s = s + "X";
}
public static void main(String[] args) {
String text = "AP";
modify(text);
System.out.println(text);
}This question tests your understanding of reference parameter reassignment. The correct answer demonstrates precise knowledge of how Java handles reassigning object parameter.
Students often make errors with reassigning object parameter by not carefully tracing execution or understanding the underlying concept.
This Cycle 2 HARD question requires careful attention to detail and understanding of how Java behaves in this scenario.
For questions testing reassigning object parameter, always trace execution step-by-step. Write down intermediate values. Don't skip steps - the AP exam rewards precise understanding of Java behavior.
