4. Required Textbook Joel Adams, Alice in Action with Java, Course Technology ISBN 1-4239-0096-0 Pre-requisite 2303 Intro to MIS and Data Processing

5. Course Objectives Introduce OOP using JAVA Understand JAVA programming Understand the issues related to web- programming using JAVA

6. Evaluation 3 programming assignments Two Exams (6/25; 7/11) Final Exam (7/25, comprehensive) Point Distribution Homework 15 % First Two exams 50 % Final Exam 35 % Total100% Grades are calculated as follows: (3 homeworks/300)* 15 + (2 exams/200)*50 + (final/100)*35 100

7. Evaluation Weighted Average for Final Grade: 90 % or HigherA 80 – 89 %B 70 – 79 %C 60 – 59 %D 60 % or LessF

8. Each programming assignment will be graded based on correctness, completeness, neatness, documentation, and design. If any assignment is found to be same as the other, both assignments will be marked as ZERO, no exception. It happens twice, and the final grade “F” will be given to the student.

9. Class attendance is required. During the class, any student who leaves without notice will have penalty (5 points each occasion).

10. Software JDK 2 SDK, SE version 1.6 http://java.sun.com TextPad (freeware, editing software) http://www.textpad.com NotePad Eclipse http://www.eclipse.org/downloads/

11. Lecture Note

12. Using TextPad

13. Using NotePad After completing the code, named Welcome1.java, go to Accessories/Command Prompt. c:\>javac Welcome1.java// Compile c:\>java Welcome1 // Execute

14. History of the Language Java Developed by Sun Microsystems in 1991 as part of a project to develop software for consumer electronic departments (TVs, VCRs, toasters,etc.). Its goal was to be small, fast, efficient, and easily portable to a wide range of hardware devices.

15. A Definition of Java Java is a “simple, object-oriented, interpreted, robust, secure, architecture-neutral, portable, high-performance, multithreaded, and dynamic language.” From “The Java Language: A White Paper” http://java.sun.com/docs/overviews/java/java-overview-1.html

16. Java is simple Small: easier to write, easier to compile, easier to debug A subset of C++ Omits confusing features of C++ no pointers or pointer arithmetic string and arrays are real objects memory management is automatic no multiple inheritance no operator overloading

17. Java is Object-Oriented Focus design on objects and interface inheritance (new classes inherit characteristics of existing classes) encapsulation (fields/methods can be hidden) polymorphism (same code has different effects at run time) message passing (passing information to methods)

18. Java is Interpreted Compiles to byte code, not machine code Interpreted by the browser Benefits: rapid prototyping easy experimentation Java Source Code Java compiler Java Bytecode Code Java Interpreter CPU JVM

19. Traditional Compiled Programs Your code Compiler (Pentium ) Compiler (PowerPC) Compiler (SPARC) Binary File - Pentium Binary File - PowerPC Binary File - SPARC
