Difference between canvas class & graphics class?

Answer

The Canvas class is a base class for writing applications
that need to handle low-level events and to issue graphics
calls for drawing to the display. Game applications will
likely make heavy use of the Canvas class. From an
application development perspective, the Canvas class is
interchangeable with standard Screen classes, so an
application may mix and match Canvas with high-level screens
as needed. For example, a List screen may be used to select
the track for a racing game, and a Canvas subclass would
implement the actual game.
The Graphics class provides the framework for all graphics
operations within the AWT. It plays two different, but
related, roles. First, it is the graphics context. The
graphics context is information that will affect drawing
operations. This includes the background and foreground
colors, the font, and the location and dimensions of the
clipping rectangle

What is the relationship between Java script, J script and
ECMA script?

Answer

JavaScript language is officially standardized as ECMAScript
(ECMA-262) by European Computer Manufacturers Association
(ECMA) International. it is internationally oriented body
embraced by Microsoft and holding the standards for C#, CLI
and Open XML.

Microsoft's own version of JavaScript is JScript and it is
mostly compatible with ECMAScript v.3. The intersection
between these three variations of the same language is at:

# JavaScript 1.5 (without DOM)
# JScript as supported by IE6 (still the most widely used
browser)
# ECMAScript ver. 3


The largest difference between JavaScript and JScript is
actually interpreter/runtime related and not language
specific. IE6 was known for some notorious performance
issues related to its non-generational garbage collector
when operating on large object trees.
