The mediator pattern is a design pattern that promotes loose coupling of objects by removing the need for classes to communicate with each other directly. Builder . Behavioral Design Patterns provide responsibility assignment between instances of classes. By doing so, these patterns increase flexibility in carrying out this communication. Also, they define types of relationships and communication between objects.
