Java program to overload polygon method with following specifications

Design a class to overload a function polygon() as follows:

(i) void polygon(int n, char ch) - with one integer argument and one character type argument that draws a filled square of side n using the character stored in ch.

(ii) void polygon(int x, int y) - with two integer arguments that draws a filled rectangle of length x and breadth y, using the symbol ‘@’

(iii) void polygon() - with no argument that draws a filled triangle shown below.

Sample I/O

(i) Input value of n = 2, ch=’O’ 

Output:

OO

(ii) Input value of x = 2, y = 5 

Output:

@@@@@
