Answer to Question 1

TRUE

Answer to Question 2

One type of inheritance is interface inheritance. It is a mechanism by which multiple classes share one interface but implement that interface independently of each other or of the parent class. Unlike implementation inheritance, where the subclass inherits both the interface and the functionality of its parent for specialization, the purpose of interface inheritance is to arrive at a subclass that looks exactly like its parent but performs the services its own way.
Besides sharing an interface with other classes, a class might implement multiple interfaces, regardless of whether or not any of the interfaces are shared with others. Multiple interfaces may become necessary for many reasons, including complexity of the services that one class may offer, security to ensure that other entities only see what they are allowed to, multiple functionality, and change when the class must offer new services but must keep the existing contracts in place.
