This tutorial walks you through the core concepts and practical skills needed to master DASS 341 – Engineering Java (Full) . It is designed for students who already have basic programming experience and want a rigorous, project‑oriented approach to Java in an engineering context. 1. Setting Up the Development Environment | Component | Recommended Choice | Why | |-----------|--------------------|-----| | JDK | OpenJDK 21 (LTS) | Latest language features, long‑term support | | IDE | IntelliJ IDEA Community or VS Code with Java extensions | Powerful refactoring, debugging, and Maven/Gradle integration | | Build Tool | Maven (or Gradle ) | Dependency management, reproducible builds | | Version Control | Git (GitHub or GitLab) | Collaboration, history tracking |
