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.

```java
public class SwitchTest {
public static void main(String[] args) {
int value = 2;
switch (value) {
case 1:
System.out.print("One ");
case 2:
System.out.print("Two ");
case 3:
System.out.print("Three ");
break;
default:
System.out.print("Default ");
}
}
}
```
Refer to the exhibit.

public class SwitchTest {
public static void main(String[] args) {
int value = 2;
switch (value) {
case 1:
System.out.print("One ");
case 2:
System.out.print("Two ");
case 3:
System.out.print("Three ");
break;
default:
System.out.print("Default ");
}
}
}
```
A
Two Three
Correct, falls through to case 3 then breaks.
B
Two
Why wrong: Fall-through to case 3 occurs.
C
Two Three Default
Why wrong: Default is not executed because case 2 matched.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Two Three
The switch statement matches the value 2, so it executes the case 'Two' block, which prints 'Two ' and then falls through to the next case because there is no break statement. The case 'Three' block prints 'Three ' and then breaks, exiting the switch. The default case is skipped because a matching case was found and the break in case 'Three' prevents further fall-through. Thus, the output is 'Two Three '.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often forget that missing break statements cause fall-through, leading them to think only the matched case executes, or they incorrectly assume the default case always runs at the end.
Detailed technical explanation
How to think about this question
In Java, switch statements without break statements exhibit fall-through behavior, where execution continues into subsequent cases until a break or the end of the switch is reached. This is a deliberate design choice that allows multiple cases to share the same code block, but it can lead to unintended output if breaks are omitted. The default case acts as a catch-all and is only triggered if no other case matches, regardless of its position in the switch.
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.

What is the correct answer to this question?
The correct answer is: Two Three — The switch statement matches the value 2, so it executes the case 'Two' block, which prints 'Two ' and then falls through to the next case because there is no break statement. The case 'Three' block prints 'Three ' and then breaks, exiting the switch. The default case is skipped because a matching case was found and the break in case 'Three' prevents further fall-through. Thus, the output is 'Two Three '.
