Examine Enum’s Java documentation and you’ll discover that it overrides java.lang.Object‘s clone(), equals(), finalize(), hashCode(), and toString() methods. Except for toString(), all of these overriding methods are declared final so that they cannot be overridden in a subclass: clone...
Another potential source of these “Java heap space” OOMs arises with the use offinalizers. If a class has afinalizemethod, then objects of that type do not have their space reclaimed at garbage collection time. Instead, after garbage collection, the objects are queued for finalization, which...

Ajava.lang.OutOfMemoryError: Java heap spacecan also occur in applications that use finalizers excessively. If a class has afinalize()method, the GC does not clean up any objects of that class and they are instead queued for finalization, which occurs at a later stage. If the finalizer th...

In this example, we will learn to watch a directory along with all sub-directories and files for changes, using JavaWatchServiceAPI. 1.WatchServiceAPI To RegisterWatchService, get the directory path and usepath.register()method.

If you can do other useful work before worrying about the image, you would probably use multiple threads via the Runnable interface. Our example uses the main thread, since we load only a single image and are willing to wait for it to finish loading. System.out.println ("waiting") ; ...
How to use typesafe enums in switch statements A simple typesafe enum declaration in Java code looks like its counterparts in the C, C++, and C# languages: enumDirection{ NORTH, WEST, EAST, SOUTH } This declaration uses the keywordenumto introduceDirectionas a typesafe enum (a special kind ...
