Complete Java SE 8 Developer Bootcamp - The Collection Interface

The video tutorial explores the collection interface and its hierarchy, focusing on the collection class and its subinterfaces for lists, sets, and queues. It explains the role of abstract classes in providing default implementations, allowing developers to override specific methods. The tutorial highlights polymorphism, enabling interchangeable use of collection classes like ArrayList and LinkedList. Key methods in the collection interface, such as add, remove, and size, are discussed, along with converting collections to arrays and vice versa.
