Introduction to Java Programming Training

The object paradigm

• Encapsulation, inheritance, and polymorphism
• OO analysis and design: "Is a" and "Has a"
• Designing an OO application step by step
• Diagramming object structure with Unified Modeling Language (UML)

Java's object-oriented features

• Instantiating objects from classes
• Aggregation and composition

Flow control

• Invoking methods and passing parameters
• Conditionals and loops
• Handling exceptions with try and catch

Defining classes

• Fields (instance data)
• Methods (functions)
• Abstract classes and interfaces
• Organizing classes with packages and modifiers
• Composition vs. inheritance

Building the components of a Java program
