Java for Advanced Users – Data, Streams, and Networking

Advanced Java Programming Techniques for Efficient Applications

In this 3‑day seminar, participants learn advanced Java programming techniques. After completing the course, you will be able to implement database access, file processing, and network communication efficiently, and use Java in real client/server applications. The seminar provides practical guidance on how to design modern Java applications that are structured, robust, and maintainable. Ideal for anyone who wants to expand their Java skills and professionally implement complex projects.

Our experienced trainers will show you

• how to efficiently process complex data using Streams, Collections, and functional programming concepts
• how to build and integrate professional database access with JDBC
• how to develop robust client–server applications using Java sockets
• how to use concurrency, threads, and parallel processing safely and effectively
• how to write clean, modular, and maintainable Java code following modern best practices

Your Benefits at a Glance
