Typesafe enums offer a better alternative to Java's traditional enumerated types. Here's how to use typesafe enums correctly in your Java code.
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...

The program (may be part of Garbage collector), which calls this (finalize) method mast not be in the same package (that is java.jang) nor it is a subclass of the class (whose finalize method it calls). Then how the finalize method is getting called by the garbage collector when it...
If the image is stored locally on the machine (typical for applications) you use the default Toolkit object to load the image file. The Toolkit.getImage method receives one parameter (the filename) and begins loading the image file into a new Image object. The preceding example shows a simpl...
