unit test
Unit testing is a separate work unit. In Java applications, "independent work unit" often refers to a method (but not always). As compared, integrated testing and reception tests check how multiple components interact. A work unit is a task that does not depend on any other task. (Excerpted from "JUnit In Action" in Chinese)
2.
frame
The frame is a semi-finished product of an app. The framework provides a multiple common structure that can be shared between applications. Developers integrate the frame into their own app and extend to meet their specific needs. The difference between the framework and kit is that the framework provides a consistent structure, not just a set of tool classes. (Excerpted from "JUnit In Action" in Chinese)
XSL
EXTENSIBLE StyleSheet Language (Extensible Style Language), it can change and convert data in XML format to another XML format. It provides a defined style sheet that can complete conversions in different formats via this structure. In order to avoid that the data must be changed because of a different expression method, XSL makes data or document content and representation forms. The method it uses can be compared with a small program that converts data into other formats with Java, and a standard interface is also provided.
Name space
NameSpace is a mapping relationship between an element prefix and a URI (Unified Resource Identifier) that can be used to handle the namespace conflict, define the data structure that allows the parser to process conflicts. XML namespace recommendation criteria define mechanisms that specify these names, this mechanism relies on URI to complete tasks, and the details are described later. The namespace is composed of an XML element, such as
DTD
Document Type DEFINITION (Document Type Definition), which establishes a set of rules for an XML document or document collection. It itself is not an independent technical specification, but part of the specification, the document type declaration in the XML document can either a marker constraint or an external document with a tag constraint. The sum of these two constraints is DTD. It specifies how the XML document is built.
Pi
Processing Instruction, indicating that the application performs some specific tasks in XML. Its format is , It can only be part of the XML standard processing instruction set of the parser can identify. Sometimes it is also used to communicate information, which can be used to help perform parsing. In this case, there is a keyword that can be executed as a processing instruction.
Xml
The abbreviation of Extentsible Markup Language is a generic language for defining other languages, and its predecessor is SGML (standard universal tag language). It does not have a tag set, and there is no grammatical rule, but it has a syntax rule. Any XML document must be a well-final, that is, a Well-Formed, that is, each open tag must have a matching end tag, and may not contain the subset of upside down, and in the statement Should meet the requirements of technical specifications. The XML document can be valid (Valid), but it is not a certain requirement. The so-called valid document refers to a document that meets its document type definition (DTD). If a document meets a mode (Schema) rules, this document is "Schema Valid". Hibernate
Hibernate is an O / R Mapping of an open source, which makes a lightweight object package for JDBC, allowing Java programmers to operate the database as you want to use objects to manipulate the database.

Open closed method
Software entities should be scalable, but unmodified (Software Entities Should Be Open for Extension, Yet Closed for Modification), referred to as OCP, this rule is the most important rule in OO, and its meaning is that we should be able to modify software The source code of the entity can change the behavior of the software entity, which is in line with the rules that the highest level of reusability and maintainability are.

Idl

AWT
Abstract Window Toolkit (Abstract Window Toolkit), the first generation of Java GUI kits, now basically no use of components, has been replaced by swing, but swing is extended AWT. AWT also contains a lot of content that now is still frequently used, such as event processing and listening, layout manager, etc. AWT is also part of JFC.
Corba
CommON Object Request Broker Architecture (Public Object Request Agent), is a set of standards for defining "distributed object system", which are set by OMG (Object Menagement Group) as initiating and standard. The purpose of CORBA is to define a set of protocols that meet this protocol can interact with each other, whether they are written, regardless of what kind of machines and operating systems they run.
Iiop
Internet Inter-ORB Protocol (Internet Internal Object Request Agent Protocol), Java enables programs to implement interoperability with other languages CORBA.
JNDI
Java Naming and Directory Interface (Java Names, Directory Service Interface), Technical Specifications for Directory and Naming Services in Java, similar to JDBC, which consists of API and SPI.

Di
Dependency Injection, that is, the dependency between components is determined by the container in the runtime, that is, the container is dynamically injected some dependencies into the component. The goal of relying on the injection is not to bring more functions to the software system, but to improve the probability of component reuse, and build a flexible and scalable platform for the system. By relying on the injecting mechanism, we only need to pass a simple configuration, without any code, you can specify the resources you need, complete your own business logic, not where the specific resource comes from, from who is implemented. (The above is also taken from the Spring Development Guide of Xia Zhen). DI and IOC are synonymous.
IOC
Inversion of Control, the relationship between the container control program, not the traditional implementation, directly controlled by the program code, the control is transferred from the application code to the external container, the transfer of control, is a so-called reverse. (Spring Development Guide, which is taken from Xia Zhen)
L10n

Java Virtual Machine (Java Virtual Machine), is a fictional computer that is implemented by simulating various computer functions on actual computers. Java virtual machines have their own perfect hardware architecture, such as processors, stacks, registers, etc., have corresponding instruction systems. The JVM blocks information related to the specific operating system platform, so that the Java program only needs to generate the target code (bytecode) running on the Java virtual machine, you can operate on a variety of platforms. When the Java Virtual Machine is actually ultimately explained to the machine instruction execution on the specific platform.
