OL304: Introduction to Programming in Java

Description:

This course covers the basics of programming using the Java programming language. You will learn about variables, data types and operators and will practice using them. You will be introduced to arrays, flow-control, exception handling and differing data structures and practice applying what you've learned through hands-on exercises. You will be introduced to object-orientation, learning about classes and inheritance and practicing making use of these object-oriented features.

This hands-on course is composed of comprehensive lectures, practical project illustrations, and independent programming sessions. Prior to this course an understanding of computer logic and information technology is essential.

Objectives:

At the end of the course, participants will be able to:

1. Use the basic Java language syntax and constructs.
2. Differentiate between different types of Java applications.
3. Understand the main components and features of Java 2.
4. Understand the use of arrays and data structures.
5. Implement object-oriented concepts using Java.
6. Write simple Java programs.

Audience:

This course is designed for those who may have programmed before or who have studied some compiled programming languages, but don't program on a daily basis, who wish to develop their understanding and use of objects, methods, arrays, and classes.

Prerequisites:

Understanding of computer logic and information technology is essential.

Duration:    4 days
