Java

PowerDesigner supports the modeling of Java programs including round-trip engineering.

For information specific to modeling for Java in the Eclipse environment, see Core Features Guide > Modeling with PowerDesigner > The PowerDesigner Plugin for Eclipse.

• Java Public Classes
  Java allows the creation of multiple classes in a single file but one class, and only one, has to be public.
• Java Enumerated Types (Enums)
  Java 5 supports enumerated types. These replace the old typesafe enum pattern, and are much more compact and easy to maintain. They can be used to list such collections of values as the days of the week or the suits of a deck of cards, or any fixed set of constants, such as the elements in a menu.
• JavaDoc Comments
  Javadoc is a tool delivered in the JDK that parses the declarations and documentation comments in a set of Java source files and produces a corresponding set of HTML pages describing model objects.
• Java 5.0 Annotations
  PowerDesigner provides full support for Java 5.0 annotations, which allow you to add metadata to your code. This metadata can be accessed by post-processing tools or at run-time to vary the behavior of the system.
• Java Strictfp Keyword
  Floating-point hardware may calculate with more precision and with a greater range of values than required by the Java specification. The strictfp keyword can be used with classes or operations in order to specify compliance with the Java specification (IEEE-754). If this keyword is not set, then floating-point calculations may vary between environments.
• Enterprise Java Beans (EJBs) V2
  The Java TM 2 Platform, Enterprise Edition (J2EE TM) is a Java platform that defines the standard for developing multi-tier enterprise applications. J2EE simplifies enterprise applications by basing them on standardized, reusable modular components, it provides a complete set of services to those components, and handles many details of application behavior automatically without complex programming.
• Enterprise Java Beans (EJBs) V3
  The specification for EJB 3.0 attempts to simplify the complexity of the EJB 2.1 architecture by decreasing the number of programming artefacts that developers need to provide, minimizing the number of required callback methods and reducing the complexity of the entity bean programming model and the O/R mapping model.
• Java Servlets
  Servlets are programs that help in building applications that generate dynamic Web pages (HTML, XML). Servlets are a Java-equivalent of the CGI scripts and can be thought of as a server-side counterpart to the client-side Java applets.
• Java Server Pages (JSPs)
  Java Server Page (JSP) is an HTML Web page that contains additional bits of code that execute application logic to generate dynamic content.
• Generating Java Files
  You generate Java source files from the classes and interfaces of a model. A separate file, with the file extension .java, is generated for each class or interface that you select from the model, along with a generation log file. You can only generate Java files from one model at a time.
• Reverse Engineering Java Code
  You can reverse engineer files that contain Java classes into an OOM. For each existing class in a Java file, a corresponding class is created in the OOM, with the same name and containing the same information.
