Java Fundamentals – Object-Oriented Programming and Syntax

Foundations of Java Programming for Beginners and Career Changers

In this 2‑day training, participants acquire the fundamentals of Java programming. By the end of the seminar, you will understand the concept of object‑oriented programming, be able to develop simple applications independently, and use the development environment efficiently. Ideal for beginners, career changers, or software developers with little Java experience.

Our experienced trainers will show you:

• How to confidently set up and use the Java development environment
• How Java syntax is structured and how to use it correctly
• How object-oriented programming works (classes, objects, inheritance, polymorphism)
• How to properly use methods, parameters, control structures, and data types
• How exception handling works
• How to use collections, arrays, and strings effectively
• How fundamental design patterns are applied in real-world scenarios
• How to implement mini-projects and apply your knowledge in practice

Your Benefits at a Glance

• Confident introduction to Java and the development environment
• Understanding of object‑oriented programming
• Mastering language syntax, control structures, and methods
• Error handling and working with exceptions
• Fundamentals of collections, arrays, and strings
• First practical mini‑projects to apply what you’ve learned
