Java:  Introduction

Duration:   5 days

Participants:   Application developers interested in learning the introductory topics of the Java 2 platform.

Objectives:   Upon successful completion of this course you will be able to: -  Define and use classes, abstract classes, interfaces, nested classes, and anonymous classes. -  Develop Java code that performs stream I/O and network functions. -  Recognize Java's strengths and weaknesses. -  Recognize the new and advanced features in JDK 1.2 (a.k.a. Java 2), including Swing, code signing, Remote Method Invocation (RMI), Java Native Interface (JNI), and Java Beans. -  Understand the object oriented features of Java, including encapsulation, inheritance, and polymorphism. -  Use exception handling. -  Use Java syntax, including expressions, statements, class declarations, scope, as well as all of the Java keywords, and primitive data types. -  Use the following control structures: while, do-while, and for loops, as well as if-else and switch statements.

Overview:   This course teaches you to program in Java using the various Java language constructs and good OO Design. Whjere appropriate, industry supported design patterns are presented.

Prerequisites:   Some programming experience and knowledge of object oriented systems.

Format:   Lecture and discussion with hands-on exercises.
