Java (pseudocode part # 1 and java code part # 2)

There are 2 parts to this assignment. In the first part, you are going to be given a problem and you will then need to create a structure and write algorithms to solve it. In the second part, youll be turning this algorithm into a java program.

Part 1: Loving your Amoeba Colony!

Your little sister has decided that she wants a pet. You love animals and want to further engender her love of animals, but, well, her last pet, goldie the goldfish, didnt fare too well. So you went on the hunt for a different kind of pet that will fit the bill. Much to your joy, you have found the perfect pet for her an amoeba colony! They are easy to take care of and dont die off too quickly. Now all that you have to do is build a caretaker program so that she can easily take care of her amoebas and see how they thrive (or not!).

Heres what you need for the amoeba colony (hint: these can be be passed/given to the class constructor if you want to challenge yourself):

Colony name Every pet needs a name, right? So youll need to ask the user what the name of their colony is.

Caretaker name Youll need to ask who the colonys mom/dad is.

Starting size How many amoebas is the colony starting out with? This can vary, so you better ask the user about that also.

These are the things that can be done with the colony:

(hint: Do not assume that these must be methods. Think about how they will be used and then decide)

Feed Like all pets, amoebas get hungry. In our case, though, only when they are going to breed. Fortunately, with the program you are building, you can ask the user how many days their colony should be fed and then check to make sure they have enough food to breed (they need 1 day of food for each time they breed).

Breed Other than eating, amoebas dont do much else but breed. Youll want to be sure they have some entertainment, so youll need to ask your user if they want to breed their amoebas and, if so, how many times. For each time they successfully breed, the colony doubles in size. (hint: re-read about feeding)

Vitamins Vitamins can help our amoebas stay healthy. Ask your user if they want to give their colony vitamins.

Sickness Unfortunately, all pets sometimes get sick. When that happens, 10% of the amoebas die off. For every session:

If the colony is NOT given vitamins, it has a 25% chance that it may get sick.

If the colony IS given vitamins, it has a 20% chance that it may get sick.

(hint: you can use the random number generator from Assignment 1 to help you with this)

For this program, youll want to ask your user about any pertinent information up front. Do not worry about having any loops to ask them things like Do you want to feed your colony again? You will only ask them ONCE for the needed information and then tell them how their colony is doing.

For your output (nicely formatted in a JOptionPane), you will want to include:

Colony Name

Caretaker Name

Starting Size

How many times they were fed

Requested number of times to breed

How many times they successfully bred

Whether they got sick and how many died

Final number of amoebas in the colony

For Part 1, create a class structure and algorithms for your AmoebaColony class, and then do several iterations of tests (i.e., analyze it and step through to make sure that it is logically correct). Also write the pseudocode for your tester class (where your main will go). Put these in a Word or Open Office document. Youll turn that document in with the program that you create in Part 2.

Part 2: Creating your Amoeba Colony program

Once you are done writing and testing your class structure and algorithm, you are ready to start coding!

You will need a method that generates a random number again. Heres what you need to do to use it:

i.Include the following code at the top of your class file (so that you can use this class:

import java.util.Random;

To find out more about this, go to http://java.sun.com/javase/7/docs/api/index.html (like you did in Lab Assignment 2)

ii.Youll need to use some variables. Heres how you get a random number:

Random r = new Random();

int x = 1 + r.nextInt(10);

Note that the number in the parens (e.g., 10 above) is the upper limit of the random number. So, the random number that you get here will be an integer between 0 and 10. Need a larger range? Just change the 10 to the top of your range.

Heres another example, in this case if you are printing a random number to the console:

System.out.print( 1 + r.nextInt(5) + " " );

Youll need to use an if-else statement. We havent covered that yet, so heres the structure:

if( variableName1 < variableName2){

// put in what is done if the value of

// variableName is less than the value of

// variableName2

}else{

// put in what is done if the value of

// variableName is greater than or equal to the

// value of variableName2

}

(hint: think about what you need to do with Feed and Breed)

Now start translating your algorithm into java code.

Remember to code and then compile frequently. It will make it easier to find any bugs.

Also remember that you will need to create a tester class (where your main method will reside).

Once you get your program running correctly, there is one more thing to do. Any input requested from the user and/or output received from the user should be in a window (see E.1.14 and E.1.15 from lab 1). At this point, you probably have your output going to the console. For your final submission, it needs to go to a window (JOptionPane). Dont forget any additional libraries that you need to import to do this.

Thats it! Now you can nurture your own amoeba colony, and, chances are, theyll do just fine as your sisters pet! Of course, youll also need to turn it in to Moodle.
