Translating the implicit this into an explicit parameter, the call (in B, with a a delegate) a.foo() translates to A.foo(b), using the type of a for method resolution, but the delegating object b for the this argument. Using inheritance, the analogous code (using capital letters to emphasize that resolution is based on classes, not objects) is:
In the delegate pattern, this is instead accomplished by explicitly passing the original object to the delegate, as an argument to a method. [1] " Delegation" is often used loosely to refer to the distinct concept of forwarding , where the sending object simply uses the corresponding member on the receiving object, evaluated in the context of ...

In Java, several factories are used in the javax.xml.parsers package, such as javax.xml.parsers.DocumentBuilderFactory or javax.xml.parsers.SAXParserFactory. In the HTML5 DOM API, the Document interface contains a createElement() factory method for creating specific elements of the HTMLElement interface.
A class diagram exemplifying the singleton pattern.. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
The Visitor [1] design pattern is one of the twenty-three well-known Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.

Although reserved as a keyword in Java, goto is not used and has no function. [2] [26] strictfp (added in J2SE 1.2) [4] Although reserved as a keyword in Java, strictfp is obsolete, and no longer has any function. [27] Previously this keyword was used to restrict the precision and rounding of floating point calculations to ensure portability. [8]
