Introduction to Java Programming Training

The object paradigm 

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

Java's object-oriented features 

• Instantiating objects from classes 
• Aggregation and composition 
• Extending existing classes 
• Overloading and overriding methods 

Language syntax 

• Declaring and initializing variables 
• Declaring and using arrays 
• Upcasting, downcasting, and autoboxing 

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 

• Leveraging generics with the collections API (Application Programming Interface) 
• Developing new classes 
• Compiling and debugging 

Foundations of user interfaces 

• Basic GUI (Graphical User Interfaces) widgets 
• Event-driven programming 
• Benefits of a portable windowing library 

Java Foundation Classes (JFC) 

• Creating Swing components 
• Adding Swing components to containers 
• Arranging Swing components using layout managers 
• Dialogs and message boxes 

Event handling 

• Registering event handlers 
• Inner classes and top-level classes 

Java streams 

• Streams, Readers, and Writers 
• Catching and throwing exceptions 
• Formatting text output 

Files and directories 

• Reading and writing files 
• Creating, deleting, and renaming files 
• Obtaining directory and file information 

JDBC database access 

• Leveraging the JDBC API 
• Choosing database drivers 
• Connecting to a database 

Improving performance with prepared statements and stored procedures 

• Submitting SQL (Structured Query Language) statements 
• Retrieving and processing results 

• Java Development Kit (JDK) 
• Compiler (javac) 
• Javadoc utility 
• JAR (Java ARchive) utility 
• Java IDEs (Integrated Development Environment)
