Fortran: Classic Scientific and Engineering Computing Language
  • Relatively low functionality -- Fortran 90/95 has some object oriented features but suffers as an addon
  • Can produce very efficient (executes in a sort time) code as simplicity of language allow optimization
Pascal: Designed for teaching and elegant
  • but essentially no real software written in Pascal
C++: Dominant System building or software Engineering language
  • Very powerful language with good object oriented support
  • Not very good in applications needing high performance
C: Precursor of C++ without significant object oriented features
  • More efficient than C++ but some features (pointers) impair performance and modularity but add capability

Java: Language of Web
  • Roughly half way between C++ and Fortran with C++'s object support and Fortran's efficiency plus
  • Built in Web and Corresponding Graphics Support
  • I predict Java will replace Fortran and may replace C++
  • Learning/Teaching Java should be more rewarding/easier as Fortran..C naturally produce a bunch of numbers and words (a "print-out") while Java not only produces an image but an image on the web that can be shared with student's peers.
JavaScript: Another Language of the Web
  • A version of Java aimed at manipulating the information used in a Netscape Window
  • Limited in Scope but illustrates quickly features of Java
  • "Fully" Interpreted like Basic and so instant feedback to user

Foil 6 What is a Computing Language -I ?

A Computing Language instructs a computer what to do
A Computer manipulates information taking it from somewhere and putting it somewhere else
A language like Fortran only supports directly very basic information
  • Numbers , Words and Collections(Arrays) of them
It is more powerful to define bigger units of information
  • An HTML document
  • An Image
  • A date etc.
These are examples of "objects" and languages such as C++ Java JavaScript allow you to directly manipulate such objects

Foil 7 What is a Computing Language -II?

Full HTML Index
Objects are typically divided into classes which represent a set of objects specified with a common set of instructions but with different values for information
One builds up a set of instructions which perform a useful function
  • Convert HTML page from English to Chinese or from HTML to Microsoft Word format
  • Convert Date/Time from 12 to 24 hour format
  • Calculate trajectory of a baseball
These sets of instructions are called functions, methods or subroutines
Sets of functions/subroutines/methods(with objects) are called libraries
In object-oriented languages, methods are associated with objects and are used to manipulate and access information in an object.

Surely best to exploit Graphics and build lessons around ability to produce and manipulate Web Pages/Graphics
Low level Capabilities to produce text shapes and lines with various fonts and colors -- see CPS616 class notes
High level capabilities to modify existing code to customize a Java capability
  • see our ImageEditor (http://ocelot.cat.syr.edu/~shrideep/gcf) or
  • Java based talking heads collaboration system ( http://koum.npac.syr.edu:1972/TH/index.html) or
  • Games such as Magic Cube from (NPAC home page)
Java will produce quite easily the equivalent of PrintShop, KidPix
  • see http://beta.pixelsite.com/PS/pixelsite/pixelsite.html which is currently a CGI script but surely can be done in Java!
