InetAddress equals(Object) in Java

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

Syntax:

boolean java.net.InetAddress.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.

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.InetAddress;

import java.net.InetAddress;
import java.net.UnknownHostException;

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

        byte addr[] = { 1, 2, 3, 4, 5, 6, 7,
                     8, 9, 1, 2, 3, 4, 5, 6, 7 };
        InetAddress inetAddress = InetAddress.getByAddress(addr);

        String host = "[beingcodeexpert.blogspot.com]";

        InetAddress obj = InetAddress.getByAddress(host, addr);

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

Output:

true
