Introduction to Java Training for New Programmers (5 days)

Introduction to Java Programming Course Overview

This Java training course is intended for students without an extensive programming background. It covers most Java syntax elements, concentrating on fundamental and universally useful elements, while providing an overview of many more advanced elements. Students will learn to write useful Java classes, applying Object-Oriented concepts such as inheritance, and create Java programs that work with these classes.

The class introduces the concept of objects as one of the first topics, in order that the later concepts are covered with an OO perspective. The class is based on Java 1.5 and 1.6, but most concepts would apply in 1.4 as well.

Introduction to Java Programming Course Goals

• Learn how Java works.
• Understand the "write once, run anywhere" concept.
• Understand and learn how to create basic Java objects.
• Learn how to implement flow-control concepts in Java.
• Understand Java's package concept and create packages of Java classes.
• Understand Java arrays and write code to create and use arrays.
• Learn how to write Java classes using inheritance.
• Learn how to create and use interfaces.
• Understand and use the concept of polymorphism in an application
• Understand how Java's exception-handling mechanism works and learn how to apply exception-handling to Java applications.
• Understand and use inner classes.
• Learn how to use elements from the Java API library, including the Collections classes.

Introduction to Java Programming Course Prerequisites

Experience in the following areas is required:

• Some prior programming experience in a procedural or object-oriented language.
