Introduction to Java for C++ Programmers

Course #W103

3 Days

Benefits

This hands-on course introduces the Java language to C++ programmers in a practical, tangible way. Students will create Java applets that can be taken away from the course and used as models for future work.

Target Student

Application programmers familiar with C++ and the concepts of object- orientation. It is assumed that students will be familiar with the Internet and with basic HTML.

Prerequisites

▪          Introduction to Object-Oriented Programming with C++ or equivalent experience.

▪          Introduction to Publishing on the World Wide Web with HTML (W002) or equivalent experience.
