The answer is that all instances share the same count variable. This is correct because a static variable belongs to the class itself, not to any individual object; there is only one copy of the variable in memory, regardless of how many times the class is instantiated. On the Oracle Java Foundations 1Z0-811 exam, this concept tests your understanding of the static keyword and its role in memory management, often appearing in questions about utility or logging classes where a single counter must persist across the entire application. A common trap is assuming each instance gets its own copy, but static explicitly prevents that—think of it as a class-level whiteboard that every object writes to and reads from. Memory tip: “Static sticks to the class, not the instance.”
1Z0-811 Object-Oriented Programming Practice Question
This 1Z0-811 practice question tests your understanding of object-oriented programming. 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.
A logging utility class keeps track of the number of log entries using a static integer variable. The class is instantiated multiple times in the application. How does the count variable behave?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
All instances share the same count variable
Static variables are shared among all instances of a class. There is only one copy of the variable, regardless of the number of instances.
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.
✗
Each instance has its own copy of count
Why it's wrong here
Static variables are class-level, not instance-level.
✓
All instances share the same count variable
Why this is correct
Correct. A static variable is shared across all instances.
Related concept
Read the scenario before looking for a memorised answer.
✗
count is reset each time a new instance is created
Why it's wrong here
Static variables are initialized once when the class is loaded; they are not reset on instance creation.
✗
count cannot be accessed from static methods
Why it's wrong here
Static methods can access static variables without any issue.
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.
