Programs Of Java Swing

The main difference between AWT and Swing in Java is that the AWT is ’s original platform-dependent windowing, graphics, and user interface widget toolkit while the Swing is a GUI widget toolkit for Java that is an extension of AWT.Java is a high-level, general-purpose programming language that supports, multithreading, platform-independency, and many other features. The programmer can write a variety of applications including desktop, web, mobile, image processing, etc. Using Java language. It provides toolkits to build rich Graphical User Interfaces (GUI). AWT and Swing are two of them. Key Areas Covered1.– Definition, Functionality2.– Definition, Functionality3.– Definition, Functionality4.– Comparison of Key Differences Key TermsAWT, GUI, Java, SwingWhat is a GUIGUI stands for Graphical User Interface. It is an interface that allows the users to operate an application and perform the required tasks.

Also, a GUI consists of various components. Window, buttons, radio buttons, check boxes, labels, drop down lists, text fields, combo boxes are some GUI components.

These components can trigger events. For example, a new page opens after clicking a button, or the user can enter the registration details and press the submit button. Most applications have a GUI to allow the user to communicate with the application. What is AWTAWT stands for Abstract Window Toolkit. It is an API to develop GUI or Windows-based applications in Java.

It requires a native OS object to implement the functionalities. Also, AWT components are heavyweight and require more memory space. Moreover, they take some time to execute. Furthermore, the programmer has to import the javax.awt package to develop an AWT based GUI. Button, scrollbars, text fields, lists, dialogs, and panels are some AWT components. After creating objects, they are placed in a container.

Also, it provides the required space for the components to load. Usually, AWT application in one OS might look different in another OS. What is SwingSwing is a GUI widget toolkit for Java.

It is built on top of the AWT API. Also, it is a part of Oracle’s Java Foundation Classes (JFC). Furthermore, Swing provides basic components such as labels, textboxes, buttons, etc. As well as advanced components such as tabbed panes, table, and, trees.

Therefore, Swing provides more sophisticated components than AWT. Here, the programmer has to import javax.swing package to write a Swing application. This package provides a number of classes such as JButton, JTable, JList, JTextArea, and, JCheckBox. Figure 1: Simple Java Swing applicationSwing is platform-independent and its components are lightweight. Furthermore, the components require minimum memory space. Therefore, Swing applications execute much faster.

One common design pattern in development is Model, View, Controller pattern. Swing follows this pattern. It helps to maintain the code easily. Difference Between AWT and Swing DefinitionAWT is a collection of GUI components (widgets) and other related services required for GUI programming in Java. Swing is a part of Java Foundation Classes (JFC) that is used to create Java-based Front end GUI applications. Hence, this explains the main difference between AWT and Swing in Java.

TypeAWT components are heavyweight while Swing components are lightweight. Platform DependencyAnother major difference between AWT and Swing in Java is that AWT is platform dependent while Swing is platform independent.

DisplayMoreover, AWT does not support a pluggable look and feel. Swing supports a pluggable look and feel. This is also an important difference between AWT and Swing in Java.

ComponentsAlso, Swing has more advanced components than AWT. SpeedFurthermore, execution of AWT is slower. However, Swing executes faster. MVCAWT does not support MVC pattern while Swing supports MVC pattern. This is another difference between AWT and Swing. Memory SpaceMoreover, AWT components require more memory space while Swing components do not require much memory space.

PackageThe programmer has to import the javax.awt package to develop an AWT-based GUI. However, the programmer has to import javax.swing package to write a Swing application.

ConclusionIn brief, AWT and Swing are two toolkits to build rich Graphical User Interfaces (GUI). The main difference between AWT and Swing in Java is that AWT is Java’s original platform dependent windowing, graphics and user interface widget toolkit while Swing is a GUI widget toolkit for Java that is an extension of AWT. “AWT Overview.” Www.tutorialspoint.com,.2. “SWING Overview.” Www.tutorialspoint.com.3. “Swing (Java).” Wikipedia, Wikimedia Foundation, 9 June 2018,.4. “Abstract Window Toolkit.” Wikipedia, Wikimedia Foundation, 26 Aug.
