java面向特定群体的健康管理平台设计与实现毕业设计英文文献翻译内容摘要：

main method must accept an array of String objects. By convention, it is referenced as args although any other legal identifier name can be used. Since Java 5, the main method can also use variable arguments, in the form of public static void main(String... args), allowing the main method to be invoked with an arbitrary number of String arguments. The effect of this alternate declaration is semantically identical (the args parameter is still an array of String objects), but allows an alternative syntax for creating and passing the array. The Java launcher launches Java by loading a given class (specified on the mand line or as an attribute in a JAR) and starting its public static void main(String[]) method. Standalone programs must declare this method explicitly. The String[] args parameter is an 第 6 页 共 11 页 array of String objects containing any arguments passed to the class. The parameters to main are often passed by means of a mand line. Criticism of Java A number of criticisms have been leveled at Java programming language for various design choices in the language and platform. Such criticisms include the implementatio n of generics, the handling of unsigned numbers, the implementation of floatingpoint arithmetic, and security vulnerabilities. Class libraries Java Platform and Class libraries diagram Java libraries are the piled byte codes of source code developed by the JRE implementor to support application development in Java. Examples of these libraries are: The core libraries, which include: Collection libraries that implement data structures such as lists, dictionaries, trees, sets, queues and doubleended queue, or stacks XML Processing (Parsing, Transforming, Validating) libraries Security Internationalization and localization libraries The integration libraries, which allow the application writer to municate with external systems. These libraries include: The Java Database Connectivity (JDBC) API for database access Java Naming and Directory Interface (JNDI) for lookup and discovery RMI and CORBA for distributed application development JMX for managing and monitoring applications User interface libraries, which include: The (heavyweight, or native) Abstract Window Toolkit (AWT), which provides GUI ponents, the means for laying out those ponents and the means for handling events from those ponents The (lightweight) Swing libraries, which are built on AWT but provide (nonnative) implementations of the AWT widgetry APIs for audio capture, processing, and playback 第 7 页 共 11 页 A platform dependent implementation of Java Virtual Machine (JVM) that is the means by which the byte codes of the Java libraries and third party applications are executed Plugins, which enable applets to be run in Web browsers Java Web Start, which allows Java applications to be efficiently distributed to endusers across the Inter Licensing and documentation. DocumentationMain article: Javadoc Javadoc is a prehensive documentation system, created by Sun Microsystems, used by many Java developers. It provides developers with an anized system for documenting their code. Javadoc ments have an extra asterisk at the beginning, . the tags are /** and */, whereas the normal multiline ment tags ments in Java and C are set off with /* and */. Sun has defined and supports four editions of Java targeting different application environments and segmented many of its APIs so that they belong to one of the platforms. The platforms are: Java Card for smartcards. Java Platform, Micro Edition (Java ME) — targeting environments with limited resources Java Platform, Standard Edition (Java SE) — targeting workstation environmentJava Platform, Enterprise Edition (Java EE) — targeting large distributed enterprise or Inter environments. The classes in the Java APIs are anized into separate groups called packages. Each package contains a set of related interfaces, classes and exceptions. Refer to the separate platforms for a description of the packages available. The set of APIs is controlled by Sun Microsystems in cooperation with others through the Java Community Process program. Companies or individuals participating in this process can influence the design and development of the APIs. This process has been a subject of controversy. Sun also provided an edition called PersonalJava that has been superseded by later, standardsbased Java ME configurationprofile pairings. JSP Profile JSP (Java Server Pages) is initiated by Sun Microsystems, Inc., with many panies to participate in the establishment of a dynamic web page technical standards. JSP technology somewhat similar to ASP technology, it is in the traditional HTML web page document (*. 第 8 页 共 11 页 htm, *. html) to insert the Java programming paragraph (Scriptlet) and JSP tag (tag), thus JSP documents (*. jsp). Using JSP development of the Web application is crossplatform that can run on Linux, is also available for other operating systems. JSP technology to use the Java programming language prepared by the category of XML tags and scriptlets, to produce dynamic pages package processing logic. Page also visit by tags and scriptlets exist in the services side of the resources of logic. JSP page logic and web page design and display separation, support reusable ponentbased design, Webbased application development is rapid and easy. Web server in the face of visits JSP page request, the first implementation of the procedures of, and then together with the results of the implementation of JSP documents in HTML code with the return to the customer. Insert the Java programming operation of the database can be reoriented websites, in order to achieve the establishment of dynamic pages needed to and Java Servlet, is in the implementation of the server, usually returned to the client is an HTML。
