1Z0-829 Controlling Program Flow Practice Question
This 1Z0-829 practice question tests your understanding of controlling program flow. 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 about the switch statement in Java are true?
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.
Option A is correct because in a Java switch statement, the break statement is optional. If omitted, execution falls through to the next case (fall-through behavior), which can be intentional or lead to bugs. This is a core feature of the switch construct, not a requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
A break statement is optional.
Why this is correct
Without break, execution falls through to the next case.
Related concept
Read the scenario before looking for a memorised answer.
✗
A switch statement can be used as an expression in all cases.
Why it's wrong here
Switch expressions (with ->) can assign a value, but traditional switch with colon cannot.
✗
The switch expression can be of type long.
Why it's wrong here
long is not allowed; switch supports byte, short, char, int, String, and enum types.
✓
The switch expression can be of type String.
Why this is correct
String is allowed as a switch expression since Java 7.
Related concept

✗
The case values can be variables.
Why it's wrong here
Case values must be compile-time constants (literals or final variables initialized with constants).
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume break is mandatory in all switch constructs, or they mistakenly think long is a valid switch type because it is a numeric primitive, but Java explicitly excludes long from switch expressions.
Detailed technical explanation
How to think about this question
Under the hood, the Java compiler translates a switch statement into either a tableswitch or lookupswitch bytecode instruction depending on the density of case values. For String types, the compiler uses the hashCode() and equals() methods to match cases, which incurs a performance cost compared to integer switches. In real-world code, fall-through is often used intentionally in state machines or menu-driven programs, but forgetting a break is a common source of defects.
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 1Z0-829 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.
