A snippet of Java code with keywords highlighted in blue and bold font. In the Java programming language, a keyword is any one of 68 reserved words [1] that have a predefined meaning in the language. Because of this, programmers cannot use keywords in some contexts, such as names for variables, methods, classes, or as any other identifier. [2]
The active object design pattern decouples method execution from method invocation for objects that each reside in their own thread of control. [1] The goal is to introduce concurrency , by using asynchronous method invocation and a scheduler for handling requests.

The value is then propagated to the server (Line 6) and back to the client (Line 9). On the client, the value of the event are accumulated using the list function and mapped to an HTML list (Line 10). This list is then used in the HTML (Line 16) to display the previous inputs.
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.

Rather, the prototype or parent of an object is just another object to which the object is linked. In Self, an object may have multiple or no parents, [34] but in the most popular prototype-based language, Javascript, every object has one prototype link (and only one). New objects can be created based on already existing objects chosen as their ...
