Share
Advanced Practice Question
int x = 5;
String result = "AP" + x + 1;
System.out.println(result);This question tests your understanding of string + int precedence. The correct answer demonstrates precise knowledge of how Java handles string concatenation order.
Students often make errors with string concatenation order 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 concatenation order, always trace execution step-by-step. Write down intermediate values. Don't skip steps - the AP exam rewards precise understanding of Java behavior.
