A class is called an object factory because objects are created from the class that contains common attributes and behaviour. The class behaves like a specification for creating such similar objects.
What is called an object factory in Java?
A class is called an object factory because objects are created from a class. An objectis an instance of a class.
What is the use of an object factory Java?
Typically, an object factory is quite simple and small. Its main role is to collect the information necessary to create an instance of the intended object’s class and then to invoke that class’s constructor.
Which is the object maker object factory in Java?
An ObjectFactory is responsible for creating objects of a specific type. In the above example, you may have a PrinterObjectFactory for creating Printer objects. An object factory must implement the ObjectFactory interface.
Which is an object factory?
In object-oriented programming (OOP), a factory is an object for creating other objects – formally a factory is a function or method that returns objects of a varying prototype or class from some method call, which is assumed to be “new”.
Why is a class called a factory of objects write a Java statement to create an object of class Java example?
Answer: A class can create objects of itself with different characteristics and common behaviour just like a factory can produce similar items based on a particular design. Hence, class is also referred to as ‘Object Factory’.
What is the factory class in Java?
Factory method is a creational design pattern which solves the problem of creating product objects without specifying their concrete classes. Factory Method defines a method, which should be used for creating objects instead of direct constructor call ( new operator).
What is the benefit of factory pattern?
Advantage of Factory Design Pattern
Factory Method Pattern allows the sub-classes to choose the type of objects to create. It promotes the loose-coupling by eliminating the need to bind application-specific classes into the code.
What is the purpose of factory pattern?
The stated purpose of the Factory Patterns is: Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.
Why class is called an object factory give an example?
Answer: a) A class is called an object factory because objects are created from a class. … For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a “blueprint” for creating objects.
What is service factory in Java?
ServiceFactory is an abstract class that provides a factory for the creation of instances of the type javax. xml. rpc. … This enables a J2SE based client to create a Service instance in a portable manner without using the constructor of the Service implementation class.
What is the difference between factory method and abstract factory?
The main difference between a “factory method” and an “abstract factory” is that the factory method is a single method, and an abstract factory is an object. The factory method is just a method, it can be overridden in a subclass, whereas the abstract factory is an object that has multiple factory methods on it.
What is a factory in software development?
A software factory is a structured collection of related software assets that aids in producing computer software applications or software components according to specific, externally defined end-user requirements through an assembly process. … Software factories are generally involved with outsourced software creation.
