A group of types. Packages are declared with the
packagekeyword.A named grouping of classes and interfaces that provides a package namespace. Classes, interfaces and class members without an explicit

A style of programming in which statements are not necessarily executed in an ordered sequence but in parallel. Parallel programming languages make it easier to create programs that are designed to be run on multi-processor hardware, for instance. Java's thread features support a degree of parallel programming.

- An entity that consists of DTD specifications, as distinct from a general entity. A parameter entity defined in the DTD can then be referenced at other points, thereby eliminating the need to recode the definition at each location it is used.

- A module that reads in XML data from an input source and breaks it into chunks so that your program knows when it is working with a tag, an attribute, or element data. A nonvalidating parser ensures that the XML data is well formed but does not verify that it is valid. See also validating parser.

The Personal Digital Assistant Profile (PDAP) is a Java ME profile specification designed for small platforms such as PalmOS devices. You can think of PDAs as being larger than mobile phones but smaller than set-top boxes. PDAP is built on top of CLDC and will specify user interface and persistent storage APIs. PDAP is currently being developed using the Java Community Process (JCP).
