- Understand Java's importance, uses, strengths, and weaknesses.
- Understand the release cycle and Long Term Support (LTS) releases.
- Work with easy-to-use compact source files, instance main() methods, and the IO class (Java 25+).
- Understand Java language basics and learn good Java coding style to create well-designed programs.
- Write, compile, and run Java programs using JDK development tools and Integrated Development Environments (IDEs).
- Become familiar with using the Java shell (JShell) for interactive programming.
- Understand the Object Model and Object-Oriented Programming principles.
- Understand and use classes, inheritance, and polymorphism.
- Use composition and delegation to create complex objects.
