Week 1 Individual: Singleton Pattern Program
Write a Java program (non-GUI preferred) to
demonstrate the Singleton pattern.The key parts of the singleton pattern
are:

  • A private static variable to store the single
    instance called the singleton

  • A public static method for callers to get a
    reference to the instance

  • A private constructor so no callers can instantiate
    the object directly

Using these key parts,
write a Java program that will allow a user of the program to assign only one
runner to each of the 8 lanes of running track in a field.Include a brief documentation (in the code or in a separate document) to explain
the input (if any), processing and output of the program.Submit your assignment using the Assignment Files tab above.       Week
2 Individual: ArrayList ProgramWrite a Java program (non-GUI preferred) to
demonstrate the use of an ArrayList.The program should allow a user to do the
following:

  • Add, edit, delete different types of animals

  • Select an animal, and the corresponding
    characteristics will be displayed (such as color, vertebrate or
    invertebrate, can swim, etc.)

  • The program must use ArrayList(s) to work with these
    animal objects.

Include a brief documentation (in the code or in a separate document) to explain
the input (if any), processing and output of the program.Submit your assignment using the Assignment Files tab above.      Week
2 Learning Team: Program Improvement ISelect one program submitted by a team member in
Week One.Suggest at least 3 ways to improve the selected program.  One of these
improvements must be related to applying assertion, exceptions, data formatting
or localization.Write code and test the
improved program.  Deliverables should include:

  • The source code file(s) of the improved program.

  • A 2- to 3-page paper on the approach the team has
    taken to improve the program.

  • Why some of the changes are relevant to this week's
    objectives.

  • Any challenges the team encountered and suggest any
    future improvements.

Submit your assignment using the Assignment Files tab above.         Week
3 Individual: Iterator ProgramWrite a Java program (non-GUI preferred) to
demonstrate the use of Iterator.The program should allow a user to do the
following:

  • Allow the reading of a collection of animal objects
    from an external file.

  • Output on screen the content of a collection of
    animal objects.

  • Use Iterator to achieve these goals.

Include a brief documentation (in the code or in a separate document) to explain
the input (if any), processing and output of the program.Submit your assignment using the Assignment Files tab above.       Week
3 Learning Team: Program Improvement IISelect one program submitted by a team member in
Week Two.Suggest at least 3 ways to improve the selected program. One of these improvements
must be related to the use of generic class, a collection or Java File I/O.Write code and test the
improved program.  Deliverables should include:

  • The source code file(s) of the improved program.

  • A 2- to 3-page paper on the approach the team has
    taken to improve the program.

  • Why some of the changes are relevant to this week's
    objectives.

  • Any challenges the team encountered and suggest any
    future improvements.

Submit your assignment using the Assignment Files tab above.      Week
4 Individual: JDBC ProgramWrite a Java program (non-GUI preferred) to demonstrate
the use of JDBC.The program should allow a user to do the
following:

  • Write a list of animal and its characteristics to a
    database using JDBC

  • Display the characteristics of an animal when that
    animal is selected.

Include a brief documentation (in the code or in a separate document) to explain
the input (if any), processing and output of the program.Submit your assignment using the Assignment Files tab above. Note from Instructor:To assist, I have included a demo file
"JavaDB week 4 Demo code" of a database and installation
instructions.

PLEASE USE THIS DEMO DATABASE.  I have had
students want to use other database engines and it makes it very difficult when
that happens.  This is not a class in different databases, but just how to
connect Java to a database, and thus we are going to use the simplest one
possible, mySQL.     Week
4 Learning Team: Program Improvement IIISelect one program submitted by a team member in
Week Three.Suggest at least 3 ways to improve the selected program. One of these improvements
should be related to the use of JDBC.Write code and test the
improved program.  Deliverables should include:

  • The source code file(s) of the improved program.

  • A 2- to 3-page paper on the approach the team has
    taken to improve the program.

  • Why some of the changes are relevant to this week's
    objectives.

  • Any challenges the team encountered and suggest any
    future improvements.

Submit your assignment using the Assignment Files tab above.     Week
5 Individual: Concurrent ProgrammingWrite a
Java program (non-GUI preferred) that has a method named atomic().Demonstrate in
the program how two threads can, sometimes, invoke atomic() concurrently.Create a
second version of the program in which the two threads cannot invoke atomic
concurrently.Submit both
programs using the Assignment Files tab above. To
assist, I have included a demo file of a multi-thread program.  Remember
that the ideal program demonstrates threading in action.    Week
5 Learning Team: Program Improvement IVSelect one program submitted by a team member in
Week Four.Suggest at least 3 ways to improve the selected program. One of these improvements
should be related to the use of thread.Write code and test the
improved program. Deliverables should include:

  • The source code file(s) of the improved program.

  • A 2- to 3-page paper on the approach the team has
    taken to improve the program.

  • Why some of the changes are relevant to this week's
    objectives.

  • Any challenges the team encountered and suggest any
    future improvements.
