In this module you have been using the BlueJ IDE, which is ideal when you are learning to program in Java and work with classes and objects. However, you don’t need to use BlueJ to write programs, and most advanced and professional developers prefer to use one of a range of sophisticated IDEs that are available for Java and provide a wide range of features to make development as productive as possible and provide help with, for example, creating graphical user interfaces. This week you will learn to use NetBeans to create a simple graphical interface for a Java program.
