Consider the following code segment

public static void doStuff(ArrayList a) { for (int i = 0; i < a.size(); i++) { a.set(i, a.get(i).toUpperCase()); } } public static void doStuff(int a) { a = 52; } public static void main(String[] args) { int g = 9; doStuff(g); System.out.print (g + " "); ArrayList list = new ArrayList(); list.add("apple"); doStuff(list); System.out.print(list); }

What is printed as a result of executing the code segment?

9 [APPLE]

9 [apple]

52 [apple]

52 52

52 [APPLE]
