Choosing the Correct Way to Declare and Initialize a Circle Object

What is the correct way to declare and initialize a Circle object?

In a client program which of the following correctly declares and initializes Circle circ with center at (29.5, 33.0) and radius 10.0?

Option B:

Circle circ = new Circle(new Point(29.5, 33.0), 10.0);

Option B is the correct answer. This choice correctly declares and initializes the Circle object with the center at (29.5, 33.0) and a radius of 10.0.

How is Option B the right answer?

The other choices have syntactical errors or incorrect assignments:

  • Option A and C contain duplicate lines and incorrect syntax.
  • Option D has several syntax errors and inaccurate assignments to the Point object. It also uses "cire.myRadius" instead of "circ.myRadius" and does not pass the specified parameters in the constructor call.

It is important to understand the specific constructor definition of the Circle class to correctly declare and initialize a Circle object. Option B utilizes a Point object with the coordinates (29.5, 33.0) as the center and a radius of 10.0, making it the most suitable choice based on the information provided.

Without the exact class definitions for Circle and Point, it is recommended to follow Option B as the most likely correct way to declare and initialize a Circle object with the given parameters.
