You can use images as buttons, or background for your software designed in Java, so how would you get started with the Java GUI programming? In this Java tutorials for beginners with examples I will show your how to created and run your first GUI program with Java JDK. Contents.Swing GUI widget toolkitJava provides you a complete set of GUI toolkit named “SWING” it is an Application Programming Interface (API) for creating a graphical interface in Java programming.
Swing toolkit was developed to replace the Abstract Window Toolkit (AWT) which was the older version of graphics toolkit.Swing came with a more sophisticated set of GUI components that could be used to emulate the look and feel of multiple operating systems, swing package made it possible for the softwares to have completely different visual than underlying platform. Basic Components of Swing1. Import javax. JFrameJFrame is the container component, it holds all the other components of the swing architecture. It initially creates an invisible frame.3. JLabelA display area for a short text string or an image, or both. A label does not react to input events.
As a result, it cannot get the keyboard focus. A label can, however, display a keyboard alternative as a convenience for a nearby component that has a keyboard alternative but can’t display it.A JLabel object can display either text, an image, or both.4. JButtonA button is a highly required component of any software, it can be either Submit button, clear button, menu button etc.JButton is an implementing of a “push” button. Buttons can be configured, and to some degree controlled, by Actions. Using an Action with a button has many benefits beyond directly configuring a button.

INFORMATIONMESSAGE );JOptionPane. ShowMessageDialog ( null, 'Warning Message', 'Title', JOptionPane. WARNINGMESSAGE );JOptionPane.
ShowMessageDialog ( null, 'Error Message', 'Title', JOptionPane. ERRORMESSAGE );It is very easy to build a GUI program in Java, it is not much different than command line programming, so if you have the basic knowledge of the command line, then now is the time to switch to GUI programming because that is the future. If you are new to Java programming I would highly recommend you to read.If you found this Java tutorials for beginners with examples helpful to you, don’t forget to share it with your friends and classmates.
