Java code ( 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.
