Course Description

This Java training course 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. Early in the class the concept of objects is introduced so that later concepts can be discussed from the perspective of object orientation. The class is based on Java 1.5 and 1.6, but most concepts would apply in 1.4 as well.
Course Length: 5 Days
Course Tuition: $2090 (US)


This course is intended for students without an extensive programming background. If you have a lot of object-oriented programming experience in a language such as C# or C++, you may want to consider our Java Programming Training for Experienced Programmers class instead.
