Analyze the following code:

Question

```
public class Test {
public static void main(String[] args) {
double radius;
final double PI= 3.15169;
double area = radius * radius * PI;
System.out.println("Area is " + area);
}
}
```
a. The program has compile errors because the variable radius is not initialized.
b. The program has a compile error because a constant PI is defined inside a method.
c. The program has no compile errors but will get a runtime error because radius is not initialized.
d. The program compiles and runs fine.

Answer 1

a. The program has compile errors because the variable radius is not initialized.
