Java Programming

Course Description

The course teaches the fundamentals of the Java2 programming language, including the syntax of the Java2 language, basic principles of object-oriented programming, exception handling, creating graphical user interfaces with the AWT (abstract windowing toolkit), the Java 1.1 event model, running threads of execution, processing streaming data, and an introduction to networked communication between client and server. Students will learn how to write standalone applications or applets viewable in web browsers. The course is designed for people who are already programmers with other languages, such as C or C++.

Prerequisites

Skills required prior to the course:

Command-line usage of the classroom operating system, either MS-DOS or UNIX
Use of an available text editor (for example, Notepad or VI)
Use a WWW (World Wide Web) browser (for example, Netscape Navigator or MS Internet Explorer)

Highly recommended prior to course:

Programming experience with a procedural language, such as C or FORTRAN
Helpful to have prior to the course:
Programming experience with an object-oriented programming language, such as C++, Objective C, or Smalltalk.
Experience with object-oriented analysis and design

Course Objectives:

Upon completion of this course, a student will be able to write standalone applications and applets:

using the Java programming language
using object-oriented features, such as ordinary inheritance, as well as abstract classes, and interfaces
using method and data modifiers to control access
handling exceptions and creating exception classes
with graphical user interfaces, using Java's AWT
using the Java 1.1 delegation event model to handle mouse input, text, window, and menu events
