  2. Java Design Patterns


    This Java Patterns course reviews common and emerging patterns specific to Java SDK and EE development. You’ll learn the depth and evolution of pattern-based techniques in Java,

    In design patterns, the responsibility of each component is identified by role.

    The conventions of design pattern documentation make it easier for development teams to communicate their programming intentions and provide a reference point for the entire Java development community.


    Delegates will learn how to

    • Dinstinguish between Java EE 5 and Java EE 6 pattern-based features.
    • Implement relevant patterns in each tier of the Java EE environment.
    • Re-factor code to improve inter-tier communications.
    • Relate pattern-based development to an implementation architecture.
    • Apply object-oriented pronciples and design guidelines.
    • Implement well-known patterns to Java-specific code problems.
