Java

You will learn how to

• Write, compile and execute Java programs
• Build robust applications using Java's object-oriented features
• Create robust applications using Java class libraries
• Develop platform-independent (GUIs)
• Read and write data using Java streams
• Retrieve data from a relational database with JDBC

Course benefits
Organisations looking for ways to quickly build robust, cross-platform enterprise applications are turning to Java programming. Java's unique architecture permits programmers to develop a single application that can run across multiple platforms seamlessly and reliably.

This course provides extensive experience with Java and its object-oriented features. You use Java to create both console and GUI applications.

Who should attend
This course is valuable for anyone developing Java applications. Previous experience with a programming language is assumed. Familiarity with Web technologies and object concepts is helpful.

Hands-on training
A series of hands-on execises 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
• Extending Java classes for reusability
• Structuring data with the Java collections API
• Creating portable GUIs with Swing components
• Adding event handling to GUIs
• Reading, processing and writing to disk
• Retrieving data from a relational database with JDBC
