Course Overview

• Programming
• For the Web
• GUIs
• Object-oriented paradigm
• Problem solving
• Learn by doing
• Demonstrate through
• labs, experiments and exams
• Time intensive and unforgiving!!!

But rewarding

• "... pleasure has probably been the main goal all
  along.
• But I hesitate to admit it,
• because computer scientists want to
  maintain their
• image as hard-working individuals
• who deserve high salaries. Sooner or later
  society
• will realize that certain kinds of hard
• work are in fact admirable even though they
  are more
• fun than just about anything else."
• 
  (D.E. Knuth)

Sources of Information

• Programming Help
• Textbook
• Instructors (initial help sessions in engineering
  lab)
• Teaching assistants
• Account help
• Information Services
• Course information
• http//www.cs.tcu.edu/classinfo/
• Your classmates
• discuss syntax, design, debugging
• deliverables are your own work!

Accounts and Software

• TCU Computer Accounts
• Information Commons area of the library (1st
  floor)
• Software
• NetBeans
• Internet Explorer
• TURNIN
• Locations
• TTC 3rd floor
• Library PC Lab (first floor)
• Check with IS for additional lab locations

Succeeding in the course

• Make backups of your files
• Keep up with assignments and reading
• You cant learn by just reading
• Riding a bike
• Playing the piano
• Programming
• The machine is the master

8
History of Programming Languages

• 1940s Machine Language
• Assembly Language
• 1954 FORTRAN COBOL
• 1960 ALGOL, explosion of languages
• 1967 Simula
• 1970 BASIC Pascal
• 1972 C
• 1980 Smalltalk
• 1986 C
• 1995 Java

9
Programming Languages

• Low-level (computer language)
• Machine language 0010 0010 0000 1100
• Assembly ADD R2, 0(C)
• High-level (more like human language)
• imperative Cost Price Tax
• functional (add price tax)
• logic assert(Cost, ( Price Tax))

Java Just Another Vague Acronym?

• Originally called Oak by James Gosling
• For internet appliances (interactive TV,)
• Inspiration was a large oak tree outside his
  office
• But Oak was the name of an existing programming
  language
• Inspiration struck one day during a trip to the
  local coffee shop
• DNA and Silk were suggested for the trademark
  search. Someone said We might as well suggest
  something as silly as ... Java.

11
Why learn Java?

• Simple (relatively!)
• programmers can grasp the concepts in a short
  span of time and start producing good
  applications quickly
• Object-oriented
• programmers have access to ready-made and tested
  object libraries
• Automatic storage management
• no pointers garbage collection built in
• Secure
• security model prohibits certain types of access
• Architecture neutral
• Java Virtual Machine (JVM) can be installed on
  any platform
• Ease of migration
• looks and feels like C

Parting Thoughts

• This course is exercise for your brain
• What you practice, you become
• Dont become a lazy cheat
• DO be a person of integrity
