Generics and Annotations
Descriere curs:
- Description: To explain what metadata is and how it can be used to provide annotation source to third-party tools and to outline generics in Java.
- Target audience: Programmers with an understanding of procedural programming concepts who want to learn Java and object-oriented programming; programmers proficient in another object-oriented programming language who want to move to Java; programmers experienced in the Java language who want to make the upgrade to Java SE 6.
- Estimated Duration: 180 Minutes
- Lesson Objectives: Java Programming with Java SE 6.0: Generics and Annotations
• identify the advantages and disadvantages of using generics in code, and outline how generics are used to make raw code type safe.
• specify the generic, type safe version of a given piece of legacy code.
• specify the code involved in building a generic class for a given scenario.
• specify the code required to declare a generic subclass, test generic object types, and cast a generic object.
• convert a given application's legacy code into a generic type safe equivalent.
• associate Java's retention policies and built-in annotations with their corresponding features and functionality.
• specify the code to annotate an overriding method, a deprecated method, and to suppress compiler warnings.
• specify the code to declare custom and meta-annotations.
• specify the code to inspect and represent a custom annotation, write an annotation processor, and run the processor against a set of annotations.
• create and implement a custom annotation for a given scenario.
