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.
A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.

For example, the Unix system time 1 000 000 000 seconds since the beginning of the epoch translates into the calendar time 9 September 2001 01:46:40 UT. Library subroutines that handle such conversions may also deal with adjustments for time zones , daylight saving time (DST), leap seconds, and the user's locale settings.

In some languages, for example C++, Java, and Raku this or self is a keyword, and the variable automatically exists in instance methods. In others, for example, Python, Rust, and Perl 5, the first parameter of an instance method is such a reference. It needs to be specified explicitly.
While the library classes java.util.Observer and java.util.Observable exist, they have been deprecated in Java 9 because the model implemented was quite limited. Below is an example written in Java that takes keyboard input and handles each input line as an event.
Various utility templates used to compute dates and time values. Despite their internal design, they are built for maximum reusability in various contexts, so the syntax to use them is very simple, and each of these templates is documented with examples of use and return values.
