Title: TCU CoSc 10403 Introduction to Programming with Java


1
TCU CoSc 10403 Introduction to Programming (with
Java)
  • Course Introduction

2
Agenda
  • Roll
  • Course Overview
  • Finding information (www.cs.tcu.edu/classinfo)
  • Getting help (instructor TAs)
  • Succeeding in the course
  • (study hard_work programming) success)
  • Computer Accounts - everyone MUST have a TCU
    computer account (not Gmail, not HotMail,
    etc.)!!!
  • Turn cellphones OFF no texting, emails, or
    phonecalls!
  • Programming and Java Background - no assumption
    is made about previous programming experience!

3
Course Overview
  • Programming
  • For the Web
  • GUIs (using Swing classes)
  • Object-oriented paradigm
  • Problem solving
  • Learn by doing
  • Demonstrate through
  • labs, experiments and exams
  • Time intensive and unforgiving!!!

4
Sources of Information Help
  • Programming Help
  • Textbook
  • Instructor (initial help sessions in TTC 335 -
    next Tuesday)
  • Lab assistants
  • Account help
  • Information Services
  • Course information
  • http//www.cs.tcu.edu/10403/
  • Your classmates
  • discuss syntax, design, debugging
  • deliverables are your own work!
  • Sun Microsystems web (java.sun.com)
  • Eclipse IDE
  • www.eclipse.org/
  • and
  • http//www.eclipse.org/downloads/ (select your
    platform)

5
For Next Class Period without fail!!!!
  • Go to the class website
  • http//www.cs.tcu.edu/10403
  • (2) Click on the Lab Eclipse Introduction.
  • (3) Print off a copy of the tutorial.
  • (4) Bring it with you to class next period we
    will meet in TTC 353 DONT Forget!!

6
Accounts and Software
  • TCU Computer Accounts
  • Information Commons area of the library (1st
    floor)
  • Software
  • Eclipse IDE - Java component
  • Internet Explorer
  • TURNIN
  • Locations
  • TTC Labs (353 357)
  • Library PC Lab (first floor)

7
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
About Java
  • Designed and implemented by Sun Microsystems,
    Inc.
  • A very young language - 1st brought to the
    attention of the public in 1995.
  • Designed as a device independent language
    (originally named Oak) for use in consumer
    electronic devices (microwaves ovens, smart TVs,
    thermostats, etc.)
  • In 1992/93 the WWW arrived - since the language
    was device independent, Sun soon realized that
    Java would be suitable for writing programs to
    run on different computers connected to the
    Internet.
  • It was the 1st language to provide features to
    allow programs to be downloadable as part of a
    web page (and run on a users computer).

9
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.

10
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

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

12
More about Java
  • The language is small in size and simple to
    learn.
  • The power of the language comes from the
    extensive library of software components that
    have already been developed and are available for
    use.
  • Java programs consist of pieces called
    classes.
  • There are two things to master in order to learn
    to program in Java
  • Learning the Java language itself so that you can
    program your own classes, and
  • Learning what is already available in the
    extensive Java class libraries and how to use
    them.
  • The language can be used to develop both stand
    alone applications and applets.

13
Java application vs. applet
  • Application
  • Stand alone (e.g. MS Word, Firefox, )
  • Applet
  • Embedded in a web page

This course teaches how to create applets, but
not too difficult to change between
application/applet
