Java is a completely secure, robust, portable and powerful object-oriented programming language and platform. Java is widely used for developing mobile applications, web applications, databases, etc. Above all it provides a software platform that runs on top of other hardware based platforms. The Java platform comprises of two components including the Java Virtual Machine and the Java Application Programming Interface. The API consists of packages and interfaces that provide many useful features.
Programs commonly created using Java are applications and applets. Applications are standalone programs where as applets are similar to applications but they don’t run independently. Applets run within the web browser compatible with the Java platform. Some common Java applications are server and servlet. Server is a special kind of application that serves the client on network. Servlet is a specialized program that runs on server side. Java Servlets are commonly used for building interactive web applications. Before beginning the object-oriented programming, a Java programmer should understand some basic Java concepts. A Java programmer should be familiar with the fundamental concepts like object, message, class, inheritance, and interface. The most important factor is that the programmer should be capable of translating these concepts into code.
A Java programmer can use specific Java editors for purpose of smooth programming. As most of the Java editors have a “Preferences” page, it is essential for a programmer to setup the tool according to the requirements. Tool setup reduces the problems that occur during programming and increase the efficiency of the programmers. A Java programmer can adopt a customized coding standard but it is subtle to stick to the coding conventions provided by Sun Microsystems. A Java programmer should follow the Naming Standards for an application. Names are mandatory for classes, methods, variables, interfaces, packages, .jsp and .html files, style sheets, script files, configuration files, etc. Since Java applications use a database, naming standards are obligatory for databases, tables, views, stored procedures, etc. Naming Standrads makes the application less complicated simpler to maintain. It simplifies the concept and makes the application easier to pick the name for a new item. The prolific skill of a Java programmer should be error handling. A programmer must handle the errors in a cognizant and standardized way using chained exceptions. The Java programmer must perform a unit test of the projects of all its methods as well as its business functionality irrespective of the involved classes and methods. Unit-testing is conducted from back-end to the front-end including all client programs. The naming standards should be in place for the unit test programs. The final step is the bug tracking. It is implemented to verify the proper functionality of the project. The bugs can be tracked by manually operating the program or by using bug-tracking tools.
