- link 1
− Unit 1 : Number Systems, Recursion and Constructors
- Day 1 HW:
- 1) Download and install Sun's JDK(the Java Developer's Kit) , BlueJ and Eclipse (You want Eclipse for Java Developers which is the top link)
- 2) Do a google search to determine the definition of 1) 'recursion' and 2) 'base case' . Be prepared to hand in the answers to these questions or to take a quiz on them.
Day 1 Class Work Overloaded constructor
- a) what is 'overloading'(Examples from Jeroo)
- b) what are the 2 ways that we can overload
- c) what is a constructor
- Here is the exact wording of one of the questions.
Below are two snippets of code from a Jeroo program. Underneath each, explain,specifically, how each one exemplifies an ‘overloaded constructor.’
| People Who Took Java Year |
For the others, do the activities listed below at the following URL |
| Recursion |
Do the following numbers 1,3,5,7,11-14 Then do recursion |
Deadline: These projects are due by Monday (except for people who must do the old assignments. They can have until next Wednesday)
Day 2 Class:
Day 2 HW: assigned problems on non-decimal handouts sheet
#4) Recursion in Java
(A+ link) . Download this file that has examples as well as well assignments
#4 HW(Friday September 11th) Read pages 71 starting with "Constants" through 79)
Week 2
#5) Recursion Groups | Download and use this tool to help you understand your recursion problem
Group 1 : Bryan , Phillip
Group 2 : Chris D, Max
Group 3 : Mike Della Rocco, Alejandro, Greg
#6) Download and run this program. Explain the output of the 3 different methods. You might want to use Jeliot.
#7) Create a class called MathWrapperin BlueJ and complete the methods asked for
#8) Download this file and run its code to help answer the questions. After you have used the BigDecimal class , visit IBM's page to answer the questions at the bottom of the page.
#9) ImaginaryNumberReducer: This class should have a constructor that takes a single parameter representing the power that the imaginary number,i, is raised to. This class should have the following methods
Week 4
- Java Arrays (Deadline: Thursday the 22nd is the last day of class time for this project and I need the code by the end of Monday.)
- Fun Arrays: ( Grading Rubric )
- Task #1) Make the constructors work correctly by initializing both arrays
- Task #2) Make the methods function as described in the source code for the project
Java Array Project 1
- Power point on Array
- String Array Project
- Two Dimensional Arrays
-
A local zoo wants to keep track of how many pounds of food each of its three monkeys eat each day during a typical week. Write a program that stores this information in a two dimensional 3 * 7 array, where each each row represents a different monkey and each column represents a different day of the week. Generate random numbers representing the amount of food (the random numbers should range from 2 to 8). Then the report should create a report that includes the following information
- Average amount of food eaten per day by the whole family of monkeys
- Least amount of food eaten by any 1 monkey during the course of the week.
- Greatest amount of food eaten by any 1 monkey during the course of the week
- Test: Friday November 6th
- single and two dimensional arrays
- there will be 1 question involving looping over a Sting as we had on the last test
- at least 1 class declaration question involving constructors, instantiate variables
- a few questions on integer and double division (like last test)
- at least 1 question involving creating a random number within a given range( ie be able to create an random number between 3 and 12 inclusive)
ArrayLists, foreach loops and Interfaces
After Thanksgiving Break- Test and start Grid World Case Study
-
Test : Monday December 7th .
-
− Grid World Links
- After you have installed Grid World, do chapter 1 from the student manual. You will have to hand this with your answers on it by Thursday.
- Pages 10- 15 as well as the associated projects and exercises should be done by the upcoming monday
- All projects including Dancing Bug are due by Thursday
12/11
- Inheritence Project
- Animal must be completed by Monday
- Grid World Student Labs
- Test: Friday January 15th. Bank Account Class is due by Friday
Test Wednesday
Interfaces in general
- String's implementation of compareTo()
Critters!!
has a relationship vs is a relationship
- Interfaces in general
- String's implementation of compareTo()
Object Oriented Programming Continued.
- Has a Relationship Projects
- The Comparable Interface
- String's implementation of the Comparable Interface. Make sure you understand the demo code before moving on to hte next assignment.
- Modify your
Student class as follows. Change the class header to public class Student implements Comparable<Student> and add the following method
- int compareTo(Student s) ;// This method should return the difference of gpas between the object and the parameter (follow the pattern for String's implementation of
compareTo).
-
Demo Code
- Extra credit: Write a method called
rankStudents() in the school class. This method should rearrange all students in its ArrayList based on the compareTo() method defined in the Student class. Method defined in the Student class.
- Grid World Part 3 and 4 (Interfaces and Critters)
Complete all parts of parts 3 and 4 except for the
- Critter Practice Test Question
- Last Critter Assignment Prior To Exam-> WizardCritter
