What is a flash
Macromedia Flash is a multimedia graphics program specially for use on the Web
Flash enables you to create interactive "movies" on the Web
Flash uses vector graphics, which means that the graphics can be scaled to any size without losing clarity/quality
Flash does not require programming skills and is easy to learn

The Software Engineering of Flash
In terms of interactivity: HTML  DHTML  Flash
Specify exact positioning of the various page elements statically or dynamically.
Progressive streaming by default (Flash MX as well as Flash Communication Server MX)
Supports vector graphics
Open source file format specs (not an open source technology, only the file format specs are)

Flash Concepts
Timeline
Organize and control a flash movie content over time in layers and frames
Key frames
A frame in which a change in an animation is defined
Tweening
In between  in-tween  tweening
Motion vs. Shape
ActionScript
Symbols (graphic, movie clip, button)
Path animation

Need to know
Basic knowledge of HTML
Basic knowledge of java script
Knowledge of graphics programs like Adobe Photoshop and Illustrator will make creating graphics in flash much easier

Is it an industry leader?
Macromedia Flash player numbers indicate that it is used by more then 386 million people.
It is included in all the most popular browsers, so anyone with a new version of Netscape or Internet Explorer is guaranteed to be able to view Flash movies on the Web

Flash vs. Animated Images and Java Applets
Animated images and Java applets are often used to create dynamic effects on Web pages.
The advantages of Flash are:
Flash loads much faster than animated images
Flash allows interactivity, animated images do not
Flash does not require programming skills, java applets do

Flash vs. Animated Images and Java Applets
Websites made up of music, videos, and custom, graphic intensive interfaces are all possible with Macromedia Flash.
Quick loading, especially compared to traditional methods like GIF animations

Demos
Motion Tweening
Simple animation
Draw object motion guide
Falling text
How to change the color of an object .
Shape tweening
Morphing a shape
Create your own Button
Flash Sound

Conclusion
Flash is easer to create them java applet
Some applets are programmed so they eventually take up all resources on the computer, and this results in "freezing" the browser.
There are things that you can program in java that just can't be done with Flash.

Additional Help
With Shape Tweening animation change a circle to a square using 1- 40 frames.
Use a modify transform to flip a horizontal text
