About this class

Java's unique architecture enables programmers to develop a single application that can run across multiple platforms seamlessly and reliably. In this hands-on course, you gain extensive experience with Java and its object-oriented features. You learn to create robust console and GUI applications and store and retrieve data from relational databases.

Hands-on Training

A series of hands-on exercises provides experience creating Java applications. Through an ongoing case study, you design and build an intricate desktop application modelled on a well-known Web site. Exercises include:

• Developing an object-oriented model with UML notation
• Creating Java objects and calling their methods
• Structuring data with the Java collections API
• Creating portable GUIs with Swing components
• Adding event handling to GUIs
• Retrieving data from a relational database with JDBC

Who will the lesson benefit?

Anyone developing Java applications. Previous experience with a programming language such as C, Pascal or COBOL is assumed. Familiarity with Web technologies and object concepts is helpful.
