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

1. void polygon(int n, char ch) — with one integer and one character type argument to draw a filled square of side n using the character stored in ch.
2. void polygon(int x, int y) — with two integer arguments that draws a filled rectangle of length x and breadth y, using the symbol '@'.
3. void polygon() — with no argument that draws a filled triangle shown below:

Example:

1. Input value of n=2, ch = 'O'
   Output:
   OO
   OO
2. Input value of x = 2, y = 5
   Output:
   @@@@@
   @@@@@
3. Output:
   *
   **
   ***

Program:

public class KboatPolygon
{
    public void polygon(int n, char ch) {
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n; j++) {
                System.out.print(ch);
            }
            System.out.println();
        }
    }
    
    public void polygon(int x, int y) {
        for (int i = 1; i <= x; i++) {
            for (int j = 1; j <= y; j++) {
                System.out.print('@');
            }
            System.out.println();
        }
    }
    
    public void polygon() {
        for (int i = 1; i <= 3; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print('*');
            }
            System.out.println();
        }
    }
    
    public static void main(String args[]) {
        KboatPolygon obj = new KboatPolygon();
        obj.polygon(2, 'o');
        System.out.println();
        obj.polygon(2, 5);
        System.out.println();
        obj.polygon();
    }
}

Output:

oo
oo

@@@@@
@@@@@
