This article mainly introduces how to use JApplet and JFrame in Swing, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

There are two classes commonly used in Swing, one is the JFrame forms class, and the other is the JApplet applet class. Where JApplet relies on the browser to execute. Many browsers can support JApplet, including IE,Firefox. However, how to use IE6 to execute, IE6 will have a script warning.

Both JApplet and JFrame are containers that contain only one component, which is an instance of JRootPane. So JApplet and JFrame are common to each other. Such as the following code:

Package com.tntxia.test.swing.jApplet; import java.awt.BorderLayout; import java.awt.Container; import java.awt.FlowLayout; import javax.swing.ImageIcon; import javax.swing.JApplet; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingConstants; public class HelloWorld extends JApplet {/ * / private static final long serialVersionUID = 52493594634447013L; public void init () {Container contentPane = getContentPane () / / if the original text is not modified, the icon cannot be displayed normally / / after modification-java.net.URL codebase=getClass (). GetResource ("loli.jpg"); JLabel label = new JLabel (new ImageIcon (codebase)); / /-the modified program has a problem, it cannot be refreshed when it is used as an applet, and once the image is refreshed, it will be gone. ContentPane.setLayout (new FlowLayout ()); contentPane.add (label);} public static void main (String [] args) {JFrame f = new JFrame (); JApplet applet = new HelloWorld (); applet.init (); f.setContentPane (applet.getContentPane ()); f.setBounds (100100400400); f.setVisible (true) }} Thank you for reading this article carefully.
