| | Method (computer science) - Wikipedia, the free encyclopedia |
 | | An accessor method is a kind of method that is usually small, simple and provides the means for the state of an object to be accessed from other parts of a program. | | | Used mainly in object-oriented programming, the term method refers to a piece of code that is exclusively associated either with a class (called class methods or static methods) or with an object (called instance methods). | | | Like a procedure in procedural programming languages, a method usually consists of a sequence of statements to perform an action, a set of input parameters to parameterize those actions, and possibly an output value (called return value) of some kind. |

| | Interface Sharing |
| | Since the abstract method is visible in the base class it is possible to invoke an abstract method on a derived class object that has been type cast to the base class. | | | While it is not possible to create an object of an abstract class, it is possible, and often done, to have a reference to abstract base classes that refers to an object of a derived, concrete class. | | | If the base class methods are implemented in the base class, then the methods may be overridden in the derived classes. |

| | Abstract class is used if some of the functions are well known and class will grow over time and that is in a project where many of the functionality are unknown, but there existence is base lined. | | | A class that implements the interfaces is bound to implement all the methods defined in Interface. | | | For example - # java.util.Calender is an abstract class with a method getInstance() which # returns an instance of the Calender class. |

| | Method (Java 2 Platform SE v1.4.2) |
| | The string is formatted as the method access modifiers, if any, followed by the method return type, followed by a space, followed by the class declaring the method, followed by a period, followed by the method name, followed by a parenthesized, comma-separated list of the method's formal parameter types. | | | The hashcode is computed as the exclusive-or of the hashcodes for the underlying method's declaring class name and the method's name. | | | If the underlying method is static, the class that declared the method is initialized if it has not already been initialized. |

| | Using Abstract Classes in Visual Basic.NET |
| | In the abstract class you define all the common class members that are needed by all drawing classes. | | | Abstract classes may be thought of as a rather specialized programming tool. | | | Depending on the needs of your project, you may rely on a single abstract class, one or more interfaces, or a combination of an abstract class with an interface. |

| | ABSTRACT CLASSES ================ An abstract class is a class whose sole purpose is to be extended. | | | Problems arise when two superclasses define differing methods or fields with the same name; but this is not the only problem that can occur. | | | Although the List class is abstract, it is an ADT--even without any implementation!-- because it has an interface with public method prototypes and well-defined behaviors. |

| | Writing Abstract Classes and Methods |
| | In this way, an abstract class can define a complete programming interface for its subclasses but allows its subclasses to fill in the implementation details of those methods. | | | Let's look at an example of when you might want to create an abstract class with an abstract method in it. | | | Similarly, in object-oriented programming, you may want to model an abstract concept without being able to create an instance of it. |

| | CS124: Java, Section 4.3 |
| | The subroutines in an interface are abstract methods, which must be implemented in any concrete class that implements the interface. | | | An abstract class is one that is not used to construct objects, but only as a basis for making subclasses. | | | And as with abstract classes, even though you can't construct an object from an interface, you can declare a variable whose type is given by the interface. |

| | Abstract classes vs. interfaces |
| | Choosing interfaces and abstract classes is not an either/or proposition. | | | The base class knows that it needs those methods, but an abstract class lets your class admit that it doesn't know how to perform those actions; it only knows that it must initiate the actions. | | | Many developers forget that a class that defines an abstract method can call that method as well. |

| | An abstract class is a class that cannot be instantiated. | | | My views are -----> We don't need to create objects of abstract classes like- In shape class, we don't know what shape to draw so we havn't provided any implementation of draw in base class shape, but we can provide the implementation specific to derived class like circle or triangle. | | | That is, >we cannot create objects instances from an abstract class. |

| | : PHP Garage => Abstract Class - Method declaration |
| | where is the difference between the signature of a constructor and a method in the following example: | | | Unlike any other method of a subclass, the constructor is designed not to override the method of a base class, but to augment it--i.e.: you would normally (although not always) chain the constructor of a subclass to its parent class, as opposed to completely replacing it. | | | Therefore, requiring a contract for the signature of a constructor would actually be counterproductive to the concept of inheritance, since being able to apply variance to the signature of the constructor is one of the key benefits of creating subclasses. |
