Beispiel

public class ClassA { public void makeStream (Writer writer) { try { BufferedWriter stream = new BufferedWriter(writer); stream.write(7); //do something... stream.close(); } catch (IOException e) { //stream leaked... } } }

Lösung

Um Ressourcenlecks zu vermeiden, stellen Sie sicher, dass die Methode 'close()' für jedes Vorkommen von 'java.io.BufferedWriter' aufgerufen wird. Hinweis: Diese Regel gilt für jede Form des Konstruktors 'BufferedWriter'.

public class ClassA { public void makeStream (Writer writer) { BufferedWriter stream = new BufferedWriter(writer); try { stream.write(7); //do something... } catch (IOException e) { //do something... } finally { if (stream != null) { try { stream.close(); } catch(IOException e) { //do something... } } } } }
