Generate Bill is a small project which you can use to learn a small billing system. In this project, we mainly use Swing and its components. Swing in Java is a Graphical User Interface (GUI) toolkit that includes the GUI components. Swing provides a rich set of widgets and packages to make sophisticated GUI components for Java applications.
We use the following Swing component:
- JFrame: The javax.swing.JFrame class is a type of container which inherits the java.awt.Frame class. JFrame works like the main window where components like labels, buttons, textfields are added to create a GUI.
- JPanel: The JPanel is a simplest container class. It provides space in which an application can attach any other component. It inherits the JComponents class.
- JTextArea : The class JTextArea is a multi-line area to display plain text.
- JLabel: The object of JLabel class is a component for placing text in a container. It is used to display a single line of read-only text. The text can be changed by an application but a user cannot edit it directly. It inherits JComponent class.
- JCheckBox: The class JCheckBox is an implementation of a check box - an item that can be selected or deselected, and which displays its state to the user.
- JButton : JButtonis a fundamental Swing component that renders a button on-screen and responds to the user’s clicking event for performing a specific task.
