Swing Framework includes a number of classes that provide GUI components that are more strong and versatile than AWT. Then you need to add it to the frame by using the method - add(Component's Object) You can add the following method also for resizing the frame - setResizable(true) JButton allows an icon, string or both associated with a button. JTextField : JTextFields allow editing of a single line of text. Creating a JFrame in java There are 2 ways we can create a JFrame Window. By instantiating JFrame class. By extending JFrame class. Creating JFrame window by Instantiating JFrame class import javax.swing.* //importing swing package import java.awt.* //importing awt package public class First Points to note: Import the javax.swing and java.awt package to use the classes and methods of Swing. While creating a frame (either by instantiating or extending Frame class), the following two attributes are a must for visibility of the frame: setSize(int width, int height) setVisible(true) When you create objects of other components like Buttons, TextFields, etc. JLabel : JLabel has descended from JComponent, and is used to create text labels. JButton : JButton class provides the functioning of push button. Like Window it uses BorderLayout by default. JWindow : This is Swing's version of Window and has descended directly from Window class. The component which is added to the Frame, is referred to as its Content. JPanel is descended directly from JComponent. JFrame : JFrame is Swing's version of Frame and is descended directly from Frame class. Java Swing belongs to the Java Classes Foundation (JFC). Features of JFC Swing GUI components. Look and Feel support. Java 2D. AWT and Swing HierarchyIntroduction to Swing Classes: JPanel : JPanel is Swing's version of AWT class Panel and uses the same default layout, FlowLayout. It is used to build Java's graphical user interface. In javax.swing package and its sub-packages, swing classes are described. Main Features of Swing Toolkit Platform Independent Customizable Extensible Configurable Lightweight Rich Controls Pluggable Look and FeelSwing and JFC JFC is an abbreviation for Java Foundation classes that includes a set of characteristics to build Graphical User Interfaces (GUI) and add wealthy graphical characteristics and interactivity to Java apps. Swing is an official Java GUI tool kit published by Sun Microsystems that offers the look and feel of contemporary Java GUI. This package defines Listeners & Events which Swing components use to communicate asynchronously.Java Tutorial By KnowledgeHut Swing Framework includes a number of classes that provide GUI components that are more strong and versatile than AWT. This package contains the core Swing components, including the model Interfaces and Helper classes. Some of the Swing packages are as follows: Swing Package The entire package using the below statement: We need to import the Swing components in the Java code. We can also customize the application to use the platform’s custom Look-and-Feel. This allows Swing GUI components to have a uniform Look-and-Feel for the Java application across all platforms. Swing enables pluggable Look & Feel to allow Java applications to have look and feel independent from the underlying platform. Swing provides various text components and dialog boxes. Swing offers various button types such as push-button, check box, radio button, etc Swing provides various layout managers to arrange GUI components inside a container. The AWT GUI components can be used from java.awt package. Java Swing is developed based on AWT(Abstract Window Toolkit ) APIs.Swing provides more sophisticated GUI components than AWT. JFC contains features for building Graphical User Interfaces. Java Swing is a part of Java Foundation Classes (JFC). Java Swing API is a set of APIs that provides GUI(Graphical User Interface ) for Java programs. In this tutorial, we will learn about Java Swing API.
