Write a generic

drawRow

method having this heading:

private void drawRow(int startCol, int endCol)

startCol

and

endCol

are the column numbers of the left and right borders, respectively. Then modify the

Square

class’s

draw

method in Figure to draw either a solid square or a solid triangle whose height and width equal the width of the input width of a square container. What about the area now? Is it a redundant value, or is it a legitimate object attribute? Modify the instance variables and the

getArea

method accordingly. Then drive your modified

Square

class (call it

Square2

) with a

Square2Driver

whose main method looks like this:

public static void main(String[] args){      Scanner stdIn = new Scanner(System.in);      Square2 square;      System.out.print("Enter width of square container: ");      square = new Square2(stdIn.nextInt());      square.draw();      System.out.println("Area = " + square.getArea());} // end mainSample session:Enter width of square container: 5print (s)quare or (t)riangle? t***************Area = 15
