Exams3 Exams throughout the semesterWill be taken in-classThink of them as check-points to make sure we’re all on the same page.No comprehensive final!Make-ups not allowed unless you talk to the prof first.

Homework/QuizzesCommonly assignedPractice something we’ve learned

orQuestions over class preparation material (such as reading, etc)Some may be done right on Blackboard

Programming ProjectsOpportunity to use something we’ve learned and put it into practiceImplement and test complete programsWill be completed in and out of class (depending on how long it takes you)Complete solutions will be zipped and submitted to Blackboard

Interdisciplinary ProjectME, CSE and EE first-year class

Based on Lego NXT platform

Engineering in Action!

Project Kick-off: Early/mid-September!

AttendanceYou’ve got to come to class!

Your grade will reflect your attendance

Participating is required and essentialDon’t surf the net, do Sudoku puzzles, or txt at inappropriate times

Act like an adult…

Academic EthicsPillar of higher education: the work you produce should be your own.SMU Honor Code Applies to all classesIf an assignment is to be done individually (i.e. exams), it is expected that they will be completed in that mannerIf an assignment is collaborative, then you may work with your team members as much as you want (i.e. robotics project)

Inappropriate Collaboration

Penalties1st Occurrence – Zero on Assignment2nd Occurrence

F in courseHonor Council

We reserve the right to modify these penalties on a case-by-case basis.

Can you talk to your classmates?

Yes, yes, and yes!Discuss concepts, ideas, and theories.Study for examsReview reading material togetherWork on in-class assignments as appropriate

You know what’s right and what’s wrong…

The Class…

What should you know?How to use a computer

Navigate the file systemFilesFolders

How to zip and unzip files

Basic skills with Productivity Suite (i.e. Microsoft Office)How to look things up on the web (i.e. Google)Not expected to know anything about programming or Java. If you do, super! If not, don’t worry!

What’s this course about?

Fundamentally, this course is all about solving problems using a computer

Talk to/command computer using a programming language

Java in our case

You’re going to develop a set of skills which you will be able to use to solve problems using a computer

…go go gadget for loop…

What do you need for this class?

Patience… Sometimes things don’t go as expected.The textbookBinder for handoutsA computer.

Laptop would be optimal but not required. Mac, PC, Linux

What do you need for this class?

SoftwareJava 1.5 SDK or higherNetbeans Development environmentText editor

Notepad (PC)TextEdit (Mac)gEdit (Linux)Hundreds of others to choose from…

Let’s Start…How a computer scientist solves a problem…

What is Computer Science?

Study of computationWhat is possible with a computerHow to solve problems “efficiently” using a computerWhat does efficiently mean?

Tons of sub-disciplinesDatabase SystemsSecurity EngineeringNetworkingOthers?

What’s really the problem?

Figuring out the problem – vitally importantWhy?

Design a Solution - Algorithms

An algorithm isSequence of stepsSolves a problemFinishes after a finite number of steps (in a finite amount of time)

Algorithm PrimitivesMake a decision

Do something multiple times

If the lid is on the jarUnscrew and remove the lid

If turning rightengage right turn signal

Else if turning leftengage left turn signal

For each piece of breadscoop peanut butterspread on piece of bread

Implement your solutionThis is where Java (or other programming

languages) enter the sceneTranslate your solution/algo to source codeSyntax vs. Semantics

Syntax – rules of the programming language your usingSemantics – what to write - how to use the rules to your advantage

public class Solution { public static void main (String [] args) { System.out.println(“Solving the problem”); //Other stuff }}

Testing the Implementation

Verify ValidateCan’t ever test all possible scenarios (ask Microsoft!)Very complex area – you can get a PhD in Software Testing

MaintenanceAdd new featuresEnhance old featuresFix bugs discovered by usersPiece of software will spend the majority of its live in this stage…

To Do List:Read Ch 1 and 2 of Textbook

Ch 2 is most important for Wednesday
