关键词： 项目教学法   Java程序设计   模块   项目任务  

摘要： Java程序设计教学的目标，不仅要求学生掌握Java程序设计的基本理论，更要求学生能编写出符合实际需求的程序，使软件产品符合用户的使用习惯，在此教学中引入项目教学法较合适。如在“数据库编程”教学中，可选择“学生信息管理平台设计”这一项目，并设计“编写学生信息输入模块程序”、“编写学生信息查询模块程序”和“编写总控模块程序”三个任务，设计的任务和问题要照顾不同程度学生的需求。

关键词： 数据校验   Web应用   Javascript   Struts框架  

摘要： 数据校验就是为保证数据的完整性，用一种指定的算法对原始数据进行有效性验证。在任何一个基于Web的应用中，数据校验是安全进程的必需部分，程序逻辑要求用户提交需要校验的数据。一般采用两种方式来校验数据。一是在客户端校验，在数据提交到服务器之前进行。通常，这种校验使用运行在客户端浏览器内的Javascript完成。二是在服务器端校验。在执行对数据的任何操作之前，使用应用服务器支持的技术来完成校验。下面以userForm表单为例，介绍在开发基于Java的Web应用程序中使用的数据校验方法。

摘要： 介绍了在应用程序中调用SQL Server存储过程的方法,并给出了Java编程环境中的具体实现过程。

关键词： Matlab   Vrml   Java   虚拟现实工具箱  

摘要： 科学与工程领域经常涉足网络环境下的工程计算问题。Matlab具有很强的数值计算能力,而Vrml是最具潜力的网络三维图形建模语言,Java是目前普遍使用的网络应用开发工具。本文研究了通过Java把Matlab的计算结果利用Vrml来显示的途径,介绍的这些方法都能够将Matlab的运算能力、Java的网络开发功能与Vrml的三维网络显示能力很好地结合起来,实现三者的优势互补。由于各种方法各有所长,在实际应用中要根据具体问题和要求的不同进行合适的选择。

关键词： programmed instruction   collaborative peer tutoring   interteaching   Java training  

摘要： To fulfill part of the course requirements, 34 undergraduate students in two courses completed an online programmed instruction tutor as the first technical training exercise in a Java (TM) programming course designed for information systems majors. The tutor taught a simple JApplet program to display a text string within a browser window on the Web. Students in the first course next participated in a collaborative peer tutoring session, based on the JApplet program, followed by a lecture on the program and by successfully running the program on the Web. For the second course, the peer tutoring session was scheduled after the lecture and after successfully running the program. Students in both courses completed tests of far transfer ("meaningful learning") and software self-efficacy before using the tutor and on several subsequent occasions following that initial learning. Students in the second course also completed a 4-item scale to assess the development of classification and functionality knowledge regarding elements of the program. Students in both courses showed progressive improvement in all performance measures across the several assessment occasions. Students' positive ratings of the effectiveness of both the tutor and the collaborative peer tutoring supported the value of these learning experiences in a technical knowledge domain. The results of this study, based on student performance observed within the context of the classroom, show the importance of providing a range of synergistic learning experiences that culminate in a level of skill and confidence that prepares and motivates all students for advanced instruction in Java. They also show how to manage the instructional techniques in the classroom to accomplish that educational outcome. (c) 2007 Elsevier Ltd. All rights reserved.

关键词： PROGRAMMING languages (Electronic computers)   JAVA (Computer program language)   COMPUTER software   SOFTWARE engineering  

摘要： The article discusses the effort to expand the Java computer language's application capability into safety-critical where failure puts lives at risk in the U.S. Once implemented, this new profile will help enable software engineers to write Java programs with unprecedented levels of reliability. Safety-critical systems may involved supporting life or in tasks where mistake can imperil lives. The ideal language for safety-critical software would allow succinct implementation of the design.

关键词： Influenza   Java Program   Rift Valley Fever   Rift Valley Fever Virus   Sorting Operation  

摘要： Background: Viruses of the Bunyaviridae have segmented negative-stranded RNA genomes and several of them cause significant disease. Many partial sequences have been obtained from the segments so that GenBank searches give complex results. Sequence databases usually use HTML pages to mediate remote sorting, but this approach can be limiting and may discourage a user from exploring a database. Results: The VirusBanker database contains Bunyaviridae sequences and alignments and is presented as two spreadsheets generated by a Java program that interacts with a MySQL database on a server. Sequences are displayed in rows and may be sorted using information that is displayed in columns and includes data relating to the segment, gene, protein, species, strain, sequence length, terminal sequence and date and country of isolation. Bunyaviridae sequences and alignments may be downloaded from the second spreadsheet with titles defined by the user from the columns, or viewed when passed directly to the sequence editor, Jalview. Conclusion: VirusBanker allows large datasets of aligned nucleotide and protein sequences from the Bunyaviridae to be compiled and winnowed rapidly using criteria that are formulated heuristically.
