advanced Java programming

This course covers advanced object oriented techniques and algorithms with Java. It is an extremely practical course, developed and taught by consultants with many years' experience in OO design. When taught at your site, this modular course can be adapted to your situation and requirements. Included in the course are numerous examples and exercises, and comes with a reference text. After the course, we are able to offer reviews and mentoring to guide you in making the best use of the techniques.

Duration: 4 days

objectives

  • gain competence in Java's component model — Java Beans
  • learn how to dynamically invoke and configure components
  • develop essential skills to migrate components to a distributed environment
  • know the pitfalls and solutions of distributed and concurrent programming
  • be able to use relevant Java design patterns and idioms to solve common problems

target audience

The course is suitable for Java developers.

prerequisites

Ideally this training should be preceded by the course: design and develop Java applications.

Reflection

  • find the class
  • discover modifiers, fields, methods, constructors, and superclasses
  • find information on interfaces
  • runtime object creation
  • flexible component initialization
  • dynamic method invocation

Java Beans

  • client side Beans
  • server side Beans
  • existing Beans

JDBC

  • JDBC versus ODBC
  • JDBC driver types, JDBC-ODBC bridge
  • two tier versus three tier models
  • DriverManager
  • Driver
  • Connection
  • Statement
  • ResultSet
  • mapping SQL data types

Threads and concurrency

  • thread theory: philosophers at lunch
  • Runnable interface and the Thread class
  • critical sections, locks, synchronization

Distributed computing

  • overview of current technologies (J2EE, RMI, CORBA, DCOM)
  • RMI and ORBs
  • patterns for distributed components
  • defining interfaces to active objects
  • problems of building enterprise applications
  • adopting existing legacy applications into the universal C/S
  • structure
  • remote RMI interfaces
  • RMI clients, server, and registry

Patterns

  • MVC(Model View Controller)
  • Two-way link
  • Observer
  • Recursive Composite
  • State Delegation
  • Interface Decoupling

Servlets

  • advantages of Servlets over CGI
  • Servlet sessions
  • Servlet class hierarchy
  • Servlet interaction with the client

Review of other Java technologies

  • Java Naming and Directory Interface (JNDI)
  • Java Transaction Service (JTS)
  • Java Message Service (JMS)
  • Java in small memory spaces, eg PDAs

Please note, when taught at your site, this course is customizable. Modules can be adapted, removed, added from other courses, or even created.
