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
• Total 100
• 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 Higher A
• 80 89 B
• 70 79 C
• 60 59 D
• 60 or Less F

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).

Using TextPad
13
Using NotePad

• After completing the code, named Welcome1.java,
  go to Accessories/Command Prompt.
• c\gtjavac Welcome1.java // Compile
• c\gtjava 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-overv
  iew-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
