Posta o seu código para enterdemos melhor
De qualquer forma segue um exemplo:
File arquivoDestino = new File("C:\qualquercoisa.txt");
FileWriter writer = new FileWriter(arquivoDestino);
writer.write("Qualquer coisa");
writer.close();
Coloque o texto aonde está escrito Qualquer Coisa e pronto você comuçou a gravar arquivos txt
Não esqueça de circular o código com um try catch para tratar as exceções.
