Java Programming Course

This course emphasizes becoming productive quickly as a Java application developer. The course quickly covers the Java 5.0 language syntax and then moves into the object-oriented features of the language. Students will then use several of the provided API packages, such as I/O streams, collections, Swing GUI programming, threads, and accessing a database with JDBC. The course ends with a chapter on performance tuning with hints and best practices for writing efficient applications. Appendices on sockets, regular expressions and J2EE are also available for further study.

Audience: Programmers moving to object-oriented programming using Java.

Professional programming experience in C, C++ or C# is required. Knowledge of Object-Oriented concepts is also required.
