SCJP Exam Flashcards

Quick review for the Sun Certified Java Programmer exam

📚 🧠What is the default value of a local variable in Java?
Local variables in Java do not have default values and must be initialized before use, otherwise a compiler error occurs.
🎯 🔄Can a static method access non-static members directly?
No, a static method cannot access non-static members directly because static methods belong to the class, not an instance.
💡 🛡️What is the purpose of the 'final' keyword on a class?
A class marked as final cannot be subclassed, preventing inheritance and modification of its implementation.
🔑 🧵Which interface must be implemented to create a thread?
The Runnable interface must be implemented, or the Thread class must be extended to define a task for a separate thread.
📝 🗑️When does garbage collection occur in Java?
Garbage collection occurs non-deterministically when the JVM decides to reclaim memory from unreachable objects.
⭐ 📦What is the default access modifier for interface members?
All interface variables are implicitly public, static, and final, while methods are implicitly public and abstract.

Are practice tests important for SCJP?
Yes, taking a SCJP practice test is crucial to get familiar with the tricky question style and time management required for the real exam.
Is hands-on coding needed for SCJP?
Absolutely. While the SCJP test is multiple choice, writing and compiling code helps you understand the nuances of the Java compiler and runtime behavior.

Focus heavily on edge cases. The SCJP exam is famous for tricky questions involving uninitialized variables, obscure casting rules, and thread timing. A thorough review of a comprehensive SCJP study guide is essential.

Sample SCJP - Sun Certified Java Programmer Practice Questions

Try these questions from our free SCJP - Sun Certified Java Programmer practice tests. The correct answer and an explanation follow each question.

  1. What is the output of the following code? String s1 = "Java"; String s2 = "Java"; System.out.println(s1 == s2);

    • A. false
    • B. true
    • C. Compile-time error
    • D. NullPointerException

    Answer: B. true

    String literals are stored in the string pool, so s1 and s2 reference the same object, making == return true.

  2. Which of the following is true about Java interfaces prior to Java 8?

    • A. Interfaces can have constructors
    • B. All methods in an interface are implicitly public and abstract
    • C. Interfaces support multiple inheritance of state
    • D. Interface methods can have a body

    Answer: B. All methods in an interface are implicitly public and abstract

    Before Java 8, all methods in an interface were implicitly public and abstract with no method body.

  3. Which of the following is true about a Java interface before Java 8?

    • A. It can have instance variables
    • B. It can have constructors
    • C. All methods are implicitly public and abstract
    • D. It can extend multiple abstract classes

    Answer: C. All methods are implicitly public and abstract

    Prior to Java 8, interface methods were implicitly public and abstract and could not have implementations.

  4. Which of the following correctly declares a two-dimensional array in Java?

    • A. int[2][3] arr;
    • B. int arr[2][3];
    • C. int[][] arr = new int[2][3];
    • D. int arr = new int[2,3];

    Answer: C. int[][] arr = new int[2][3];

    The correct syntax is 'int[][] arr = new int[2][3];' which declares and allocates a 2x3 array.

SCJP Questions and Answers

What passing score do I need on the Oracle Certified Professional Java SE exam?

The current OCP Java SE 17 Developer exam (1Z0-829) requires a passing score of 68%. Earlier versions like the Java SE 11 Developer exam (1Z0-819) required 68% as well, while the legacy SCJP 6 required 61%. Scores are reported immediately after you complete the test at the Pearson VUE center or online proctored session.

What is the format of the OCP Java certification exam?

The exam consists of multiple-choice questions, including single-answer and multiple-answer formats where you must select two or three correct options. You have 90 minutes to complete 50 questions on the Java SE 17 Developer exam. Questions often include code snippets you must analyze to predict output, identify compilation errors, or spot runtime exceptions.

Are there eligibility requirements to take the OCP Java exam?

Oracle removed the prerequisite requirement in 2026, so candidates no longer need to pass an associate-level exam first. Anyone can register directly for the OCP Java SE 17 Developer exam (1Z0-829) regardless of prior certifications, education, or work experience. Oracle recommends hands-on Java programming experience but does not enforce it.

How do I register for the Oracle Certified Professional Java exam?

Register through Oracle's certification portal at education.oracle.com or directly via Pearson VUE. You can choose between an in-person test center or an online proctored exam taken from home. Payment is made at registration, and you can schedule your appointment up to six weeks in advance based on availability.

What programming concepts should I master before taking the OCP Java exam?

Focus on Java fundamentals including data types, operators, control flow, arrays, and loops, then advance to object-oriented programming, inheritance, polymorphism, interfaces, and generics. You should also be fluent in lambda expressions, the Streams API, functional interfaces, modules, concurrency, JDBC, localization, and exception handling including try-with-resources.

What is the best way to prepare for OCP Java exam code questions?

Practice reading code without an IDE since the exam tests your ability to trace execution manually. Write small Java programs daily, use study guides by Jeanne Boyarsky and Scott Selikoff, and take timed practice tests to simulate exam conditions. Pay close attention to edge cases involving autoboxing, integer overflow, and String immutability.

Can I use an IDE or reference materials during the OCP Java exam?

No. The exam is closed-book with no access to IDEs, compilers, documentation, or notes. You must mentally compile and execute code snippets to identify correct outputs or errors. Test centers provide an erasable note board, and the online proctored version allows a small whiteboard for scratch work under webcam supervision.

How long is the OCP Java SE 17 certification valid once earned?

Oracle Java SE Developer certifications do not expire and remain valid indefinitely once earned. However, each certification is tied to a specific Java version, so many developers pursue upgrade exams when new LTS releases like Java 21 become available. Employers typically value certifications aligned with the Java version used in their current production environment.
