Java software development - Technology Means Life

A software development process is the systematic and structured approach to the development of a software product. It is infact, the overall process an organization needs to follow to manage the software project efficiently and as well these processes should be executed in a sequence to ensure the smooth flow of development. In the development cycle, quality and security should not be conciliated at the same time cost effective and time efficient methodologies have to be taken into consideration. Developing large number of software products without meeting the expectations of quality, cost flexibility, and timely delivery, effective process management seems to be missing which is very essential.

In the initial years of software development, the development was limited to few individuals. There creates problems and errors were common, quality was not maintained and it was very difficult to manage the system as it grow. At this point of time, to define the process of development gained its importance. Reliability, effectiveness, maintainability, quality, durability etc became decisive and the software developing organizations began to formulate a well defined software development process in Java for the successful implementation of the project. In software process, the huge size of the software product and the quality and complexity factors demands the disintegration of a project into manageable milestones for the development, testing and management. There are no hardcode rules or procedures for a process adoption. Every company defines or customizes its own set of processes for a successful project management. A clear process approach ensures that no step or activity is forgotten before a delivery or implementation, also it shows a clear direction towards the end product. The advantage of identifying the risks and alleviate the same by consecrating more or less time to the different stages finally contribute to efficient cost and time management.

A continually improving and adaptive process is required to incorporate latest challenging and changing requirements. This type of continually improving process model is called Evolutionary process models where the change of requirements and enhancements can be easily incorporated. Incremental model and spiral model are the main evolutionary models. Each of these models has its own impact on the software quality aspects. Identifying the appropriate one could help the organizations identify those underlying factors that meet their quality requirements. Telious has a set of proven evolutionary processes through which we could manage and measure software development progress effectively. With the implementation of disciplined process models we guarantee project delivery in right time backed by quality assurance and better value. Our solid experience in various projects of diverse complexities and scope we are well established to provide you with error free IT solutions that benefit your needs. Cost effective custom programming process features our development schedule for on-time and within budget delivery. 

Java: Development Process

Software development can be looked at from two perspectives process and product. Process is how you go about writing programs. Product is about the programming structures themselves (types, statements, classes, ...). Most programming books, as well as these notes, are concerned primarily with the product, eg, how to write a loop in a specific programming language. To be successful, you need to know all the product information, but you also have to master the process of software development, which is largely self-taught. 

There are basic program development techniques which make program development much easier, and which are used by professional programmers for maximum effectiveness.

"The longest journey starts with a single step" - Chairman Mao

The following is advocated by many top developers. It's really effective in producing programs not only faster, but with better quality.
  • Start small - Start with a small working program. It doesn't have to do what you want, but it will get you started along the path of incremental development. See Start with a working program.
  • Incremental development - Starting with a small program, make a very small change toward your goal. Compile it and test it. When it works repeat the process with another small change. Also called Iterative Programming. See Iterative/Incremental Development.

More simple techniques

  • Pair programming - Work with someone else.
  • Use good coding practices - Be scrupulous about naming and indentation. See Java Coding Standards.
  • Know your tools - Choose good tools (editor, IDE, ...) and learn them well.

Intermediate techniques

As time goes on, you will want to do some of the following.
  • Save your programs -- you may be able to use them as the nucleus for another program.
  • Create you own library. When you write a good general class or method, add it to this library.
  • Refactor (rewrite) parts of a program if you realize there is a better way. A better written program will be less likely to have bugs and will be easier to extend for the next iteration.
  • Use an IDE (Integrated Development Environment), eg, NetBeans, Eclipse, or JBuilder (see IDEs. A Java IDE requires learning, and therefore may not be a good choice for beginning programmers. However, after you are comfortable developing simple Java programs with a text editor and the JDK, the advantages of an IDE for creating user interfaces and debugging can be significant. As with all tools, learn to use it well. Check the menus for options that might be useful.

Best Practices

In any field the most effective techniques become enshrined as Best Practices. There are lots of good books (and lots that aren't good!). Here are some that I've found very good, and all of them are very readable, even enjoyable!
  • Code Complete second edition by Steve McConnell, Microsoft Press, 2004. Don't be put off by this being a Microsoft book. It's full of wonderful coding and process advice that you can use after your first programming course.
  • The Pragmatic Programmer by Andrew Hunt and David Thomas, Addison-Wesley, 2000. Filled with good product and process advice for the intermediate+ programmer.
  • Rapid Development by Steve McConnell again, Microsoft Press, 1996. This is still great, tho it could use a little updating in view of some "agile" development methodologies like Extreme Programming. This is filled with facts that everyone who works on or manages a major software development should read.
