Example

public class ClassA { private BufferedOutputStream stream; public void makeStream (OutputStream os) { stream = new BufferedOutputStream(os); //do something... } }

Solution

To avoid resource leaks, ensure that close() is invoked on every java.io.BufferedOutputStream. Note: This rule applies to any form of BufferedOutputStream constructor.

public class ClassA { private BufferedOutputStream stream; public void makeStream (OutputStream os) { stream = new BufferedOutputStream(os); //do something... try { stream.close(); } catch(IOException ioe) { //perform exception handling } } }
