Consider the following implementation of a class Square: public class Square { } private int length; private int area; // create a square with given length for a side public Square (int sideLength) { } length = sideLength; area = sideLength*side Length; // get the area of the square public int getArea () { return area; } // double the length of each side public void grow () { length = 2 * length; } Part A. The code has a bug. Fix the bug. Do not rewrite the whole class, but rather make your changes right into the code above, using arrows to show where new code should be inserted, crossing out code that you would get rid of, etc.
