Inet6Address equals(Object) in Java

equals(Object): This method is available in the java.net.Inet6Address class of Java.

Syntax:

boolean java.net.Inet6Address.equals(Object obj)

This method takes one argument. This method compares this object against the specified object. The result is true if and only if the argument is not null and it represents the same IP address as this object.

Two instances of InetAddress represent the same IP address if the length of the byte arrays returned by getAddress is the same for both, and each of the array components is the same for the byte arrays.

Parameters: One parameter is required for this method.

obj: the object to compare against.

Returns: true if the objects are the same; false otherwise.

Exceptions: NA

Approach

Java

package com.Inet6Address;

import java.net.Inet6Address;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;

public class Inet6Addressequals {
    public static void main(String[] args) 
          throws UnknownHostException, SocketException {

        String host = "[beingcodeexpert.blogspot.com]";
        byte addr[] = { 12, 34, 56, 1, 3, 4, 5,
                          6, 67, 7, 8, 8, 9, 5, 6, 7 };
        int index = 1;
        NetworkInterface nif = 
                 NetworkInterface.getByIndex(index);
        Inet6Address inet6Address = 
                  Inet6Address.getByAddress(host, addr, nif);
        int scope_id = 1;
        Inet6Address obj = 
               Inet6Address.getByAddress(host, addr, scope_id);

        System.out.println(inet6Address.equals(obj));
    }
}

Output:

true

Some other methods of Inet6Address class

equals(Object): This method compares this object against the specified object. The result is true if and only if the argument is not null and it represents the same IP address as this object.

getAddress(): This method returns the raw IP address of this InetAddress object.

Inet6Address.getByAddress(String, byte[], int): This method creates an Inet6Address in the exact manner of InetAddress.getByAddress(String, byte []) except that the IPv6 scope_id is set to the given numeric value. The scope_id is not checked to determine it corresponds to any interface on the system.

Inet6Address.getByAddress(String, byte[], NetworkInterface): This method creates 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.

getHostAddress(): This method returns the IP address string in textual presentation.

getScopedInterface(): This method would return the scoped interface if this instance was created with a scoped interface.

getScopeId(): This method returns the numeric scopeId if this instance is associated with an interface.

hashCode(): This method returns a hashcode for this IP address.

isAnyLocalAddress(): Utility routine to check if the InetAddress is a wildcard address.

isIPv4CompatibleAddress(): Utility routine to check if the InetAddress is an IPv4-compatible IPv6 address.

isLinkLocalAddress(): Utility routine to check if the InetAddress is a link-local address.

isLoopbackAddress(): Utility routine to check if the InetAddress is a loopback address.

isMCGlobal(): Utility routine to check if the multicast address has global scope.

isMCLinkLocal(): Utility routine to check if the multicast address has link scope.

isMCNodeLocal(): Utility routine to check if the multicast address has node scope.

isMCOrgLocal(): Utility routine to check if the multicast address has organization scope.

isMCSiteLocal(): Utility routine to check if the multicast address has site scope.

isMulticastAddress(): Utility routine to check if the InetAddress is an IP multicast address.

isSiteLocalAddress(): Utility routine to check if the InetAddress is a site-local address.
