1. STANDARD DESIGN FACTORY IN JAVA https://www.besanttechnologies.com/training-courses/java-training

2. one of the main design patterns that are intensively used not only in the JDK, but also in several open source structures, • such as Spring, Struts and Apache, • together with the design standard of decoration in Java The pattern of factory design is based on the concept of object-oriented encapsulation. • The factory method is used to create an object other than the factory, it is usually called Element and it encapsulates the creation code, so, • instead of having an object creation code on the client side, we encapsulate the Factory method. in Java.

3. One of the best examples of factory pattern in Java is the BorderFactory class of Swing API. • In this tutorial design pattern, see what is the factory default design method in Java, which are the main advantages of the default factory pattern in Java Example of factory pattern code and What is the default factory default in Java or when using the factory design standard? • This article is following my standard design article as 10 OOPS and the design principles that the Java SOLID programmer should know and how to use the Observer standard in JavaO which is the static factory method or factory design pattern: STANDARD DESIGN FACTORY IN JAVA

4. The factory design pattern is used to create objects or classes in Java and provides flexible and high cohesion coupling. • The factory pattern encapsulates the creation logic of the object, which facilitates the change later when the created object is changed or can even insert a new object with only one change in a class. GOF, the factory default is shown as the standard design. • The factory must be an interface and customers first create the factory or obtain the factory that they then used to create objects.

5. METHOD EXAMPLE Static factory in JDKO The best example of the standard factory creation method is the valueOf () method, which is present in the string and wrappers of classes such as Integer and Boolean and used for the type conversion, • ie the conversion of type string for Integer or String for double in java. STANDARD DESIGN FACTORY IN JAVA

6. SOME OTHER EXAMPLES OF STANDARD DESIGN METHOD IS FACTORY JDK • method valueOf () returns the object created by the factory equivalent value of the parameter passed.methodgetInstance (), • which creates an instance of the class Singleton. • newInstance method () that is used to create and return new factory instance method each time it is named.getType () and NewType () equivalent factory method getInstance () and newInstance (), • but it is used when the factory method resides in a separate class.

7. That is resolved by the Factory Pattern method in Java Whenever we speak of object-oriented language, it will be based on some concepts such as abstraction, • polymorphism, etc. • and encapsulation and delegation, important concepts will be designated as good if the tasks are delegated to different objects and some type of encapsulation is present.

8. Sometimes our application or structure does not know what type of object it has to create execution time if only knows the interface or abstract class and since we know that we can not create an interface object or abstract class, • the main problem is that the framework knows when to create but does not know what type of object we create the object using new () , • we have violated the programming principle for the interface, instead of the implementation, • which eventually results in inflexible code and is difficult to change in maintenance. • Using the factory design pattern in Java, we eliminate this problem.

9. Another problem we can face is that the class needs to contain objects of other classes or hierarchies of classes within it; This can be easily obtained using only the new keyword and the class constructor. • The problem with this approach is that it is a very difficult approach to create objects, since this creates dependency between the two classes. STANDARD DESIGN FACTORY IN JAVA

10. Thus, the factory pattern solves this problem very easily by modeling an interface to create an object that at the time of the creation allows its subclasses to decide what type of instance, the Factory Pattern promotes flexible coupling, eliminating the need to link specific classes of the application in the code. • Factory methods are usually implemented as virtual methods, so this pattern is also called "Virtual Generator".

11. These methods create the objects of the products or of the target classes. When using the factory design pattern in JavaO, the Static Factory methods are common in structures in which the library code needs to create objects of types that can be subclassified. for the applications that use the structure. Some or all. STANDARD DESIGN FACTORY IN JAVA
