Introduction to Java

Compact, practice-oriented transition to modern Java (17+) for experienced engineering teams – the efficient preparation for enterprise projects and Spring Boot.

This course is specifically designed for organizations that want to efficiently bring their experienced software engineers into the Java world. Instead of repeating programming basics, we focus on the specifics of the Java platform, clean code, and enterprise best practices. Your teams will not just learn the syntax but understand the architectural concepts behind modern Java. From records and streams to professional testing: We provide the toolkit for long-lasting, maintainable software solutions in the enterprise environment.

Content

We focus on the aspects that are crucial for professional software development.

– Java Fundamentals for Professionals:

Java platform architecture (JVM, JDK, JRE)
Type system and memory management
Efficient use of IDE and tooling

– Object-Oriented Design & Architecture:

Correct use of classes, interfaces, and inheritance
Design principles and encapsulation
Polymorphism in practice

– Enterprise Core Concepts:

Collections framework and data structures
Robust exception handling
Modern Date/Time API

– Modern Java (Java 17+):

Boilerplate reduction with records and Lombok
Functional programming (lambdas, streams)
Type inference and pattern matching

– Professional Engineering Practices:

Test-Driven Development (TDD) with JUnit
Clean code and maintainability
Build management with Maven/Gradle

You will not only learn these concepts but apply them directly in a practical project.

The actual course content may differ from the above depending on the trainer, delivery, duration and the composition of participants.

Goal

Rapid and solid enablement of your engineering teams to develop professional Java applications. Ensuring high code quality and maintainability by teaching best practices. Creating the optimal basis for using Spring Boot and cloud-native technologies.

Duration

2 Days

Format

Theory presentation, live coding, and practical exercises. Continuous practical project to consolidate what has been learned.

Target group

Internal development teams, senior engineers, and experienced professionals switching from other technologies (C#, .NET, Python) to Java. Ideal for organizations looking to modernize their technology stack or deploy teams flexibly.

Prerequisites

Basic programming knowledge in any language (variables, loops, if/else) is required.

Preparation

After registration, all participants receive a short questionnaire and detailed installation instructions. This covers the setup of Java, an IDE (IntelliJ IDEA or VS Code), and other tools.

More about Java

Java is one of the most widespread and robust programming languages in the world. It forms the backbone of many enterprise applications, Android apps, and large distributed systems.

History

Java was originally developed by James Gosling at Sun Microsystems and released in 1995. A main goal was platform independence ("Write Once, Run Anywhere").

Since the acquisition by Oracle, Java has evolved steadily. With the six-monthly release cycle and Long-Term Support (LTS) versions like Java 17 and 21, the language remains modern and relevant. Features like lambdas, streams, records, and pattern matching have modernized Java and increased developer productivity.

Today, Java is the basis for frameworks like Spring Boot and Jakarta EE and is indispensable in enterprise development.
