Inet4Address equals(Object) in Java

equals(Object): This method is available in the java.net.Inet4Address class of Java.

Syntax:

boolean java.net.Inet4Address.equals(Object obj)

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.Inet4Address;

import java.net.Inet4Address;
import java.net.UnknownHostException;

public class Inet4Addressequals {
    public static void main(String[] args) 
                  throws UnknownHostException {

        String host = "beingcodeexpert.blogspot.com";
        Inet4Address inet4Address = 
              (Inet4Address) Inet4Address.getByName(host);

        System.out.println(inet4Address.equals(inet4Address));
    }
}

Output:

true

Some other methods of Inet4Address class

equals(Object): 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.

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

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

isAnyLocalAddress(): Utility routine to check if the InetAddress is a wildcard 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. IP multicast address is a Class D address i.e first four bits of the address are 1110.

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