This article describes the procedure to create an Applet using the NetBeans IDE. There are mainly two ways to create an Applet in the NetBeans IDE, they are:

  • To simply write the code of the Java applet in the NetBeans Editor and "Run File" as usual.
  • Otherwise we can use the GUI Builder to make the task easer than writing long code.
