How to Make a Program in NetBeans
NetBeans is an Integrated Development Environment (IDE) designed to make the process of writing applications simpler. The IDE, available at no cost from NetBeans.org, contains a built-in editor, debugger and compiler. While it is specifically designed for Java development, plug-ins are available to support software design in C/C++ and PHP as well. At first glance, the IDE interface may appear confusing. The best way to get familiar with the NetBeans development environment is to go through the process of building a few basic programs.
