Create Project Directory

To help keep our project1 code and other files organized, first create a project directory, which will eventually contain all of your source and test code for your project along with other documents. If your section required GitHub repos for submissions, your project directory would go within the repo directory.

Reminder

If your section required GitHub repos for submissions, your project directory would go within the repo directory. You will clone the repo and move into the repo directory prior to creating project directory. For example, pwd would result in /afs/unity.ncsu.edu/users/j/jtking/csc116/
csc116-001-LabX-01/Paycheck where your cloned repo is csc116-001-LabX-01.

For example:

% pwd
/afs/unity.ncsu.edu/users/j/jtking/csc116

% mkdir Paycheck

% ls
Paycheck

% cd Paycheck
% pwd
/afs/unity.ncsu.edu/users/j/jtking/csc116/Paycheck

Project Structure

Within the project directory, we will create the following directories, which will help organize and separate your files into:

  • src (source) code,
  • test (test) code,
  • lib (library) files,
  • bin (compiled .class) files,
  • doc (generated Javadoc) files, and
  • project_docs (project document) files (e.g., Black Box Test Plan)
Paycheck
    -> src  (directory will contain your source code)
    -> test (directory will contain your test code)
    -> lib  (directory will contain your JUnit library file)
    -> bin  (directory that will contain all of your .class files)
    -> doc  (directory that will contain all of your Javadoc files)
    -> project_docs (directory that will contain all of your project documents, e.g., Black Box Test Plan)

Place Paycheck.java in src

We will place Paycheck.java into src directory.

Our directory structure2 will be:

Paycheck
    -> src
        -> Paycheck.java
    -> test
    -> lib
    -> bin
    -> doc
    -> project_docs

Compile Code

Assuming you are currently in your top-level project directory (Paycheck), then compile your source code using the following command:

javac -d bin src/Paycheck.java

The -d argument tells Java the destination directory that it should save the compiled .class files into. Here, we tell Java to save the .class files into the bin directory.

Execute Code

Now that we have compiled the source code, your directory structure should currently look like:

Paycheck
    -> src 
        -> Paycheck.java
    -> test
    -> lib 
    -> bin
        -> Paycheck.class
    -> doc
    -> project_docs

When we execute Java programs, we are actually executing the .class files.

To execute the Paycheck program, make sure you are in your top-level project directory (Paycheck) and use the following command:

 java -cp bin Paycheck

The -cp argument tells Java the classpath where the compiled .class files are located. Here, we tell Java that the .class files are in the bin directory.

Footnotes

  1. Throughout the Testing materials, the term “project” refers to any program assignment, including projects and exercises. ↩

  2. To view the contents of a directory along with the contents of its subdirectories, you can use the -R option of ls: ls -R ↩
