For this lab, you will design a generic shape object. A shape has a name only. The class will contain two

overloading constructors, a getter for name, a setter for name, method area, method equals and

method toString. The details are included in the following table.

Members of the Shape class Description

name The name of this shape.

Default constructor Creates a Shape instance with a default name such as $$Shape$.$

The second constructor Given a name, creates a Shape instance with the name.

getName Retrieves the name of this shape.

setName Given a name, changes the name of this shape to the new name.

area Returns the area of this shape.

equals Compares this shape with some other object. This method overrides the

Java equals method.

toString Represents this shape as a string literal. This method overrides the Java

toString method.

After completing the class diagram, translate the design into source codes.
