This is a concurrent class library developed by Rice University, not very popular, but it's more useful, GitHub addressThe following is a brief introduction:PCDP is a shared-memory, pedagogical, parallel programming framework. PCDP ' s design, implementation, and APIs emphasize simplicity to make it straightforward to use for programmers new to Parallel programming. PCDP supports task parallelism, loop parallelism, actor parallelism, bulk synchronizat

Good things to share to recommend, here to recommend a Java platform under the open-source diagram of the library Jfreechart, related resources (source code, demo source, development Guide) has been uploaded to the CSDN resources, need to download them yourself.Jfreechart's charting capabilities are very powerful, covering almost any chart you want, and it's cool to draw. Look at the main jfreechart:Before

Bouncy Castle is a lightweight, open-source cryptographic package for the Java platform. It supports a large number of cryptographic algorithms and provides the implementation of JCE 1.2.1. Since bouncy Castle is designed to be lightweight, it can be run from J2SE 1.4 to J2ME (including MIDP) platforms. It is the only complete cryptographic package that runs on MIDP.Also available in the C # version of theAddress: http://www.bouncycastle.org/csharp/

The difference between Collection and collections in Http://www.cnblogs.com/dashi/p/3597937.htmlJava 1, Java.util.Collection is aCollection Interface (a top-level interface of a collection Class)。 It provides a common interface method for basic manipulation of collection objects. The collection interface has many specific implementations in the Java class Library.The meaning of the collection interface is to provide a maximum unified operation for a v

That indicates which of the observers sent the notification. ARG: The content that needs to be observed. the object to be observed by the observer is the class that inherits from the observable. You must call the Super.setchanged () method and the Notifyobservers (XXX) method when sending notifications. This design pattern is a mechanism of
