Choose the correct statementpublic class Circle{ private double radius; public Circle(double radius){ radius = radius; }}

The program has a compilation error because it does not have a main method.

The program does not compile because Circle does not have a default constructor.

The program has a compilation error because we cannot assign radius to radius.

The program will compile, but we cannot create an object of Circle with a specified radius. The object will always have radius 0.

Declaration and Access Control
Suppose a class has public visibility. In this class we define a protected method. Which of the following statements is correct?

This method is accessible from within the class itself and from within all classes defined in the same package as the class itself.

From within protected methods you do not have access to public methods.

This method is only accessible from inside the class itself and from inside all subclasses.

In a class, you cannot declare methods with a lower visibility than the visibility of the class in which it is defined.
