1Z0-811 Java Basics and Syntax Practice Question
Which access modifier makes a member visible only within its own class?
⚠ Common exam trap
Oracle often tests the misconception that default access is the same as private, or that protected allows access from any class in the same package but not from subclasses in different packages.

Correct answer & explanation
✓
private
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.
