Java Application Development
Java is considered as the most powerful and secure high-level programming language and a platform. It is commonly used for object oriented programming in mobile application development, web applications, and etc. Java provides a software platform that runs only on top of other hardware based platforms. The Java platform has two components:
- The Java Virtual Machine (JVM)
- The Java Application Programming Interface (API)
The API is a collection of ready-made software components that provide many useful features. It contains the libraries of related classes called packages and interfaces.
The first requirement of Java Application Development is the tool setup. Most of the Java editors have a “Preferences” page where a programmer can setup the tools according to requirement. This helps reduce problems during programming and increase the efficiency of the developers. The coding standards depend on the programmer, but it is wise to follow the coding conventions provided by Sun Microsystems.
The most important criteria in Java development are the naming standards. Any item having a name should be extended by its corresponding naming standard. In Java names are required for classes, methods, variables, interfaces, packages, .jsp and .html files, style sheets, script files, configuration files, etc. Java applications use a database; so naming standards should also cover names for databases, tables, views, stored procedures, etc. the various reasons for deploying naming standards are:
- Naming Standards makes the application less complicated and simpler to maintain.
- It makes the application easier to pick the name for a new item.
- It deduces a name during search of an item.
- It simplifies the abstracts.
The crucial part of a Java application is the error handling. It is very much important to handle the errors in a sensible and standardized way. The good method for handling serious technical errors is to use chained exceptions. Logging is often used for logging errors and reports the performance data and other events like startup and shutdown.
The arrangements of most application are controlled by a set of parameters. Some parameters can be taken from a database, but is not always suitable because the parameters require the database setup to be in place before using it. The Java projects require a unit test 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.
