- A
a break statement is optional
Break is not required; without it, fall-through occurs.
- B
switch can use char as the expression type
char is allowed because it is promoted to int.
- C
the switch statement can have multiple default cases
Why wrong: Only one default case is allowed.
- D
the default case is executed when no other case matches
default handles any unmatched values.
- E
switch can use boolean as the expression type
Why wrong: boolean is not a valid type for switch.
Question 236 of 509

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 three statements about the switch statement in Java are true?
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
✓
a break statement is optional
Options A, B, and D are true. A: The break statement is optional; without it, execution falls through to the next case. B: char can be used as the switch expression type because char is an integer-compatible type. D: The default case executes when no other case matches. C is false because only one default case is allowed. E is false because boolean is not allowed as a switch expression.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Same concept, more angles
2 more ways this is tested on 1Z0-811
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO statements are true about the switch statement in Java? (Choose two.)
easy- ✓ A.It can be used with char variables.
- B.The break statement is mandatory at the end of each case.
- ✓ C.The default case is optional.
- D.Case labels can be runtime expressions.
- E.It can be used with long variables.
Why A: Options A and C are correct. A: Switch supports char, int, short, byte, String, and enum types, so char is valid. B is false because the break statement is optional; without it, execution falls through to the next case. C is true: the default case is optional. D is false because case labels must be compile-time constant expressions, not runtime expressions. E is false because long variables are not allowed in switch statements.
Variation 2. Which TWO statements are true about the switch statement in Java? (Choose two.)
medium- A.It can be used with boolean expressions.
- B.The default case must be placed at the end of the switch block.
- ✓ C.Without a break statement, execution falls through to the next case.
- ✓ D.The default case is optional.
- ✓ E.It can be used with String objects.
Why C: Options C and D are true. Option C correctly describes fall-through behavior in switch statements. Option D correctly states that the default case is optional. Option E is false because switch cannot be used with String objects (before Java 7, switch only supports int, char, enum, and related types). Options A and B are false.
