ThreadSafe detects Java concurrency defects: [2] [3] [4] Race conditions – which lead to incorrect or unpredictable behaviour that is difficult to reproduce in a debugger. Deadlocks [ 7 ] – caused by circular waits between threads waiting for shared resources.
The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming.All execution takes place in the context of threads.Objects and resources can be accessed by many separate threads.
Thread safety guarantees usually also include design steps to prevent or limit the risk of different forms of deadlocks, as well as optimizations to maximize concurrent performance. However, deadlock-free guarantees cannot always be given, since deadlocks can be caused by callbacks and violation of architectural layering independent of the ...
Akka is a source-available toolkit and runtime simplifying the construction of concurrent and distributed applications on the JVM. Akka supports multiple programming models for concurrency, but it emphasizes actor-based concurrency, with inspiration drawn from Erlang. [2] Language bindings exist for both Java and Scala. Akka is written in Scala ...
In a limited beta consumer release in September 2014, [5] Duolingo, Evernote, Sight Words, and Vine Android applications were made available in the Chrome Web Store for installation on Chromebook devices running OS version 37 or higher. [6] In October 2014, three more apps were added: CloudMagic, Onefootball, and Podcast Addict. [7]
For ordered access as defined by the java.util.NavigableMap interface, java.util.concurrent.ConcurrentSkipListMap was added in Java 1.6, [1] and implements java.util.concurrent.ConcurrentMap and also java.util.concurrent.ConcurrentNavigableMap. It is a Skip list which uses Lock-free techniques to make a tree. Performance is O(log(n)).
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
The Pepper API also supports Gamepads (version 19) and WebSockets (version 18). [34] As of 13 May 2010, Google's open source browser, Chromium, was the only web browser to use the new browser plug-in model. [35] As of 2020, Pepper is supported by Chrome, Chromium and Blink layout engine-based browsers such as Opera and Microsoft Edge.
