Design Pattern based on Encapsulation in Java

Many design pattern in Java uses encapsulation concept, one of them is Factory pattern which is used to create objects. Factory pattern is better choice than new operator for creating object of those classes whose creation logic can vary and also for creating different implementation of same interface. BorderFactory class of JDK is a good example of encapsulation in Java which creates different types of Border and encapsulate creation logic of Border. Singleton pattern in Java also encapsulate how you create instance by providing getInstance() method. since object
is created inside one class and not from any other place in code you can easily change how you create object without
affect other part of code.
