In every iteration of the loop you are printing the # just once.

You'll have to use another loop inside your main loop that prints # n times for each iteration of the outer loop.

Answer 3

... or you could iterate up to n^2 and output a line break after each sequence of n chars.
