Uses of Class java.net.NetworkInterface (Java SE 12 & JDK 12 )

Packages that use NetworkInterface
Package	Description
java.net	Provides the classes for implementing networking applications.
java.nio.channels	Defines channels, which represent connections to entities that are capable of performing I/O operations, such as files and sockets; defines selectors, for multiplexed, non-blocking I/O operations.

Uses of NetworkInterface in java.net

Fields in java.net with type parameters of type NetworkInterface
Modifier and Type	Field	Description
`static SocketOption<NetworkInterface>`	StandardSocketOptions.`IP_MULTICAST_IF`	The network interface for Internet Protocol (IP) multicast datagrams.

Methods in java.net that return NetworkInterface
Modifier and Type	Method	Description
`static NetworkInterface`	NetworkInterface.`getByIndex(int index)`	Get a network interface given its index.
`static NetworkInterface`	NetworkInterface.`getByInetAddress(InetAddress addr)`	Convenience method to search for a network interface that has the specified Internet Protocol (IP) address bound to it.
`static NetworkInterface`	NetworkInterface.`getByName(String name)`	Searches for the network interface with the specified name.
`NetworkInterface`	MulticastSocket.`getNetworkInterface()`	Get the multicast network interface set.
`NetworkInterface`	NetworkInterface.`getParent()`	Returns the parent NetworkInterface of this interface if this is a subinterface, or `null` if it is a physical (non virtual) interface or has no parent.
`NetworkInterface`	Inet6Address.`getScopedInterface()`	Returns the scoped interface, if this instance was created with a scoped interface.

Methods in java.net that return types with arguments of type NetworkInterface
Modifier and Type	Method	Description
`static Enumeration<NetworkInterface>`	NetworkInterface.`getNetworkInterfaces()`	Returns an `Enumeration` of all the interfaces on this machine.
`Enumeration<NetworkInterface>`	NetworkInterface.`getSubInterfaces()`	Get an Enumeration with all the subinterfaces (also known as virtual interfaces) attached to this network interface.
`static Stream<NetworkInterface>`	NetworkInterface.`networkInterfaces()`	Returns a `Stream` of all the interfaces on this machine.
`Stream<NetworkInterface>`	NetworkInterface.`subInterfaces()`	Get a Stream of all subinterfaces (also known as virtual interfaces) attached to this network interface.

Methods in java.net with parameters of type NetworkInterface
Modifier and Type	Method	Description
`static Inet6Address`	Inet6Address.`getByAddress(String host, byte[] addr, NetworkInterface nif)`	Create an Inet6Address in the exact manner of `InetAddress.getByAddress(String,byte[])` except that the IPv6 scope_id is set to the value corresponding to the given interface for the address type specified in `addr`.
`boolean`	InetAddress.`isReachable(NetworkInterface netif, int ttl, int timeout)`	Test whether that address is reachable.
`protected abstract void`	DatagramSocketImpl.`joinGroup(SocketAddress mcastaddr, NetworkInterface netIf)`	Join the multicast group.
`void`	MulticastSocket.`joinGroup(SocketAddress mcastaddr, NetworkInterface netIf)`	Joins the specified multicast group at the specified interface.
`protected abstract void`	DatagramSocketImpl.`leaveGroup(SocketAddress mcastaddr, NetworkInterface netIf)`	Leave the multicast group.
`void`	MulticastSocket.`leaveGroup(SocketAddress mcastaddr, NetworkInterface netIf)`	Leave a multicast group on a specified local interface.
`void`	MulticastSocket.`setNetworkInterface(NetworkInterface netIf)`	Specify the network interface for outgoing multicast datagrams sent on this socket.

Uses of NetworkInterface in java.nio.channels

Methods in java.nio.channels that return NetworkInterface
Modifier and Type	Method	Description
`abstract NetworkInterface`	MembershipKey.`networkInterface()`	Returns the network interface for which this membership key was created.

Methods in java.nio.channels with parameters of type NetworkInterface
Modifier and Type	Method	Description
`MembershipKey`	MulticastChannel.`join(InetAddress group, NetworkInterface interf)`	Joins a multicast group to begin receiving all datagrams sent to the group, returning a membership key.
`MembershipKey`	MulticastChannel.`join(InetAddress group, NetworkInterface interf, InetAddress source)`	Joins a multicast group to begin receiving datagrams sent to the group from a given source address.
