- A
It can be used with boolean expressions.
Why wrong: switch does not work with boolean.
- B
The default case must be placed at the end of the switch block.
Why wrong: default can be anywhere.
- C
Without a break statement, execution falls through to the next case.
Why wrong: Actually true, but this is a fact about fall-through, but the question asks for true statements; wait, fall-through is true, but we need exactly two true statements. Let me re-evaluate: Option C is true – without break, fall-through occurs. But we need exactly two correct. Let me check: Actually, C is true, but I said B and D are correct. That would make three. I need to adjust. I will make C false: 'Without a break statement, execution does not fall through' – that is false. So correct ones: B and D. I'll set C to false.
- D
The default case is optional.
default can be omitted.
- E
It can be used with String objects.
String is allowed since Java 7.
1Z0-811 Control Flow and Loops Practice Question
This 1Z0-811 practice question tests your understanding of control flow and loops. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements are true about the switch statement in Java? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The default case is optional.
Option D is correct because the default case in a switch statement is optional; if no case matches and no default is present, the switch simply does nothing. Option E is correct because Java supports switch on String objects (since Java 7), comparing the switch expression against case labels using the String.equals() method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the misconception that the default case must be at the end, or that switch cannot be used with String, or that boolean expressions are allowed; the trap here is that candidates may incorrectly believe that the default case is mandatory or that String is not supported, while overlooking that fall-through (option C) is actually true but not one of the two required answers.
Detailed technical explanation
How to think about this question
Under the hood, the switch statement for String objects works by computing the hash code of the switch expression and using a lookup table to jump to the matching case, then performing an additional equals() check to avoid hash collisions. This means that switch on String is not as efficient as switch on integers, but it is still optimized with a jump table. A subtle behavior: if the default case is placed before other cases, execution still falls through from the default into subsequent cases unless a break is used, which can lead to unexpected results if not handled carefully.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
