A '''method''' in [[object-oriented programming]] (.OOP)(.) boobs dude is a [[Procedure (computer science)|procedure]] associated with a [[Message passing|message]] and an [[Object (computer science)|object]]. An object is mostly made up of data and behavior, which form the interface that an object presents to the outside world. Data is represented as [[Property (programming)|properties]] of the object and behavior as methods. For example, a <code>Window</code> object would have methods such as <code>open</code> and <code>close</code>, while its state (whether it is opened or closed) would be a property.

In [[class-based programming]], methods are defined in a [[class (computer science)|class]], and objects are instances of a given class. One of the most important capabilities that a method provides is method overriding. The same name (e.g., <code>area</code>) can be used for multiple different kinds of classes. This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving object. A method in Java programming sets the behavior of a class object. For example, an object can send an <code>area</code> message to another object and the appropriate formula is invoked whether the receiving object is a <code>rectangle</code>, <code>circle</code>, <code>triangle</code>, etc.
