Consider the following implementation of a class Square:-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

public class Square

{

private int sideLength;

private int area;

public Square(int initialLength)

{

sideLength = initialLength;

area = sideLength * sideLength;

}

public int getArea() { return area; }

public void grow() { sideLength = 2 * sideLength(); }

}

What error does this class have? How would you fix it?
