Java/Java Packages.Htm Copyright © Tutorialspoint.Com
JJAAVVAA -- PPAACCKKAAGGEESS http://www.tutorialspoint.com/java/java_packages.htm Copyright © tutorialspoint.com Packages are used in Java in order to prevent naming conflicts, to control access, to make searching/locating and usage of classes, interfaces, enumerations and annotations easier, etc. A Package can be defined as a grouping of related types classes, interfaces, enumerationsandannotations providing access protection and name space management. Some of the existing packages in Java are:: java.lang - bundles the fundamental classes java.io - classes for input , output functions are bundled in this package Programmers can define their own packages to bundle group of classes/interfaces, etc. It is a good practice to group related classes implemented by you so that a programmer can easily determine that the classes, interfaces, enumerations, annotations are related. Since the package creates a new namespace there won't be any name conflicts with names in other packages. Using packages, it is easier to provide access control and it is also easier to locate the related classes. Creating a package: While creating a package, you should choose a name for the package and include a package statement along with that name at the top of every source file that contains the classes, interfaces, enumerations, and annotation types that you want to include in the package. The package statement should be the first line in the source file. There can be only one package statement in each source file, and it applies to all types in the file. If a package statement is not used then the class, interfaces, enumerations, and annotation types will be placed in the current default package. -
Quick Start Guide for Java Version 5.0
Quick Start Guide for Java Version 5.0 Copyright © 2020 Twin Oaks Computing, Inc. Castle Rock, CO 80104 All Rights Reserved Welcome CoreDX DDS Quick Start Guide for Java Version 5.0 Nov 2020 Welcome to CoreDX DDS, a high-performance implementation of the OMG Data Distribution Service (DDS) standard. The CoreDX DDS Publish-Subscribe messaging infrastructure provides high-throughput, low-latency data communications. This Quick Start will guide you through the basic installation of CoreDX DDS, including installation and compiling and running an example Java application. You will learn how easy it is to integrate CoreDX DDS into an application. This Quick Start Guide is tailored for Java applications, and the examples differ slightly for other languages. Installation First things first: get CoreDX DDS onto your development system! Here’s what you need to do: 1. Once you have obtained CoreDX DDS from Twin Oaks Computing (or from the Eval CD), unpack the appropriate distribution for your machine somewhere on your system. We’ll refer to this directory throughout this guide as COREDX_HOME. For example, on a UNIX system this command will extract the distribution into the current directory: gunzip –c coredx-5.0.0-Linux_2.6_x86_64_gcc5-Release.tgz | tar xf – CoreDX DDS is available for multiple platform architectures, and multiple platform architectures of CoreDX DDS can be installed in the same top level (COREDX_TOP) directory. The directory structure under COREDX_TOP will look like: 2. If you are using an evaluation copy of CoreDX DDS, follow the instructions you received when you downloaded the software to obtain an evaluation license. -
Importance of DNS Suffixes and Netbios
Importance of DNS Suffixes and NetBIOS Priasoft DNS Suffixes? What are DNS Suffixes, and why are they important? DNS Suffixes are text that are appended to a host name in order to query DNS for an IP address. DNS works by use of “Domains”, equitable to namespaces and usually are a textual value that may or may not be “dotted” with other domains. “Support.microsoft.com” could be considers a domain or namespace for which there are likely many web servers that can respond to requests to that domain. There could be a server named SUPREDWA.support.microsoft.com, for example. The DNS suffix in this case is the domain “support.microsoft.com”. When an IP address is needed for a host name, DNS can only respond based on hosts that it knows about based on domains. DNS does not currently employ a “null” domain that can contain just server names. As such, if the IP address of a server named “Server1” is needed, more detail must be added to that name before querying DNS. A suffix can be appended to that name so that the DNS sever can look at the records of the domain, looking for “Server1”. A client host can be configured with multiple DNS suffixes so that there is a “best chance” of discovery for a host name. NetBIOS? NetBIOS is an older Microsoft technology from a time before popularity of DNS. WINS, for those who remember, was the Microsoft service that kept a table of names (NetBIOS names) for which IP address info could be returned. -
Bigraphical Domain-Specific Language (BDSL): User Manual BDSL Version: V1.0-SNAPSHOT
>_ Interpreter CLI BDSL BDSL User Manual BDSL v1.0-SNAPSHOT 1 Bigraphical Domain-specific Language (BDSL): User Manual BDSL Version: v1.0-SNAPSHOT Dominik Grzelak∗ Software Technology Group Technische Universit¨at Dresden, Germany Abstract This report describes Bigraphical DSL (BDSL), a domain-specific language for reactive systems, rooted in the mathematical spirit of the bigraph theory devised by Robin Milner. BDSL is not only a platform-agnostic programming language but also a development framework for reactive applications, written in the Java program- ming language, with a focus on stability and interoperability. The report serves as a user manual mainly elaborating on how to write and execute BDSL programs, further covering several features such as how to incorporate program verification. Moreover, the manual procures some best practices on design patterns in form of code listings. The BDSL development framework comes with a ready- to-use interpreter and may be a helpful research tool to experiment with the underlying bigraph theory. The framework is further in- tended for building reactive applications and systems based on the theory of bigraphical reactive systems. This report is ought to be a supplement to the explanation on the website www.bigraphs.org. The focus in this report lies in the basic usage of the command-line interpreter and mainly refers to the features available for the end-user, thus, providing a guidance for taking the first steps. It does not cover programmatic implementation details in great detail of the whole BDSL Interpreter Framework that is more suited to developers.

Moscow ML .Net Owner's Manual
Moscow ML .Net Owner's Manual Version 0.9.0 of November 2003 Niels Jørgen Kokholm, IT University of Copenhagen, Denmark Peter Sestoft, Royal Veterinary and Agricultural University, Copenhagen, Denmark This document describes Moscow ML .Net 0.9.0, a port of Moscow ML 2.00 to the .Net platform. The focus is on how Moscow ML .Net differs from Moscow ML 2.0. Three other documents, the Moscow ML Owner’s Manual [7], the Moscow ML Language Overview [5] and the Moscow ML Library Documentation [6] describe general aspects of the Moscow ML system. Moscow ML implements Standard ML (SML), as defined in the 1997 Definition of Standard ML, including the SML Modules language and some extensions. Moreover, Moscow ML supports most re- quired parts of the SML Basis Library. It supports separate compilation and the generation of stand-alone executables. The reader is assumed to be familiar with the .Net platform [2].

Investigating the Feasibility of an MPI-Like Library Implemented in .Net Using Only Fully Managed Code
Investigating the Feasibility of an MPI-like Library Implemented in .Net Using Only Fully Managed Code Daniel Holmes MSc in High Performance Computing The University of Edinburgh Year of Presentation: 2007 Abstract The .Net development platform and the C# language, in particular, offer many benefits to programmers including increased productivity, security, reliability and robustness, as well as standards-based application portability and cross-language inter-operation. The Message Passing Interface (MPI) is a standardised high performance computing paradigm with efficient, frequently-used implementations in many popular languages. A partial implementation of McMPI, the first MPI-like library to be targeted at .Net and written in pure C#, is presented. It is sufficiently complete to demonstrate typical application code and to evaluate relative performance. Although the effective bandwidth for large messages (over 100 Kbytes) using 100Mbit/s Ethernet is good, the overheads introduced by .Net remoting and object serialisation are shown to result in high latency and to limit bandwidth to 166Mbit/s when using a 1Gbit/s Ethernet interconnection. A possible resolution that still uses pure C#, i.e. using .Net sockets, is proposed but not implemented. Contents Chapter 1.
