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.

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.

Final exam (cumulative) 15%
 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.

History
 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
 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
 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
 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
 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
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
 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”
 Web
development (deprecated)
 Server room applications
 Legacy applications
 Android applications
Java and the Virtual Machine

Hello World
 Formally
introduced by Kernighan and Richie
 Introduces basics for
• Minimum required source code
• Fundamental syntax
• Build process from source to executable
/*
* 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");
}
}
/*
* 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.
/*
* 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.
/*
* 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”.
/*
* 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.
/*
* 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.
/*
* 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…
