What is a network interface Java?

What is a network interface Java?

This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface. It is used to identify the local interface on which a multicast group is joined. Interfaces are normally known by names such as “le0”.

How does an Ethernet interface work?

Ethernet networking interface refers to a circuit board or card installed in a personal computer or workstation, as a network client. A networking interface allows a computer or mobile device to connect to a local area network (LAN) using Ethernet as the transmission mechanism.

How do I get a list of IP addresses assigned to a network interface?

One of the most useful pieces of information you can get from a network interface is the list of IP addresses that are assigned to it. You can obtain this information from a NetworkInterface instance by using one of two methods. The first method, getInetAddresses() , returns an Enumeration of InetAddress .

How do we address an interface in Java?

To declare an interface, use the interface keyword. It is used to provide total abstraction. That means all the methods in an interface are declared with an empty body and are public and all fields are public, static, and final by default.

It provides total abstraction; means all the methods in an interface are declared with the empty body, and all the fields are public, static and final by default. A class that implements an interface must implement all the methods declared in the interface.

Where interface is used in Java?

An interface in Java is a specification of method prototypes. Whenever you need to guide the programmer or, make a contract specifying how the methods and fields of a type should be you can define an interface.
