Java.util.concurrent.LockLock is more object-oriented than the synchronized in the traditional threading model, similar to the lock in life,The lock itself should also be an object. Code fragments executed by two threads to achieve the effect of a synchronous mutex, they must use the same lock object.Lock replacement synchronized　　classOutputer {lock lock=NewReentrantlock (); Public voidoutput (String name) {intLen =name.length (); Lock.lock (); Try{ for(inti = 0;

Thumbnailator is a thumbnail build library that is smoother for the Java interface. By simplifying the thumbnail process from the APIs that provide existing image files and image objects, two or three lines of code can generate thumbnails from existing pictures and allow fine-tuning of thumbnail builds while maintaining the minimum amount of code that needs to be written. It also supports batch generation o

Metrics is a Java library that can provide you with unmatched code-run insight. It was developed by Yammer to detect the health of back-end services on the JVM. Metrics provides a powerful toolset for measuring the behavior of key components in your production environment. Metrics provides a common set of modular libraries for support such as Guice,jetty,log4j,apache httpclient,ehcache,logback,spring, Als
