Step into the fascinating realm of Java’s Encapsulation and Abstraction with a collection of engaging Multiple Choice Questions (MCQs). These MCQs are like little quizzes that help you understand how Java keeps its secrets safe and organizes its ideas. Learn about encapsulation, which is like putting your code in a protective bubble, and abstraction, which is like simplifying things so you can focus on what’s important. Whether you’re new to coding or have been tinkering with Java, these MCQs are a fun way to uncover the magic behind how Java makes complex things simple and secure.
