An easy way to iterate over csv files

Create your model

public class Client {

	private String name;
	private int age;
	
	public String getName() {
		return name;
	}
	
	public void setName(String name) {
		this.name = name;
	}
	
	public int getAge() {
		return age;
	}
	
	public void setAge(int age) {
		this.age = age;
	}
		
}

Create your converter

public class ClientConverter implements CsvDataConverter<Client> {

	public Client convert(CsvFileRow row) {
		
		Client client = new Client();
			
		client.setName(row.get("Name"));
		client.setAge(row.getInt("Age"));
		
		return client;
		
	}
	
	public boolean canHandle(CsvFile file) {
		return file.containsHeaders("Name", "Age");
	}

}

Now you can iterate over an csv file, like this

CsvProcessor<Client> processor = new CsvProcessor<Client>("./clients.csv", new ClientConverter());
	
for(Client client : processor){
	System.out.println(client.getName());
}
	
processor = new CsvProcessor<Client>("./clients.csv", Client.class);
	
for(Client client : processor){
	System.out.println(client.getName());
}
	
Iterator<Client> iterator = new CsvIterator<Client>("./clients.csv", new ClientConverter());
	
while (iterator.hasNext()) {
	Client client = iterator.next();
	System.out.println(client.getName());
}
	
iterator = new CsvIterator<Client>("./clients.CSV", Client.class);

while (iterator.hasNext()) {
	Client client = iterator.next();
	System.out.println(client.getName());
}
