difference b/w awt and swing

            difference b/w awt and swing

AWTSwing
AWT stands for Abstract windows toolkit.Swing is also called as JFC’s (Java Foundation classes).
AWT components are called Heavyweight component.Swings are called light weight component because swing components sits on the top of AWT components and do the work.
AWT components require java.awt package.Swing components require javax.swing package.
AWT components are platform dependent.Swing components are made in purely java and they are platform independent.
This feature is not supported in AWT.We can have different look and feel in Swing.
These feature is not available in AWT.Swing has many advanced features like JTabel, Jtabbed pane which is not available in AWT. Also. Swing components are called "lightweight" because they do not require a native OS object to implement their functionality. JDialog and JFrame are heavyweight, because they do have a peer. So components like JButton, JTextArea, etc., are lightweight because they do not have an OS peer.
With AWT, you have 21 "peers" (one for each control and one for the dialog itself). A "peer" is a widget provided by the operating system, such as a button object or an entry field object.With Swing, you would have only one peer, the operating system's window object. All of the buttons, entry fields, etc. are drawn by the Swing package on the drawing surface provided by the window object. This is the reason that Swing has more code. It has to draw the button or other control and implement its behavior instead of relying on the host operating system to perform those functions.
AWT is a thin layer of code on top of the OS.Swing is much larger. Swing also has very much richer functionality.
Using AWT, you have to implement a lot of things yourself.Swing has them built in

MVC Example 1

                        Swing MVC Example in java Java Swing first programs In this chapter, we will program our first programs in Swing toolkit. The examples are going  to be very simple. We will cover some basic functionality. Our first example In our first example, we will show a basic window. import javax.swing.JFrame; public class Simple extends JFrame { public Simple() { setSize(300, 200); setTitle("Simple"); setDefaultCloseOperation(EXIT_ON_CLOSE); } public static void main(String[] args) { Simple simple = new Simple(); simple.setVisible(true); } } While this code is very small, the application window can do quite a lot. It can be resized, maximized, minimized. All the complexity that comes with it has been hidden from the application programmer. import javax.swing.JFrame; Here we import the JFrame widget. It is a toplevel container, which is used for plac...
