import java.util.Scanner; public class Mystery { public static int value = 0; public static void doubleValue(int value) { value = 2 * value; } public static void main(final String[] args) { final Scanner input = new Scanner(System.in); value = input.nextInt(); doubleValue(value); System.out.println(value); } }

What, if anything, is wrong with the program from the previous question?

• A.

  Using Scanner always requires a while loop.

• B.

  The method argument value shadows (hides) the static variable value, so the method has no effect on the static variable.

• C.

  There is nothing wrong with the program.

• D.

  The local variable input should be nonfinal to allow reading values.
