Java
• Developed by Sun
• Object Oriented Language
Compiling the source program into a
special type of object code, known as
Byte Code
Byte Code can run on any computer
with a Java Virtual Machine (JVM)

A Simple Java Program
//This program prints Welcome to Java!
public class Welcome {
public static void main(String[] args) {
System.out.println("Welcome to Java!");
}
}

Create Source Code
Source code (developed by the programmer)
public class Welcome {
public static void main(String[] args) {
System.out.println("Welcome
to Java!");
}
Saved on the disk

to read and interpret, not for you to understand)

How to execute
Java Applet
Java applets are small Java programs
that get downloaded to your
computer and then run from a web
browser when a web page that uses
Java is loaded.
• *.class
Java Applet
Example (WA.java)
import javax.swing.JApplet;
import java.awt.Graphics;
public class WA extends JApplet {
public void paint(Graphics g) {
g.drawString("Welcome to Java!",25,25);
}
}
Java Applet
Embed Java Applet in HTML (WA.html)
<html>
<applet code=“WA.class”>
</applet>

Java Applet
Execution
JAR
JAR (Java Archive)
• A platform-independent Data Format
• Aggregating many files into one
• Multiple Java applets and their requisite
components (class files, images, and
sounds) can be bundled in a JAR file
• Subsequently downloaded to a Browser
in a single HTTP transaction, improving
the download speed
ActiveX
A set of technologies from Microsoft
Providing tools for linking desktop
applications to the World Wide Web
Using a variety of programming tools-including Java, Visual Basic, and C++-developers can create interactive Web
content
Allowinh users to view Word and Excel
documents directly in a browser
Anfy
Tool for Building Java Applet
FrontPage and Anfy
Anfy can output Java Applet
We can paste the Applet to a HTML file by
FrontPage

使用FrontPage插入Java Applet
在FrontPage的Java Applet屬於進階控制
項，只需擁有Java Applets或從Internet
下載現成的Java Applet，就可以使用
FrontPage在網頁插入Java Applet控制項。

Step 1

Step 2
• The applet "Width" and "Height" are
automatically entered when you specify
the screen image and a "Resolution"
value.
Give A Figure
Anfy Lab
Step 2
• Next three parameters below "Intensity"
decide how changeable the wind is.
• With "Var. speed", you can set how fluently
the wind changes its direction and speed. A
higher value gives a faster change. The wind's
behaviour itself is dynamically calculated and it
does not show static behaviour.
• You can limit the maximum and minimum wind
speed at "Var. max" and "Var. min".
Anfy Lab
Step 2
• "Wave speed" literally controls the speed of
the wave. Lower values produce very slow and
calm wavings; whereas higher values result in
very busy motion.
• "Perspective" decides how the waves have to
be stretched for perspective simulation. In
other words, with this parameter, you can
control visual distance between waves. Lower
values mean narrow space in between waves
and it looks very busy.
• "Farwaving" parameter (values from 1 to
10000) allows you to determine how strong
the far waves (top of lake) must be.
Anfy Lab
Step 2
• This "Half reflect" option allows you to
shrink the reflection into the half size

Step 5
• If you would like the applet to be linked
to a certain url, select "Enable link"
and enter the link url below space.

Step 6
• Click "Copy all files
to..." button and
specify a destination
file name, say,
home.html to which
the HTML code will
be output and the
necessary .class
files will be copied
to the same folder.
