1. Standard Methods

A new inclusion to the Java terminology, you can now add technique systems to connections (called default methods). These techniques are unquestioningly included to every category which utilizes the interface.

This allows you to add performance to current collections without splitting rule. That’s definitely a plus. The other part is that this seriously blurs the range between an interface, which is intended to provide as an agreement, and a category which provides as its tangible execution. In the right arms this can be a stylish way to make connections wiser, prevent repeating and increase collections.

  1. Procedure Termination

Launching an exterior process is one of those techniques you do half-knowing you’ll come returning to debug it when the procedure accidents, dangles or takes in 100% CPU. The Procedure category now comes prepared with two new techniques to help you take management of wild procedures.

The first one, isAlive(), allows you quickly examine if the procedure is still up without having to delay for it. The second and more highly effective one is destroyForcibly() which allows you intentionally destroy an activity which has timed-out or is no more necessary.

  1. Stamped Locks Now here’s something to get thrilled about. Nobody prefers to connect rule. It’s a sure-fire way of decreasing your app’s throughput (especially under scale), or more intense – cause it to hold. Even so, sometime you just don’t have a option.

There are a lot of idioms to connect multi-threaded accessibility a source. One of the most venerated ones is ReadWriteLock and its associated implementations. This idiom is intended to decrease argument by enabling several discussions to eat a source while only preventing for discussions that operate it. Appears to be excellent theoretically, but actually this secure is slow, especially with a large variety of author discussions.

This got so bad that Java 8 is presenting a product new RWLock known as StampedLock. Not only is this secure quicker, but it also provides a highly effective API for positive securing, where you can acquire a audience secure at a very low price, expecting that no create function happens during the crucial area.

  1. Contingency Adders

This is another little gem for anyone operating on multi-threaded applications. A easy and effective new API for studying and composing to surfaces from several discussions, in a way that’s even quicker than using Atomic Integers. Really cool!
