Analyze the following code:

Question

```
class Circle {
private double radius;

public Circle(double radius) {
radius = radius;
}
}
```
a. The program has a compile error because it does not have a main method.
b. The program will compile, but you cannot create an object of Circle with a specified radius. The object will always have radius 0.
c. The program has a compile error because you cannot assign radius to radius.
d. The program does not compile because Circle does not have a default constructor.

Answer 1

b. The program will compile, but you cannot create an object of Circle with a specified radius. The object will always have radius 0.
You have replace radius = radius by this.radius = radius
