This repository is for the assignment "Clean up ClassDivider" for Programming Methods, a course at the TU/e.

Classdivider

Classdivider divides a class of students into groups of a given size, +/- a given deviation. For example, to divide the example class listed in students.lst into groups of 4 +/- 2 students, run classdivider as follows:

java -jar target/classdivider-0.6.jar -g 4 -d 2 students.lst

Usage

Usage: classdivider [-hV] [-d=<deviation>] -g=<groupSize> <studentsFile>
Divide a class of students into groups.
      <studentsFile>   path to file with students data in CSV format
  -d, --deviation=<deviation>
                       permitted difference of number of students in a group
                         and the preferred group size. Defaults to 1.
  -g, --group-size=<groupSize>
                       preferred group size.
  -h, --help           Show this help message and exit.
  -V, --version        Print version information and exit.

Building and running classdivider

Because classdivider uses two external libraries, one for reading CSV files and one to make nice command-line interfaces, you need to package the dependencies when building the program.

On the terminal, run:

mvn clean compile assembly:single

This actions creates Jar file target/classdivider-0.6.jar.

We created a "Maven action" for this in NetBeans called build. So, you can build this project with all dependencies also via the project context menu Run Maven → build.

After building the program, you run it in a terminal. In the terminal, change directory to the project's root directory and run:

java -jar target/classdivider-0.6.jar -g 4 -d 2 students.lst
