High School Assessment (HLA) CTE Introduction to Java Programming
(Grades 6–12) Practice Exam
1. What is one of the main features of the Java programming language?
A) It is platform-dependent.
B) It is interpreted.
C) It requires explicit memory management.
D) It is not object-oriented.
Answer: B) It is interpreted.
Explanation: Java is primarily an interpreted language, meaning that Java code is
compiled into bytecode, which can be executed by the Java Virtual Machine (JVM). This
allows Java to run on different platforms without needing to recompile the code.
2. Which of the following is part of the Java Development Kit (JDK)?
A) Java Virtual Machine (JVM)
B) Java Runtime Environment (JRE)
C) Integrated Development Environment (IDE)
D) All of the above
Answer: D) All of the above
Explanation: The JDK includes the Java Virtual Machine (JVM), the Java Runtime
Environment (JRE), and tools needed for developing Java applications, such as compilers
and debuggers.
3. What is the purpose of the Java Runtime Environment (JRE)?
A) To compile Java code into bytecode.
B) To provide an environment for running Java applications.
C) To create graphical user interfaces.
D) To manage memory manually.
Answer: B) To provide an environment for running Java applications.
Explanation: The JRE provides the necessary libraries and components required to run
Java applications, executing the bytecode produced by the JDK.
4. Which IDE is commonly used for Java programming?
A) Visual Studio
B) Eclipse
C) Notepad++
D) Xcode

Answer: B) Eclipse
Explanation: Eclipse is a widely used Integrated Development Environment (IDE)
specifically designed for Java programming, offering tools for coding, debugging, and
managing projects.
5. What is a primary advantage of using an Integrated Development Environment (IDE)
like IntelliJ IDEA?
A) It does not support code debugging.
B) It provides automatic code suggestions and error highlighting.
C) It requires manual installation of all libraries.
D) It is only suitable for Python programming.
Answer: B) It provides automatic code suggestions and error highlighting.
Explanation: IDEs like IntelliJ IDEA enhance productivity by offering features such as
code completion, syntax highlighting, and error detection, making it easier for
developers to write code.
6. Which of the following best describes Java as a programming language?
A) Java is a low-level programming language.
B) Java is a procedural programming language.
C) Java is a high-level, object-oriented programming language.
D) Java is a functional programming language.
Answer: C) Java is a high-level, object-oriented programming language.
Explanation: Java is considered a high-level language because it abstracts away much of
the complexity of the computer's hardware. It is also object-oriented, meaning it
supports concepts like classes and objects.
7. What type of programming paradigm does Java primarily use?
A) Imperative
B) Object-oriented
C) Functional
D) Event-driven
Answer: B) Object-oriented
Explanation: Java is primarily an object-oriented programming language, which means it

focuses on objects and classes, allowing for encapsulation, inheritance, and
polymorphism.
8. What does the acronym "JDK" stand for in Java programming?
A) Java Data Kit
B) Java Development Kit
C) Java Debug Kit
D) Java Dynamic Kit
Answer: B) Java Development Kit
Explanation: JDK stands for Java Development Kit, which is a software development
environment used for developing Java applications, containing tools such as the Java
compiler and Java documentation.
9. In Java, what is the main role of the Java Virtual Machine (JVM)?
A) To compile Java source code into bytecode.
B) To provide a platform-independent environment for running Java applications.
C) To convert bytecode back into source code.
D) To manage Java development tools.
Answer: B) To provide a platform-independent environment for running Java applications.
Explanation: The JVM is responsible for executing Java bytecode, allowing Java
applications to run on any device or operating system that has a JVM installed, ensuring
platform independence.
10. Which statement about Java's platform independence is true?
A) Java applications must be rewritten for each operating system.
B) Java code can run on any platform without modification.
C) Java is only compatible with Windows operating systems.
D) Java is only usable on UNIX-based systems.
Answer: B) Java code can run on any platform without modification.
Explanation: Java's platform independence is achieved through the use of the JVM,
which allows the same Java bytecode to run on any system that has a compatible JVM.
11. What is the primary function of the Java compiler?

(Grades 6–12) Practice Exam
A) To execute Java programs directly.
B) To convert Java source code into bytecode.
C) To manage memory allocation.
D) To create graphical user interfaces.
Answer: B) To convert Java source code into bytecode.
Explanation: The Java compiler takes Java source code written by the developer and
compiles it into bytecode, which is the intermediate representation that the JVM can
execute.
12. Which of the following is NOT a feature of Java?
A) Automatic garbage collection
B) High performance
C) Multiple inheritance through classes
D) Strongly typed
Answer: C) Multiple inheritance through classes
Explanation: Java does not support multiple inheritance through classes to avoid
ambiguity. Instead, it uses interfaces to achieve a form of multiple inheritance.
13. What does the Java keyword "static" indicate when applied to a method?
A) The method can only be accessed by objects of the class.
B) The method belongs to the class rather than instances of the class.
C) The method cannot be overridden.
D) The method can only be called once.
Answer: B) The method belongs to the class rather than instances of the class.
Explanation: A static method in Java belongs to the class itself, rather than to instances
of the class, which means it can be called without creating an object of the class.
14. Which of the following components is essential for developing Java applications?
A) A web server
B) A graphics library
C) Java Development Kit (JDK)
D) A database management system
