The object pool pattern is a software creational design pattern that uses a set of initialized objects kept ready to use – a "pool" – rather than allocating and destroying them on demand. A client of the pool will request an object from the pool and perform operations on the returned object. When the client has finished, it returns the ...
Async/await. In computer programming, the async/await pattern is a syntactic feature of many programming languages that allows an asynchronous, non-blocking function to be structured in a way similar to an ordinary synchronous function. It is semantically related to the concept of a coroutine and is often implemented using similar techniques ...
In Java, the order of initialization is as follows: Invocation of another constructor (either of the object's class or of the object's superclass) Instance variable initializers and instance initializers (in the order they appear in the source code) The constructor body; Like in C#, a new object is created by calling a specific constructor.
Java—thread class or Runnable interface; Julia—"concurrent programming primitives: Tasks, async-wait, Channels." [14] JavaScript—via web workers, in a browser environment, promises, and callbacks. JoCaml—concurrent and distributed channel based, extension of OCaml, implements the join-calculus of processes
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.

The ability to embed Java applets into browsers (starting with Netscape Navigator 2.0 in March 1996 [11]) made two-way sustained communications possible, using a raw TCP socket [12] to communicate between the browser and the server. This socket can remain open as long as the browser is at the document hosting the applet.
