InetAddress toString() in Java

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

Syntax:

String java.net.InetAddress.toString()

This method converts this IP address to a String. The string returned is of the form: hostname / literal IPaddress.If the host name is unresolved, no reverse name service lookup is performed. The hostname part will be represented by an empty string.

Parameters: NA

Returns: a string representation of this IP address.

Exceptions: NA

Approach

Java

package com.InetAddress;

import java.io.IOException;
import java.net.InetAddress;

public class InetAddresstoString {
    public static void main(String[] args) throws IOException {

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

        System.out.println(inetAddress.toString());
    }
}

Output:

/102:304:506:708:901:203:405:607
