Introduction to Java

Length: 4 days
CourseID: introJava

Prerequisites:

Participants should have developed software in at least one other modern language. Familiarity with OO methodology is helpful. A background in C or C++ is extremely helpful.

Overview:

The Java programming language is the basis for scalable J2EE applications. This class introduces the basic components of Java Development. This is a hands-on learning experience, with each student developing many full life-cycle applications. Student will walk away with an understanding of how Java is developed and a good introduction to very common components of the language.

Objectives:

Learn the Java Programming Language

Build stand-alone java applications

Build Looping applications with Java

Design Java applications within Packages

Design well written code

Design Object Oriented applications

Design applications with Java Interfaces

Implement Polymorphism using Classes and Interfaces
