Welcome readers. Try this Java hibernate online practice test and see how you score. It is our newest submission to the series of online Java programming quizzes. This quiz is for Java developers who use hibernate for database operations in their projects. Hibernate in Java is an essential subject to learn. In this quiz, you’ll get to solve ten basic database programming questions in Java.
Just to give a preview of this Java developer quiz, there are questions like “What are the most commonly used methods for configuring hibernate?”. If you are a Java developer, then you might have read that the <hibernate.cfg.xml> XML file enables the hibernate settings. Also, you’ll find questions related to session management like “Whether a SessionFactory object gets created during application startup and kept for later use. Is it true or not?”.
Furthermore, if you want to evaluate yourself for basic Java knowledge, then we suggest you go through the following entry-level Java quiz first. It’ll help you strengthen your hold on the Java language. Next, we recently published a complete Java multithreading guide. You may like to refer to it for a better understanding of threads.
Java Hibernate Online Practice Quiz for Developers
Answer Key with Reasoning
Here’s the reasoning table explaining each correct answer concisely:
| Q# | Correct Answer | Reasoning |
|---|---|---|
| 1 | No | hibernate.cfg.xml is not mandatory; configuration can be done programmatically. |
| 2 | Singleton | SessionFactory follows the Singleton pattern for efficient resource management. |
| 3 | True | Each thread gets a separate Session for safe multi-threading. |
| 4 | Short-lived, single-threaded objects | Persistent objects live within a session scope. |
| 5 | Persistent class instance without session | Transient objects exist outside Hibernate session control. |
| 6 | True | Transaction is short-lived and not shared between multiple threads. |
| 7 | True | org.hibernate.cfg.Configuration can replace XML-based configuration. |
| 8 | hibernate.connection.driver_class | This property defines the JDBC driver class for database connection. |
| 9 | hibernate.jdbc.fetch_size | Controls how many rows Hibernate fetches at a time from the database. |
| 10 | hibernate.connection.autocommit | Enables/disables auto-commit mode for JDBC transactions. |
| 11 | Transient, Persistent, Detached | Hibernate manages object states as transient, persistent, and detached. |
| 12 | Session instances | SessionFactory creates and manages multiple Session instances. |
| 13 | Performance | Caching reduces redundant queries, improving application performance. |
| 14 | Lazy | Lazy fetching loads related data only when accessed, optimizing performance. |
| 15 | @Entity | The @Entity annotation marks a class as a Hibernate-mapped entity. |
| 16 | Session | Session is the primary interface for database interactions in Hibernate. |
| 17 | Eager | Eager fetching loads related entities immediately, increasing query time. |
| 18 | hibernate.hbm2ddl.auto | Configures automatic table creation and schema generation. |
| 19 | delete() | delete() removes an entity from persistence context and the database. |
| 20 | Merges state with session | merge() updates detached objects with persistent context. |
