Stop processing in java

I have a processing with one class calling another.

Example:

I have the registry0100 . In it I call ED022 , ED021 , etc ...

In this ED022 , I have some validations, for example:

boolean achou = false;
if (modulo.equals("2")) {
    String[] linhaSeparada = listaParametros.get(5).split(Pattern.quote("|"));
    if (linhaSeparada[0].equals(tipoCnso)) {
        achou = true;
    }
}
if (!achou) {
    apontandoErroAlerta(arquivo, erroAlerta, tipoRegistroCampo, tipoRegistro, erroAlertaEncontradoRepository,
    erroAlertaCampoEncontradoRepository, tipoCnso, contadorLinha, registro, erroAlertaRepository,
    tipoRegistroCampoRepository, tipoRegistroRepository);
        return;
}

If the variable found turns true , it points to the error and should stop the process. But not to.

You should not go to the ED021 error, but it will.

How to stop the process itself.
