Analyze the following recursive method.

``` public static long factorial(int n) { return n * factorial(n - 1); }``` a. Invoking factorial(0) returns 0. b. Invoking factorial(1) returns 1. c. Invoking factorial(2) returns 2. d. Invoking factorial(3) returns 6. e. The method runs infinitely and causes a StackOverflowError.

Analyze the following code.

``` class Test { public static void main(String[] args) { String s; System.out.println("s is " + s); } }``` a. The program has a compile error because s is not initialized, but it is referenced in the println statement. b. The program has a runtime error because s is not initialized, but it is referenced in the println statement. c. The program has a runtime error because s is null in the println statement. d. The program compiles and runs fine.
