Smalltalk Programming Language

Free resources updated everyday:

XXXLINKSXX

The Learning Research Group at Xerox PARC designed a language to support Alan Kay's programming paradigm. This led to the Smalltalk-72 software. After experiments were performed on Smalltalk-72, a sequence of languages ending in Smalltalk-80 were developed.

Significant Language Features

  • Object-Oriented- Smalltalk is a language in which reusable objects exchange messages.
  • Graphical Programming Environment- First look at cut/copy/paste in programming language for most people.
  • Versatile- Has many applications and uses.
  • Graphic primitives and drawing programs- Supports quickly and easily created graphics.

Areas of Application

The demand for Smalltalk programmers is growing in areas where the telecommunications industry is strong.

  • Business Information System
    1. Chosen because of Technical merit and flexibility
    2. Well suited for large projects
  • Embedded in an oscilloscope
  • Manages the telephone system of an entire country
  • Batch programs for large mainframes

Sample Program

Source Code: (Hello World)
'Hello World!'

This program was created using Smalltalk Express for Windows.

This program demonstrates how to print Hello World in Smalltalk.
