Templates in java 6

There are no templates in Java. The only thing that is comparable with templates are Java Generics. Java has generics which are similar but not exactly the same as templates.

There is no build in template mechanism in java. In stead they have generics. Moreover, ides have something called code templates e. You don't really need templates in Java. Templates are mainly useful when you need to have completely different types as a parameter that you know nothing about. In Java, all objects are virtual and inherit from one root object, and primitive types are defined much more clearly and casts work in a more sensical manner so there's really no point to it.

JavaServer Faces technology provides the tools to implement user interfaces that are easy to extend and reuse. Templating is a useful Facelets feature that allows you to create a page that will act as the base, or template , for the other pages in an application.

By using templates, you can reuse code and avoid recreating similarly constructed pages. Templating also helps in maintaining a standard look and feel in an application with a large number of pages. Table lists Facelets tags that are used for templating and their respective functionality. Defines a page composition that optionally uses a template. Content outside of this tag is ignored. The Facelets tag library includes the main templating tag ui:insert.

A template page that is created with this tag allows you to define a default structure for a page. A template page is used as a template for other pages, usually referred to as client pages. The example page defines an XHTML page that is divided into three sections: a top section, a left section, and a main section. The sections have style sheets associated with them. The same structure can be reused for the other pages of the application. The client page invokes the template by using the ui:composition tag.

In the following example, a client page named templateclient. A client page allows content to be inserted with the help of the ui:define tag. All rights reserved. You can write a single generic method declaration that can be called with arguments of different types.

Based on the types of the arguments passed to the generic method, the compiler handles each method call appropriately. Each type parameter section contains one or more type parameters separated by commas. A type parameter, also known as a type variable, is an identifier that specifies a generic type name. The type parameters can be used to declare the return type and act as placeholders for the types of the arguments passed to the generic method, which are known as actual type arguments.

A generic method's body is declared like that of any other method. Note that type parameters can represent only reference types, not primitive types like int, double and char.
