Take a look at the Java Curriculum

Discuss the Summer Assignment

Open BetterTurtle, look at:
- Reserved words
- Method signatures
- Instance/Class variables

Read 1.1-1.4 and 1.7, 1.8 in text
Define the vocabulary words using this sheet

Go over the Vocabulary homework
Chapter 1 Question Sheet (Type your answers, then print it out)
Short quiz next class on Chapter 1.

Need help on the Summer Lab? Stay after today or Thursday. (Must get to me BY Friday)

• Look at the API of Turtle and Turtlet
• Discuss static methods vs. inheritance
• On paper, WRITE an application program that constructs a Turtle and slowly draws 5 red concentric circles with increasing radii (20, 40, ... 100) using a for/loop. Make the radii increment a variable set outside of the loop! Then, using the same Turtle, draw 5 blue concentric circles with decreasing radii (110, 90, ... 30) using a while loop. Again, make the decrement a variable.

• Objects, class, instance, reserved word, instance variable, class variable, signature, inheritance, method, static method, main, polymorphism

• Quiz on Chapter 1
  
• Discuss the vocabulary homework
  
• Continue with while loops
• Discuss Do-While loops
• Lab Assignment #1
  

Read all of Chapter 2 in the text

Quiz Next class on Chapter 2

• Chapter 2 Quiz
  
• MAKE SURE I HAVE YOUR Summer Assignment
  
• Continue Lab Assignment #1 (To be completed next class.)
  

• Complete Lab Assignment #1
• Show me when you are done - I will go over with you at your computer.
• TEST NEXT CLASS on writing classes.

• Test #1 - Objects and Classes
• Add to vocabulary
• Primitive data type, class, parameter, accessor, modifier, declaration, assignment, reference
• Java Review - A Powerpoint
  
• Primitives: int, double, boolean
• Accessors and modifiers
• Subclasses

• We will go over the tests next class (Mueller needs to take the exam.)
• Continue with the Summer Assignments. (Need Beck's.)
• Summer Assignment
  
  • Labs 1 and 2 dealt with statistics
  • Lab 3 dealt with dates
  • Lab 4 dealt with strings/palindromes
• Take a look at Summer Labs 1 & 2; Add to your Utility class the following two methods:
  • countMins(int[] list) // returns the number of times the smallest element in the list occurs
  • allDifferent(int[] list) // returns true if there are no duplicates in the list, false otherwise
  • ArrayList getModes() // upgrade of the current one such that this will return ALL modes
  • Add a println to your main method in the App that will print the result of these method calls.

Homework: In the AP-API, review the following classes

-ArrayList, Double, Integer, Math, Object, Random, String, System

-For each class, make a list of EACH METHOD that is new to you

-Read through all the exceptions and note any questions

• Go over the tests - Stat Sheet
• Go over the API HW
• Discuss utility (static) classes vs. object classes vs. application classes
• Finish Summer Lab Additional Methods
• Begin homework

• Discuss utility (static) classes vs. object classes vs. application classes
• Discuss class design
  • Kinds of instance variables
  • Kinds of methods
    
• Write Lab #2: The Car Class

• Discuss Exceptions
• Put Exceptions into our Car Class
• Work on the Summer Lab Upgrade (countMins, allDifferent, getModes)
• Show me your car and summer lab upgrades if complete

Finish Car and Summer Lab Upgrades

• Finish Summer Lab Upgrade
• In BlueJ, create a new project called "Vehicle" in your labs folder.
• Briefly look at interfaces and abstract classes
  

• Design Discussion for the classes needed to keep inventory for a car dealership

• Reports: all vehicles, vehicles within a particular category, number of vehicles, total cost, etc.
• Ability to search for vehicles that satisify particular criteria (ie. efficiency > 20mpg, 4wd, price < $22g)

• Place your vehicleData.txt file in your Vehicle Project folder
• Discuss the structure of our new project and abstract vs. super classes
• Discuss what informations is specific to the type of vehicle and what is general. (Ie. only a car should have a boolean convertible field.)
  
• Decide on a small subset of data fields to include in our Vehicle class. Put in modifier (mutator) and query (accessor) methods for each field.
• Brainstorm what reports/functionality our inventory program should have

• We will use a Utility class (with static methods). Think and write down the types of actions we would like our project to be capable of accomplishing. (Ie. what type of reports to generate.)
• Write down IN SIMPLE ENGLISH what would be involved (ie. the process) to find the most expensive vehicle.

• Create the Car, Truck, and SUV classes.
• Write an application program (VehicleTest) to instantiate all three types of vehicles as three elements of a Vehicle[]. Be sure to put a toString() in Vehicle and print the vehicles in your App.
• Create a Utility class and write a static method to print the data in the array.
  public static void printVehicleList(Vehicle[] theVehicles)
• Look at the Scanner class and write a static method to read data from your file.
  public static Vehicles[] read(String filename, int size)

* This reading covers the Selection and Mergesorts.

- DO NOW (FOR LOOP Fun)
- Make this application program work for Vehicle

You will be adding a read method.

Finish Ch. 19 (19.6 to the end)
Topic is searching

(Hand in HW on a sheet of paper with your name/date/Class #20 HW)

Read Chapter 4 in the text (including all parts!)
* Complete Exercises R4.1 to R4.4 and R4.6 to R4.9

• Chapter 18 in the text covers Recursion
• Read 18.1 and 18.2 (pages 664 through 671)
• Read 18.4 (678 to 684)
• LOOK AT Exercise P18.13 - TOWERS OF HANOI

• Think about the problem
• Then Google Towers of Hanoi and look at some solutions and applets that show what is happening.
