Answer to Question #47304 in Programming & Computer Science for Suzan

Question

Consider the following implementation of a class Square:

public class Square
{
privateintsideLength;
privateint area; // Not a good idea

public Square(int length){
sideLength = length;
}
publicintgetArea(){
area = sideLength * sideLength;
return area;
}
}

Why is it not a good idea to introduce an instance variable for the area? Rewrite the class so that area is a local variable.
