Project - Internet Privacy and Computer Security

Continue working on your projects today and tomorrow:

• Finish your notes and
• find two new sources, and
  
• prepare your outline.

Due on Monday: Notes and bibliographies of two new sources (Step1).
Due on Tuesday: Your outline (Step2).

The Internet

Today we are starting our unit about the internet. After today's class you will be able to explain how the internet works and how email works. The videos, the vocabulary sheets and the quiz on Brainpop will help you to understand the ideas. All the links can be found to the right in "Stay tuned about the internet".
In the second part of our class today we will be starting team projects about different topics on internet privacy and computer security.

Last Time Java

Today is our last day on Java.
We will have our final test and all your practices with Eclipse as posted yesterday need to be completed.

Homework
Enjoy the long week-end and celebrate Queen Victoria. See you on Tuesday.

Review and Catch Up

Today is time to review what we have learned about Java programming so far and to catch up with your Java practices.
I would like everybody to complete the following Java classes:

• HelloWorld
  (The Eclipse IDE, Slide 15)
  
• Pet class and PetMaster class
  (Java Classes and DataTypes, Slide 21)
  
• Car Class and CarOwner class
  (Java Classes - Inheritance and Method Overriding, Slide 15)
  
• Improved Car class
  (Java Control Statements for Conditional Execution, Slide 15).

Those who are done all of these can start working on the method

• caughtSpeeding of the TrafficLaws class and on the Police class (Java Bits and Pieces, Slides 11-13).

Homework
Prepare for the test using the review problems and the answer key.

The Switch Statement , Constructors and more

In Java the switch statement is alternative way to express nested if statements. We will learn how it works.
We will also have a closer look at constructors, methods to create instances of classes. We have already used the default constructors without knowing them. Today's lesson will help us to understand them better.
Watch the presentation for details.

Homework
Answer the review questions for today's lesson.
We will have a test on Java next Tuesday, May 12, 09.

Conditional Execution and Comments

In real life we often need to make decisions based on a yes/no question. Depending on the outcome we go either this way or another. In Java the control structure of the if-else statement and of the if-else-if statement help us to handle those situations in computer applications. Based on a condition the program continues either with one part or with another another.
For details watch the presentation:

In the lab we will work on and improve the Car class.

Homework
Answer the review questions about conditional execution and comments.
