Integrated Development Environment (IDE)
An IDE, or Integrated Development Environment, is an application that provides computer programmers a comprehensive set of tools for software development in order to boost productivity.
Most IDEs have a source code editor, a compiler, an interpreter, tools for debugging, syntax highlighting, and a method to create builds for finished software. However, not every IDE has all of the aforementioned features.
Many of the currently popular IDEs also have features specifically for use with an Object-Oriented paradigm, such as a class browser, object browser, and UML diagram generators.
As a programmer, the use of an IDE is extremely beneficial since you do not have to spread a project out between a myriad of different applications in order to complete it.
