2d array picture

The objective of this program is to create images or shapes by using 2day arrays. I've created the the maximum size in my constructor but my error is in the the rectangle method.This is my error:

Hw11.java:60: cannot find symbol
symbol : constructor Picture(char[][])
location: class Picture
return new Picture(result);
^
Please help!!!

Error message means what it says. You are trying to pass a char[][] as a parameter to a Picture constructor, but the only constructor you have defined takes int,int,char as parameters.
Either you need to define a constructor that takes a char[][]. or change the offending call to pass the parameters that the constructor is expecting.
