7.  You must have access to a computer to successfully complete this course  Required Windows 7 SP1 or Windows 8.1 Oracle Java SE JDK 7u45 or later Eclipse IDE for Java Developers – Kepler SR 1 or later  Optional (time permitting) Google Android SDK with ADT bundle or Google Android Studio

8.  Learn fundamentals of programming using Java  Use the constructs of the Java programming language as building blocks to develop correct, coherent programs.  Analyze problems, develop object-oriented designs that solve those problems, and transform those designs to Java programs.  Understand the fundamentals of object-oriented programming using the Java programming language.  Program using the fundamental software development process, including design, coding, documentation, testing, and debugging.

9.  Programming assignments 50% Must compile and run without error. Must meet the requirements. Must include adequate documentation. Spelling and grammar count. Must follow published coding standards Must demonstrate good programming practices. Must be turned in electronically no later than midnight of the due date.   Mid-term exam 15%  Term project 20%  Final exam (cumulative) 15%

10.  Roll each class session via sign-in list  You should make every effort to attend each class meeting since class discussion will include material not found in the textbook.  Withdrawal deadline: Friday, March 21, 2014

11. History

12.  Computers were programmed using 1’s and 0’s  Each computer had it’s own “machine language”  All programs, including operating systems had to be completely rewritten for each new computer  Debugging approached impossible

13.  Engineers started seeing patterns  Effective debugging required human readable instructions  Assemblers converted human readable code to machine language  Assembly language tended to remain the same for a given model line

14.  The next level of abstraction  Programmers needed to be able to port code to many other computers  Early compilers created assembly language  Current compilers generate machine language  FORTRAN – FORmula TRANslating System  COBOL – COmmon Business-Oriented Language

15.  Fortran and Cobol are difficult languages  Kemeny and Kurtz (Dartmouth) created BASIC (Beginner's All-purpose Symbolic Instruction Code) in 1964 to teach programming concepts  Implemented as an interpreter in the 70’s  CBASIC compiled to intermediate code  Visual Basic is BASIC in name only

16.  Method to Produce provably correct code Improve clarity (readability) Reduce development time  Defined a small set of well formed constructs and rules for their use  Bohm, Jacopini, Dijkstra, Hoare, et. al.  Came to the fore in 1970’s  ALGOL, Pascal, PL/1, JOVIAL, C

17.  A method to: Increase understanding. Reduce maintenance. Support evolution.  Concepts as objects  Objects have attributes and behaviors  Extends structured programming concepts  Components based development  Smalltalk, Ada, C++, C#, Java

18.  Originally developed by Sun Microsystems  Became an Oracle product when Oracle bought Sun  Abstracted from the hardware Java Virtual Machine  Integral Object Oriented Programming Derived from C and C++  Portable code Interpreter Machine independent “bytecode”

19.  Web development (deprecated)  Server room applications  Legacy applications  Android applications

20. Java and the Virtual Machine

23. Development Environment

24.  Java Platform, Standard Edition JDK – Java for developers Server JRE – Server version of Java Runtime Environment JRE – Java Runtime Environment for end-users  Free download from Oracle http://www.oracle.com/technetwork/java/javase/do wnloads/jdk7-downloads-1880260.html http://www.oracle.com/technetwork/java/javase/do wnloads/jdk7-downloads-1880260.html Install using defaults

25.  Integrated Development Environment  Open Source Software  Eclipse IDE for Java Developers Code Recommenders Developer Tools Eclipse Git Team Provider Eclipse Java Development Tools Maven Integration for Eclipse Mylyn Task List WindowBuilder Core Eclipse XML Editors and Tools  Download and extract  Must be able to find Java (Java in the path)

26. Hello World

27.  Formally introduced by Kernighan and Richie  Introduces basics for Minimum required source code Fundamental syntax Build process from source to executable

28. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); }

29. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } Block comments begin with /* and end with */. Nothing in between executes.

30. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } Everything in Java is a class including the application which must be public.

31. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } Classes (and other blocks of code) are enclosed in “curly braces”.

32. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } Classes contain attributes and methods or behaviors. This is a method. Every application class must have a main method and it must be public.

33. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } A method within a class within another class.

34. /* * The HelloWorldApp class implements an application that * simply prints "Hello World!" to standard output. */ public class HelloWorldApp { public static void main(String[] args) { System.out.println("Hello, World"); } Let’s see how it works…
