A Businessperson's Guide to Web Development
Java is a general computer programming language developed by Sun Microsystems. Originally called "Oak", by its inventor James Gosling, Java was designed with several innovative features. These include a language that is entirely object oriented, and the ability to write an application once and move it to virtually any platform.
InnovationsThe benefits of object-oriented programming are not necessarily obvious to non-programmers. Essentially what this means to managers is that code written in Java will be easier to maintain and reuse in the long run. The downside is that object-oriented programming requires better planning from the beginning of a project, and may increase the amount of initial development time a project requires. For this reason alone, Java is rarely a good choice for small projects requiring a fast turnaround time.
The second innovation that Java provides, platform neutrality, is perhaps the greatest reason for its wide acceptance. The fact that Java was originally intended a language for writing device controllers for items such as garage openers and microwave ovens is the key reason for this. In practice, however, this ability has been more useful in writing enterprise class business applications, where mission critical software may be required to run on a variety of platforms over its lifetime. Theoretically at least, once compiled, a Java binary should be able to run on any machine that also has a piece of software called a Java Virtual Machine. In reality, this is not always the case. However, more often than not Java does succeed in this regards, whereas this is impossible with an application written in a language such as C++.
Java in Web DevelopmentIn terms of web development, Java is frequently used in two ways. Most commonly Java is used to write server-side web applications using two technologies: JSPs and servlets. Using Java in this capacity is a good choice for complex applications, that will have large numbers (~1000+) of concurrent users, and will be developed by a team of programmers. Less complex projects, with fewer concurrent users may have better outcomes when developed in procedural scripting languages such as PHP or PERL.
Origin and GrowthLike many recently developed computer languages, Java borrows much of its language design from C/C++. For that reason, many programmers who are proficient in those languages have leaned Java, and provide a large pool of qualified developers. Java has gained additional ground as a first language, as it is generally simpler to master than C++, another commonly used programming language.
