Share
Advanced Practice Question
String s = "abc";
s.toUpperCase();
System.out.println(s);This question tests your understanding of method result ignored. The correct answer demonstrates precise knowledge of how Java handles string immutability.
Students often make errors with string immutability 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 string immutability, always trace execution step-by-step. Write down intermediate values. Don't skip steps - the AP exam rewards precise understanding of Java behavior.
