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

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.

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

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