Example

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

Solution

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

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