What is .FORM file extension?
Form created by NetBeans Swing GUI Builder, a tool for building Swing GUIs included in NetBeans IDE; contains placement of GUI components for Java Swing; each file is devoted to a Java class; when a component is added to the FORM file, a corresponding field is added in the connected class.
NOTE: When using the NetBeans Swing GUI Builder, the FORM files regenerate the portion of the .JAVA source files designed by the Builder, such as the appearance of buttons, overwriting any manual changes to the design of the files.
