Sorry if I wasnt clear in the first place. and I dont understand how the part of the object of the interface what does it mean and when I initialise the object what am I supposed to put in the constructor. Hence, the ADT should work with all elements of a given class E for which we provide an object implementing the Compare Interface. This object should be used to determine the smallest element insert. This is what they ask me to do : the constructor takes as input an object implementing the Compare interface. ** = cable passed from Media Center to Bedroom └─ Work Laptop** (Startech USB-PD Dock) * = cable passed to Bedroom from Media Center ├─ Sony XR65A80K (Google TV) ═══ is Multi-Gigabit ├─ Sony Playstation 4 Notes: └─ UniFi Switch 8 ─────────┬─ UniFi Access Point nanoHD (PoE) (PoE) │ ╠═ Narrative (Cable Matters USB-PD 2.5G Ethernet Dongle) The load factor is a measure of how full the hash table is allowed to get before its capacity is.

It can be used to achieve loose coupling.Īn interface is declared by using the interface keyword.By interface, we can support the functionality of multiple inheritance.There are mainly three reasons to use interface. Since Java 9, we can have private methods in an interface. An interface can be implemented using keyword 'implements'. 7) An abstract class can be extended using keyword 'extends'. An interface can extend another Java interface only. 6) An abstract class can extend another Java class and implement multiple Java interfaces. Since Java 8, we can have default and static methods in an interface. The interface keyword is used to declare interface.

It cannot be instantiated just like the abstract class. Java Interface also represents the IS-A relationship. In other words, you can say that interfaces can have abstract methods and variables.

It is used to achieve abstraction and multiple inheritance in Java. There can be only abstract methods in the Java interface, not method body. The interface in Java is a mechanism to achieve abstraction. It has static constants and abstract methods. Why multiple inheritance is supported in Interface while it is not supported in case of class.Īn interface in Java is a blueprint of a class.
