Pooling is not a new technology, it is more like a software design pattern, the main function is to cache a set of initialized objects, ready to use. In most scenarios, the object pool caches objects that are to
Recently, @szeiger rewrote the implementations of mutable.HashMap and mutable.HashSet here. So far as I see there's no reason not to implement LinkedHashSet/Maps the same way, and in fact doing so will allow LinkedHashMaps/Sets to partic...
HashSet (java.util) HashSet is an implementation of a Set. All optional operations (adding and removing) are supported. JOptionPane (javax.swing) FileUtils (org.apache.commons.io) General file manipulation utilities. Facilities are provided in the following areas: * writing to a Loc...
The unit price of the goods in the mall, the total price that needs to be calculated with the quantity of the goods after the goods are added to the shopping cart. The currency exchange involved with the change of settlement currency type after the payment method is switched in the mall. ...
Java has Hashtable, HashMap, and HashSet 4 and JavaScript has Map. One property of the classical hash table implementations is that they do not provide support for persistence (in the sense of persistent data structures, not persistent storage). They are a place-oriented solution to ...

Binary Search Tree In Java A BST does not allow duplicate nodes. The below diagram shows a BST Representation: Above shown is a sample BST. We see that 20 is the root node of this tree. The left subtree has all the node values that are less than 20. The right subtree has all the ...
∟XSL (Extensible Stylesheet Language) - Implementation in JDK This section provides a tutorial example on how to write a simple program, XSLClassChecker.java, to view implementation classes of XSL (Extensible Stylesheet Language) in JDK.
It's perfectly likely that you might end up needing specialized methods of a LinkedList or LinkedHashSet or LinkedHashMap, for instance, in which case you won't be able to resort to the interface. At least not in Java where there's no compostive datatype declaration syntax and you aren...
