Finally chapter4 lists important Web sites for HTML, XML and JavaScript. The level of presentation is such that one can study the subject early on in oneseducation in programming. There is a balance between practical programming andthe underlying language. The book is ideally suited for use in lectures on Java andobject-oriented programming. The beginner will also benefit from the book. Thereference list gives a collection of textbooks useful in the study of the computerlanguage Java. There are a number of good textbooks for Java available [1], [2]. Forapplications of Java in science we refer to Tan Kiat Shi, W.-H. Steeb and YorickHardy [6] and Steeb [5]. Comprehensive introductions into JavaScript are given by[3] and [4]. The Web is an interlinked collection of living documents containing formatted text,images, and sound. These documents are organized into webspaces. A webspaceis typically structured around a home page with links to other pages or documentsboth in and outside of the webspace. A home page functions as a virtual meet-ing place in cyberspace for the exchange of information. We write a home page inHTML. There are many home pages with information about HTML and the World WideWeb, HTML is a language under construction. The continuing development ofHTML is conducted on the Web in an open process. New tools and techniques ap-pear frequently and are quickly spread throughout the community of Web authors. HTML is not a programming language and an HTML document is not a computerprogram. A computer program is a series of procedures and instructions applied,typically, to external data. An HTML document, however, is the data. The defini-tion of HTML specifies the grammar and syntax of markup tags that, when insertedinto the data, instruct browsers - computer programs that read HTML documents- how to present the document.
