Exemplo

public class ClassA { public void makeStream (OutputStream oStream) { try { BufferedOutputStream stream = new BufferedOutputStream(oStream); stream.write(7); //executar algo... stream.close(); } catch (IOException e) { //fuga de fluxo... } } }

Solução

Para evitar fugas de recursos, certifique-se de que close() seja chamado em cada java.io.BufferedOutputStream. Nota: Essa regra se aplica a qualquer forma de construtor BufferedOutputStream.

public class ClassA { public void makeStream (OutputStream oStream) { BufferedOutputStream stream = new BufferedOutputStream(oStream); try { stream.write(7); //executar algo... } catch (IOException e) { //executar algo... } finally { if (stream != null) { try { stream.close(); } catch(IOException e) { //executar algo... } } } } }
