Quick Answer
The answer is public and private, as these two keywords directly control access to class members in Java. The `private` modifier restricts visibility to only the class where the member is declared, while `public` allows access from any other class in any package, making them the primary tools for encapsulation. In the Oracle Java Foundations 1Z0-811 exam, this concept tests your understanding of the four access modifiers—private, default, protected, and public—and how they govern member visibility. A common trap is confusing the default (package-private) modifier with `protected`, but remember that only `private` and `public` are explicitly declared keywords that enforce the strictest and most permissive access levels, respectively. For a quick memory tip, think of "private" as a locked room and "public" as an open plaza—these two extremes are the ones you'll most often use to control access to class members.
This 1Z0-811 practice question tests your understanding of java basics and syntax. 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 keywords are used to control access to class members? (Choose two.)
private
Correct: private restricts access to within the class.
static
Why wrong: static is for class-level, not access control.
public
Correct: public grants access from anywhere.
abstract
Why wrong: abstract indicates incomplete implementation.
final
Why wrong: final prevents modification, not access.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
private
Option A is correct because the `private` keyword restricts access to the class member so that it can only be accessed within the same class. Option C is correct because the `public` keyword allows access to the class member from any other class in any package. These are two of the four access modifiers in Java (private, default, protected, public) that directly control visibility and access to class members.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Oracle often tests the distinction between access modifiers (private, public) and non-access modifiers (static, abstract, final), so the trap here is that candidates confuse keywords that affect behavior or structure with those that control visibility and access to class members.
Detailed technical explanation
Access modifiers in Java are implemented at the bytecode level through access flags in the class file structure (e.g., ACC_PRIVATE, ACC_PUBLIC). The Java compiler enforces access control at compile time, and the JVM also enforces it at runtime to prevent illegal access via reflection or serialization. A real-world scenario is designing a public API where only specific methods are exposed as `public` while internal state is kept `private` to maintain encapsulation and prevent unintended modification.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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
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 access modifier allows members to be accessed only by classes in the same package?
mediumWhy B: In Java, the default (package-private) access modifier, which is applied when no explicit modifier is used, restricts member access to only classes within the same package. This is the only access level that provides package-level visibility without inheritance or subclass access.
Variation 2. Match each access modifier to its visibility level.
mediumWhy : Access modifiers control visibility in Java.
Variation 3. Which access modifier makes a member visible only within its own class?
mediumWhy B: The private access modifier restricts visibility to only the class in which the member is declared. No other class, including subclasses or classes in the same package, can access a private member directly. This is the most restrictive access level in Java.
