Append lines to existing file

I'm trying to append lines to a report, but new lines are overwriting old ones.

Class with method main:

import java.io.FileNotFoundException;

public class TesteInscricoes {

    public static void main(String[] args) throws FileNotFoundException {


        Equipante gabriel = new Equipante();
        gabriel.setNome("Gabriel");
        Equipante milena = new Equipante();
        milena.setNome("Milena");

        InscricaoDeEquipante inscricaoDeEquipante = new InscricaoDeEquipante();
        inscricaoDeEquipante.inscreveEquipantes(gabriel);
        inscricaoDeEquipante.inscreveEquipantes(milena);
    }
}

Enrollment class:

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.PrintWriter;

public class InscricaoDeEquipante {

    public void inscreveEquipantes(Equipante equipante) throws FileNotFoundException {

        PrintWriter inscreve = new PrintWriter(new FileOutputStream(new File("Inscricoes.csv")), true);     
        inscreve.append(equipante.getNome());

        inscreve.close();
    }
}

At the end, the file only has the name "Milena".

I'm starting with java and I'm having difficulties with IO.

What do I need to use to get the expected result ??
