nTier's intermediate Java training course teaches programming in the Java language – the Java 2 Standard or J2SE platform. It is intended for students with previous Java experience or training, who already know the fundamentals of the Java architecture and basic procedural programming. This course provides in-depth coverage of object-oriented concepts and how to apply them to Java software design and development. The latter part of the course moves key parts of the J2SE Core API, including collections, exception-handling, logging, streams, and object serialization.
The course software also includes an optional overlay of workspace and project files to support use of the Eclipse IDE in the classroom. (This requires that the instructor be experienced in use of Eclipse and able to walk students through basic tasks in the IDE.) (Otional)This revision of the course begins migration from Java 1.4 to Java 5.0: it continues to focus on the 1.4.2 SDK and language, but highlights missing features and areas that are improved in the 5.0 JDK and language. It includes two code examples which will of course not build in the 1.4.2 environment, but work in 5.0 and offer examples of emerging Java-5.0 coding practices.
We also offer Introduction to Java training and Advanced Java training.
Chiefly, learn to program effectively in the Java language.
Understand Java as a purely object-oriented language, and implement software as
systems of classes.
Implement and use inheritance and polymorphism, including interfaces and abstract
classes.
Design appropriate exception handling into Java methods.
Use the standard logging API to write diagnostic information at runtime.
Understand the structure of streams in Java, and learn how to use streams to
manage file I/O.
Learn how to use Java Serialization to internalize and externalize potentially complex
graphs of objects.
Intermediate Java Training Prerequisites
Students must be able to write, compile, test, and debug simple Java programs, using structured programming techniques, strong data types, and flow- control constructs such as conditionals and loops. NT103 or at least 6 months of Java experience is recommended.
