How to write and run the Java Applet_java under JDK and Eclipse

The source code for the Java applet is as follows:

Import java.applet.*; 
Import java.awt.*; 
 
public class Helloworldapplet extends applets {public 
  void paint (Graphics g) { 
    g.drawstring ("Hello,world", 40,60 ); 
  } 

Under Eclipse, you can run the Java applet program by clicking Run-->run directly after the program is ready.

In the JDK environment, to create an HTML file in your own Java directory, I built this file named 1.html. Compile the source program first, and then run 1.html with the Appletviewer command.

Open 1.html directly:

That's the whole process of writing and running Java applets under JDK and eclipse, and hopefully it will help you learn.
