In this mini Fragment, we introduce Joshua's seventh Item and a momentous end to the first chapter: Avoid finalizers Stay tuned for more items from our "Effective Java for Android developers" Fragment series. Show Notes Effective Java (2nd Edition) - Joshua Bloch Avoid finalizers If you don't know what they are, ignorance is bliss. If you know what they are, avoid them! Finalizers in Java != destructors in C++ (C++ counterparts to constructors). In C++ destructors you reclaim resources here (Java has GC) you also reclaim non-memory resources (use the try-finally block in Java) (unpredicatable amt of time between object becoming unreachable and finalizer being executed) Never do anything time critical in finalizer! System.gc + System.runFinalization increase chances - no guarantee System.runFinalizersOnExit + Runtime.runFinalizersOnExit are the ones that do - but they are fatally flawed Java 7 has try with resources, which is also interesting and auto-closeables. [Android] devs can only dream of these. If an uncaught exception is thrown in a finalizer, it is ignored, and the finalization abruptly terminates. Severe performance penalty for using finalizers - (one e.g.) time to create and destroy simple object goes from 5.6ns -> 2400ns Only valid use: as a safety net or to terminate noncritical native resources. [Android] you're probably better off using Android's lifecycle methods. Contact @fragmentedcast [twitter.com] @donnfelker [twitter.com] @kaushikgopal [twitter.com]

Singer and Android developer Donn Felker explores Joshua Bloch's fourth Item: Enforce noninstantiability with a private constructor. Stay tuned, cause we got more of these quick ones coming. Effective Java (2nd Edition) - Joshua Bloch Enforce noninstantiability with a private constructor. Examples where you don't want class to be instantiated class that groups static methods and static fields (Util like classes think java.lang.Math/java.util.Arrays) class that groups static methods (including factory methods) for objects implementing specific interfaces (think java.util.Collections) class that group methods on a final class (vs. extending the class) Considerations Makes no sense to instantiate such "Util" classes Private constructors prevent instantiation Important side effect: prevents subclassing Contact us: @fragmentedcast [twitter.com] @donnfelker [twitter.com] @kaushikgopal [twitter.com]
