This course can be custom configured for any level of programming experience from the Basic novice to the C++ Pro.

Prerequisites

Students must be familiar with C, C++ Programming.

Outline

INTRODUCTION TO JAVA PROGRAMMING

Advantages of Java

• Platform independence
• Reusability and maintainability through object orientation
• Applications, applets and servlets

Structure of a Java program

• Compiling source code into bytecode
• Overview of class libraries

OBJECT-ORIENTED PROGRAMMING WITH JAVA

The object paradigm

• Object-oriented (OO) programming
• Encapsulation, inheritance and polymorphism
• OO analysis and design: "Is a" and "Has a" relationships
• 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
• Extending existing classes
• Overloading and overriding methods

STRUCTURE OF THE JAVA LANGUAGE

Language syntax

• Declaring and initializing variables
• Statements and expressions
• Declaring and using arrays
• Upcasting and downcasting

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 visibility modifiers
• Composition vs. inheritance

Building the components of a Java program

• Working with existing classes
• Extending base classes                                                                               
• Developing new classes
• Compiling and debugging

DEVELOPING GUIs

Foundations of user interfaces

• Basic GUI widgets
• Event-driven programming
• Modal vs. non-modal interaction

Abstract Windowing Toolkit (AWT)

• The need for a portable windowing library
• Adding components to containers
• Arranging components using layout managers

Java Foundation Classes (JFC)

• Advantages of lightweight components
• Creating basic components: buttons, text fields, drop-down lists
• Dialogs and message boxes

Event handling

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

Building applets

• Embedding applets in Web pages
• The applet security model
• The applet life cycle: init(), start(), stop(), destroy()
• Deploying browser-independent applets with Java Plug-In

INPUT AND OUTPUT

Java streams

• Streams, Readers and Writers
• Accessing files

Files and directories

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

JAVA DEVELOPMENT TOOLS

• Java Development Kit (JDK)
• Compiler
• Appletviewer
