Often, we create a class that extends from JPanel as follows: public class UserDetail extends JPanel You can download the code as well as an executable jar file of this program in the attachments section.Normally we create new JPanel object as simple as follows: JPanel newPanel = new JPanel() That creates a new JPanel with double enabled by default.Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT). The default layout of applet and panel is FlowLayout. The JPanel class resides in the package javax.swing and it’s a subclass of the class. It is part of Oracle’s Java Foundation Classes (JFC) an API for providing a graphical user interface (GUI) for Java programs. FlowLayout is used to arrange components in a sequence one after the other. At the end, we will create a sample program looks like this: Table of content: The Java Swing library is built on top of the Java Abstract Widget Toolkit (AWT), an older, platform dependent GUI toolkit.You can use the Java simple GUI programming components like button, textbox, etc., from the library and do not have to create the components from scratch. JPanel is a pretty simple component which, normally, does not have a GUI (except when it is being set an opaque background or has a visual border).In this article, we summarize the common practices when working with JPanel in Swing. This Quiz game has three stages 1-> 10 Question(Easy) 2-> 20 Question(Medium) 3-> 30 Question(Hard) If you select the 10-Q(Easy) Button then the current frame is disable and two new frame is created One of the frame is Question frame and other frame is help frame.
