- A standard that lets you specify a unique label for the set of element names defined by a DTD. A document using that DTD can be included in any other document without having a conflict between element names. The elements defined in your DTD are then uniquely identified so that, for example, the parser can tell when an element
<name>should be interpreted according to your DTD rather than using the definition for an element <name>in a different DTD. The area of a program in which particular identifiers are visible. Java uses packages to provide namespaces, and its visibility rules - private, package, protected, public - variously contain identifiers within namespaces.

- A mechanism that allows a component to be customized without the need to access or change the component's source code. A container implements the component's naming environment and provides it to the component as a JNDI naming context. Each component names and accesses its environment entries using the
java:comp/envJNDI context. The environment entries are declaratively specified in the component's deployment descriptor. - Browse Related Terms: application client, application client container, callback methods, Component, component contract, component-managed sign-on, container, Enterprise JavaBeans (EJB), life cycle (J2EE component), naming environment, Sandbox, security permission, security permission set, software reuse, Web container

A constructor that takes no arguments. By default, all classes without an explicit constructor have a default no-arg constructor with
publicaccess. Its role is purely to invoke the no-arg constructor of the immediate super class.- Browse Related Terms: anonymous class, API, application programming interface (API), core class, Instance, instantiation, JFC, NEW, new operator, no-arg constructor, non-static nested class, object construction, search path, throw, type

- The process of removing redundancy by modularizing, as with subroutines, and of removing superfluous differences by reducing them to a common denominator. For example, line endings from different systems are normalized by reducing them to a single new line, and multiple whitespace characters are normalized to one space.
