Highlights:
Course Description
This intense five-day course begins with a discussion of why Java has become so popular and ends with the student writing a fully-functional chat program that uses Java threads, sockets, streams and GUI programming.
 Prerequisites
This course is designed for developers who want to learn the Java programming language and have experience in other languages like C, COBOL, Visual Basic, Fortran, and so on.
At course completion
After taking this class, students will be able to develop object oriented programs in Java. Topics covered include multi-threading, Swing GUI development, creating socket and TCP/IP connections, I/O, interfaces, and object-oriented concepts.
