Refactoring capabilities are very important when working in the software industry. Anyone who has ever had to overhaul an existing code base has run into issues with changing code. One of the most common examples is moving classes between packages and having to manually edit the package statements at the top of each file. Another example is wanting to delete an element in code (such as a class member, an old utility method, and so on) and not knowing if code in your application still uses that element.

One of the most important aspects of writing code is documentation. Project documentation should not only cover system design, architecture, and logic, but also include details on how each class and method functions. The Java platform provides a very useful documentation tool called .

An important aspect of software development is controlling your source code. In single and multideveloper projects, it is essential to ensure the longevity of your code by storing the files somewhere other than on the developers’ computers. It is also important to be able to track versions of individual source files and be able to control changes.

Many problems can occur while building and developing software. One of the biggest challenges is attempting to build and compile a software application on a platform other than the one for which it was developed. Imagine three programmers working on the same application on three different platforms: Linux, Windows, and Mac.

Untested code has the potential to contain errors and bugs. Whether caused by an invalid assumption, an explicit coding mistake, or an otherwise unknown issue, bugs that appear in code cause problems. Developers lose time trying to find the mistake, organizations lose productivity, and companies lose money. For more critical systems, human lives can be lost if a software glitch occurs. This is why developers test code.

You know that it is important to write accurate and effective tests for your code. But how do you measure the effectiveness of your tests? In a perfect world, you would write a test for every class, every method, and every line of code. Depending on the complexity of your code base, this may be easy or extremely difficult.

In today’s fast-paced global economy, a determining element for success is the ability to collaborate and share information among numerous teams. Being able to communicate complex sets of data, send email, chat online, and digitally share computer screens can give software development teams a significant advantage.

Programmers often require database access tools for the purposes of development and testing. All too often, developers need to be able to add or remove a record from a specific table in order to test some code.
