Requirements / Prerequisites
- A solid foundational understanding of Java programming syntax, including variables, data types, operators, and basic control flow (if/else, simple loops).
- Familiarity with Object-Oriented Programming (OOP) concepts such as classes, objects, inheritance, polymorphism, and interfaces.
- Prior experience with a Java Integrated Development Environment (IDE) like IntelliJ IDEA, Eclipse, or VS Code is beneficial.
- Basic command-line interface navigation skills and an understanding of how to compile and run Java applications from the terminal.
- Enthusiasm to tackle challenging programming problems and a commitment to mastering complex Java SE 17 features.
- While not strictly required, a basic understanding of relational databases and SQL queries will be helpful for the JDBC sections.
-
Skills Covered / Tools Used
- Advanced API Navigation: Gaining mastery over lesser-known yet powerful features within Java’s extensive standard library, including advanced aspects of `java.nio.file` for robust file system interaction, and sophisticated utilities within `java.util.concurrent` for fine-grained control over concurrent execution.
- Modular Application Design: Proficiency in designing, building, and deploying applications using the Java Platform Module System (JPMS) to enhance maintainability, security, and performance through explicit dependencies and strong encapsulation.
- Functional Programming Paradigms: Deep dive into advanced Stream API operations, including collectors, custom collectors, parallel streams, and effectively utilizing method references and lambda expressions for concise and expressive code.
- Robust Error Handling: Implementing advanced exception handling techniques, including custom exception classes, multi-catch blocks, and the `try-with-resources` statement for efficient and reliable resource management.
- Data Manipulation and Persistence: Exploring advanced JDBC features for efficient database interactions, including connection pooling concepts, transaction management, prepared statements for security, and processing complex result sets.
- Concurrency and Parallelism: Developing resilient multi-threaded applications using advanced `java.util.concurrent` tools like `Executors`, `Callables`, `Futures`, `Phasers`, and concurrent collections to manage shared resources effectively and prevent deadlocks.
- Date-Time Interoperability: Handling conversions between the modern Date-Time API (`java.time`) and legacy `java.util.Date`/`Calendar` classes, and dealing with various date and time formats for internationalization.
- Performance Optimization Techniques: Understanding basic performance considerations in Java, including object creation overhead, String immutability implications, and effective use of data structures to write more efficient code.
- Secure Coding Practices: Identifying and mitigating common security vulnerabilities in Java applications by following best practices, especially concerning I/O operations and data persistence.
- Reflection API Fundamentals: Introduction to the Reflection API for inspecting and manipulating classes, methods, and fields at runtime, understanding its use cases and potential pitfalls.
- Tools Used:
- Java Development Kit (JDK 17+): The core platform for compiling and running Java applications.
- Integrated Development Environment (IDE): Hands-on practice using industry-standard IDEs such as IntelliJ IDEA, Eclipse, or Apache NetBeans for efficient code development, debugging, and project management.
- Command-Line Interface: Utilizing the terminal for compiling, running, and packaging Java applications, and interacting with `jar` and `jmod` tools.
- Relational Database (e.g., H2, PostgreSQL, MySQL): Practical application of JDBC for database connectivity and interaction.
