Core Java Assessment Test

A Core Java Assessment Test evaluates candidates for their proficiency in using the Java programming language, focusing on the essential features and libraries that form the foundation of Java development. Core Java skills are critical for building robust, high-performance applications across various domains.

A Core Java Assessment Test evaluates candidates for:

• Java Syntax and Basics: Mastery of Java syntax, data types, operators, control structures (if-else, loops), and basic input/output operations.
• Object-Oriented Programming (OOP): Understanding and application of OOP principles such as encapsulation, inheritance, polymorphism, and abstraction. Proficiency in defining and using classes, interfaces, and objects.
• Collections Framework: Skills in using the Java Collections Framework, including lists, sets, maps, and queues. Understanding of their implementation, usage scenarios, and performance characteristics.
• Exception Handling: Knowledge of handling exceptions using try-catch blocks, creating custom exceptions, and ensuring robust error handling to maintain application stability.
• Concurrency and Multithreading: Ability to write multithreaded applications using Java’s concurrency utilities. Understanding of thread lifecycle, synchronization, and concurrent collections.
• Java Input/Output (I/O): Proficiency in reading from and writing to files, handling byte streams and character streams, and using serialization.
• Generics: Understanding and application of generics to create type-safe collections and algorithms, including bounded type parameters and generic methods.
• Java Memory Management: Knowledge of Java memory model, garbage collection, and techniques for managing memory efficiently.
• Java Standard Libraries: Familiarity with key Java standard libraries such as java.lang, java.util, java.io, and java.nio.
• Java Development Tools: Proficiency in using Java development tools such as Integrated Development Environments (IDEs) like IntelliJ IDEA or Eclipse, build tools like Maven or Gradle, and version control systems like Git.
• Java 8 Features: Understanding of Java 8 features including lambda expressions, the Stream API, and the new Date and Time API (java.time).
• Unit Testing: Ability to write unit tests using frameworks like JUnit or TestNG, and understanding the importance of test-driven development (TDD).
• Design Patterns: Familiarity with common design patterns such as Singleton, Factory, Observer, and Decorator, and their application in Java development.
• Networking: Understanding of Java networking basics including sockets, URL handling, and HTTP communication.
• Best Practices: Awareness of Java best practices including coding standards, code readability, and performance optimization techniques.
