• Click on Syllabus– Weekly Assignments– Quiz and Exam Dates– Lecture Slides– Other Course Information

Course Philosophy

• Computer Science Side– Problem Solving– Logical Thought– Programming in JAVA

• “Real World” Side– Human Nature– Corporate World– Surviving during and after College

Problem Solving

• CS 115 Develops Logic Skills to Solve Problems by Writing a Program

• A Program is a Problem Solving Tool• Computers Follow Instructions Given to

Them• Computers Do Not Have “Intuition”• Computers Do Not Make Decisions “on

Their Own”

Problem Solving

• Arrange a Deck of Cards by Suit and Rank

• How Would You Do This?

• How Would You Tell a Child to Do This?

• How Would You Tell a Computer to Do This?

Why Use a Program?

• Computers Perform Tasks Many Times Faster than a Person

• Computers Are More Consistent than a Person

• Computers Can Work 24-7

Terminology• Source Code: the Original Problem-Solving, Logical

Solution Written in a Programming Language (e.g. JAVA, .java file)

• Interpretation: Converting source code into common language (.class file)

• Compiling: the Action of Turning the Source Code into a Format the Computer Can Use

• Linking: the Action of Bringing in Already Written Code (Libraries) for Use in a New Program

• Executable: the Result of Compiling and Linking a Source Program; the “.exe” file that the Computer Can Run

JAVA Required Elements

• Every JAVA Program Must Have:public class MyProgram

{ public static void main( String [ ] args)

{

}
