Example

public class ClassA { private ZipInputStream stream; public void makeStream (InputStream is) { stream = new ZipInputStream(is); //do something... } }

Solution

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

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