Example

public class ClassA { private InputStreamReader reader; public void makeReader (InputStream is) { reader = new InputStreamReader(is); //do something... } }

Solution

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

public class ClassA { private InputStreamReader reader; public void makeReader (InputStream is) { reader = new InputStreamReader(is); //do something... try { reader.close(); } catch(IOException ioe) { //perform exception handling } } }
