Homework #1 -- sample code

There are two versions of the instructor's code for homework #1, a simple version and a complicated version. Both versions contain one class, Prime, and a main() method.

The first version is simple; all code is contained in the main() method, and ordinal numbers are printed in a very simple-minded way.

The second version is more complex; it contains a separate static method, buildArrayOfPrimes(), to generate an array of primes, and another static method, ordinal(), to generate the ordinal string (e.g., "first", "23rd") for any non-negative integer argument.

Each version has been placed in an appropriate package (com.bozoid.cis370.hw01.simple and com.bozoid.cis370.hw01.complex, respectively).

Here is the directory structure of the files for this homework, after the complex version has been compiled and javadoced. Note the separation of source files, class files, and documentation, and that the directory structure reflects the package naming.

                           Prime.java

Here are the commands used to build, run, and document the complex version:

cd d:\cis370\code

javac -d classes sources\com\bozoid\cis371\hw01\complex\Prime.java

java -cp classes com.bozoid.cis370.hw01.complex.Prime 1
java -cp classes com.bozoid.cis370.hw01.complex.Prime 3
java -cp classes com.bozoid.cis370.hw01.complex.Prime 4
java -cp classes com.bozoid.cis370.hw01.complex.Prime 77
java -cp classes com.bozoid.cis370.hw01.complex.Prime 8000

javadoc -sourcepath sources ^
   -d .\docs\com\bozoid\cis370\hw01\complex ^
   com.bozoid.cis370.hw01.complex

Here is the result of executing these commands:
