	// The "name" field is mapped to a column in CSV named "name"
	@CsvColumn("name")
	private String name;
	// The "race" field is mapped to a column in CSV named "race"
	@CsvColumn("race")
	private String race;

		return "Dog{" +
				"name='" + name + '\'' +

				", proprietary='" + proprietary + '\'' +
				'}';

}

Create the engine

CsvEngine engine = new CsvEngine(Dog.class);

Read a CSV File

List<Dog> dogs = engine.parseInputStream(csvFile, Dog.class).getObjects();

Write a CSV File

engine.writeFile(writer, dogs, Dog.class);

Read a CSV File and handle each row

engine.parseFileAndInsert(new InputStreamReader(stream), Dog.class, new InsertObject<Dog>() {
	@Override
	public void insertObject(Dog dog) {
		System.out.println(dog.toString());
	}
});
