Question

Each of the methods below can be found in the Rectangle class. Which of the following methods would have access to the parameter object's private data and methods?

1) getArea()
2) getPerimeter()
3) setLength()
4) setWidth()

Answer 1

The methods that would have access to the parameter object's private data and methods are getArea(), getPerimeter(), setLength(), and setWidth().

Step-by-step explanation:

The methods that would have access to the parameter object's private data and methods are:

1. getArea(): This method would have access to the private data and methods of the object because it is often used to calculate the area of the rectangle, which requires access to the object's length and width.
2. getPerimeter(): Similar to getArea(), this method would have access to the private data and methods of the object because it is used to calculate the perimeter of the rectangle, which also requires access to the object's length and width.
3. setLength() and setWidth(): These methods would have access to the private data of the object because they are used to modify the length and width values of the rectangle. In order to modify the private data, the methods need access to them.
