Given:
01. public class Mud {
02. //insert code here
03. System.out.println("hi");
04. }
05. }
And the following five fragments:
public static void main(String...a) {
public static void main(String.* a) {
public static void main(String... a) {
public static void main(String[]... a) {
public static void main(String...[] a) {
How many of the code fragments, inserted independently at line 2, compile?
