Example

public class ClassA { private BufferedReader reader; public void makeReader (Reader r) { reader = new BufferedReader(r); //do something... } }

Solution

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

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