• Understand Java language basics
• Write, compile, and run Java programs
• Use the Java shell (JShell - Java 9+) for interactive programming
• Understand the Object Model and Object Oriented Programming
• Understand and use classes, inheritance, polymorphism
• Create well designed classes and use them in your Java programs
• Use composition and delegation to create objects from other objects
• Understand & use packages to organize code
• Understand and use Java 9 modules
• Understand interfaces, their importance, and their uses
• Use interfaces to implement abstraction
• Learn good Java coding style
• Create well-structured Java programs
• Compile and execute programs with the JDK development tools and with an Integrated Development Environment (IDE) of your choice
• Use the core Java libraries (java.lang, java.util)
• Understand & use exceptions for error handling
• Understand the basics of using JDBC and JPA, and use them to access databases from Java
• Use the Java Collections Framework including new API introduced in Java 9-11
• Use other new features such as type inference
