Advanced Java Programming
Private Training

Course Summary

A company’s commitment to Java as a development language for internal applications or customer products means that eventually programmers will need to develop knowledge and skills beyond those learned in a basic Java course. Most production programs will need to interface with technologies such as XML, threading, and networking.

This intensive, hands-on course explores advanced Java 5.0 Standard Edition language features and packages. Students will learn to parse XML documents using the JAXP API. Multi-threaded applications will be covered in detail including concepts such as deadlocks and race conditions. Students will also learn how to utilize more advanced I/O capabilities with object serialization and low-level file I/O with the java.nio package. Client/server applications will be written utilizing both the java.net and java.rmi packages. Additional topics on JNI, performance tuning, and advanced RMI are included as appendices for further study.

Audience
Java programmers who wish to increase their depth of knowledge in Java programming and explore the uses of the various advanced packages.
Course Length
3 Days
Prerequisites
Intermediate Java Programming or equivalent experience is required.

Objectives

Access XML content with the Java API for XML Processing (JAXP).

Use threads to improve performance of Java programs.
