Introduction

• Course description
• COP 3252 Advanced Java Programming (listed as
  Internet Programming w/ Java)
• Prerequisites COP3330 and COP3331
• Topics include Java basics, a review of
  structured and object-oriented programming
  concepts, classes, constructors, interfaces,
  exceptions, I/O, graphics concepts, compilation,
  applets, APIs, JDBC, Sockets

5
Attendance

• Attendance is required for all lecture and
  recitation classes
• Attendance will not be taken on a daily basis
• In-class quizzes will be used as attendance
  (participation)

6
Class Structure

• Beginning (first few weeks) Basic concepts of
  programming in JAVA.
• How to compile and run programs.
• Basic language structure and elements
• Variables, loops, control structures, etc.
• Middle Intermediate concepts and programs.
• Input and output streams, exception handling,
  etc.
• Networking, concurrency (threading), database
  connections, etc.
• End Graphical programming concepts.
• Creating graphical programs to perform useful
  functions.

7
Assignments

• Assignments will be given on a weekly or
  bi-weekly basis depending on the difficulty level
  of the assignment.
• Assignments are due by the date posted on the
  assignment webpage.
• 20 Penalty on assignments if they are up to one
  day late (assignments that are more than 24 hours
  late will not be accepted).

8
Extra Credit

• Some assignments have the opportunity for extra
  credit
• Extra credit can be anywhere from 5 to 50 points.
• Programs must be submitted by the due date in
  order to earn extra credit.

9
Class Book

• Java How to Program, Seventh Edition by Harvey
  M. Deitel and Paul J. Deitel
• Some assignments may come directly from the book
• The book will be used as a reference for
  programming concepts. (All test questions come
  from the lecture notes.)
• Reading may be assigned from the chapters.

10
Programming Assignments

• Assignments should be created, compiled and
  tested by
• Using the Computer Science department servers
  (linprog.cs.fsu.edu and program.cs.fsu.edu) via
  SSH
• Using an IDE such as JCreator (included with the
  course textbook) along with the JAVA SDK from
  www.sun.com

11
Accessing the CS servers

• You must obtain a Computer Science account
• This account will be used to access the CS
  servers through Secure Shell.
• This account must be obtained by the start of the
  2nd week of class
• Successfully obtaining this account will be part
  of your assignment 1 grade.
• Instructions for obtaining an account
  http//system.cs.fsu.edu/newusers/newaccount.php

12
SSH

• The SSH (secure shell) client is used to access
  the CS servers
• This client is installed in all computer labs on
  campus
• It can be downloaded from http//sl.us.fsu.edu
  when on an FSU connection.
• You can access the CS servers from anywhere in
  the world using SSH

13
Using SSH to program

• The next class will focus on using the SSH client
  as well as the UNIX text editors and the JAVA
  complier
• Note The use of the JCreator IDE will not be
  covered in this course until we reach the
  graphical programming section of the notes.

14
Assignment Assistance

• If you need help on an assignment, you have
  multiple options
• Visit the instructor in his office. An
  appointment can be made anytime between 8am and
  5pm.
• Send your question to thornton_at_psy.fsu.edu . Be
  sure to attach any program source code with your
  e-mail.
• E-mail questions will generally be replied to
  within an hour if received during normal business
  hours (8am 5pm). After hours questions may not
  be replied to until the next day.
• Make sure to include a copy of your source code
  along with your question.

15
Turning in Assignments

• Assignment due dates are posted on the assignment
  description page and on the course calendar.
• Assignments are to be turned in using the Digital
  Dropbox on the BlackBoard system.
• DO NOT E-MAIL ASSIGNMENTS (unless instructed to
  do so)

16
Assignment Grading

• The instructor will grade the programming
  assignments
• The grading guidelines will be posted with the
  assignment descriptions
• Assignment grades are usually posted within 7
  days of the due date.
• If you have questions about your assignment
  grade, e-mail the instructor.

17
Exams

• The exam dates are not known at this time.
• You will be given at least a 1-2 week notice for
  exam dates.
• The class before the exam will be a review class.
• Exams questions come directly from the lecture
  notes and material discussed in class.
• Questions will be a mix of multiple choice, short
  answer, and fill in the blank.
• You may be required to produce source code on the
  exams.
• Exam answers will be given in class after the
  exam is administered.

18
Final Exam

• The final exam is cumulative.
• Many questions from the previous two exams will
  be repeated.
• You must have an average of 70 or higher on
  exams in order to pass the class with a C- or
  higher.

19
Introduction to JAVA
20
JAVA Introduction

• Object-oriented programming language
• Uses abstraction to create models based on the
  real word
• Inheritance, modularity, polymorphism, and
  encapsulation.
• Borrows syntax from both C and C
• NOT related to JavaScript
• The two share syntax, but are not complimentary
  languages.

21
JAVA History

• Started as Oak (James Gosling 91)
• Intended to run on all systems
• WORA Write Once, Run Anywhere
• Quickly incorporated into many popular web
  browsers
• Controlled by and maintained by Sun Microsystems
  (http//www.sun.com)

22
Why JAVA?

• Platform independence
• Runs the same on all hardware
• Automated Memory Management
• The JAVA runtime performs all memory allocation
  and deallocation.
• Its easy!
• Many objects and code pieces are already written
  for you
• Graphical programs are very easy to create and
  manipulate.

23
JAVA Code Files

• Source Code .java files
• Object Code (compiled code) .class files
• JAVA Archive .jar files
• .java file is compiled into a .class file
• JAVA SDK (Software Development Kit) is require
  for compilation
• .class file is the executable
• JRE (Java Runtime Environment) is required for
  execution

Sample Program

• // Fig 2.1 in book
• public class Welcome1
• public static void main( String args )
• System.out.println(Welcome to Java)
• //end method main
• //end of class Welcome1
