Java address to string

Java Email InternetAddress parse(String addresslist)

Java Email InternetAddress parse(String addresslist) Parse the given comma separated sequence of addresses into InternetAddress objects.

Introduction

Parse the given comma separated sequence of addresses into InternetAddress objects. Addresses must follow RFC822 syntax.

Syntax

The method parse() from InternetAddress is declared as:

public static InternetAddress[] parse(String addresslist) throws AddressException 

The method parse() has the following parameter:

The method parse() returns array of InternetAddress objects

Example

The following code shows how to use InternetAddress from javax.mail.internet.

Specifically, the code shows you how to use Java Email InternetAddress parse(String addresslist)

Java InetAddress toString() Converts this IP address to a String.

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

Syntax

The method toString() from InetAddress is declared as:

public String toString() 

The method toString() returns a string representation of this IP address.

Example

The following code shows how to use InetAddress from java.net.

Specifically, the code shows you how to use Java InetAddress toString()

import java.net.InetAddress; import java.net.UnknownHostException; public class TestGetLocalHost < public static void main(String[] args) < try < InetAddress localhost = InetAddress.getLocalHost(); System.out.println("localhost Unable to set localhost.

How do I convert raw IP address to String?

This example show you how to convert a raw IP address, an array of byte , returned by InetAddress.getAddress() method call to its string representation.

package org.kodejava.net; import java.net.InetAddress; import java.net.UnknownHostException; public class RawIPToString < public static void main(String[] args) < byte[] ip = new byte[0]; try < InetAddress address = InetAddress.getLocalHost(); ip = address.getAddress(); >catch (UnknownHostException e) < e.printStackTrace(); >String ipAddress = RawIPToString.getIpAddress(ip); System.out.println("IP Address = " + ipAddress); try < InetAddress address = InetAddress.getByName("google.com"); ip = address.getAddress(); >catch (UnknownHostException e) < e.printStackTrace(); >ipAddress = RawIPToString.getIpAddress(ip); System.out.println("IP Address = " + ipAddress); > /** * Convert raw IP address to string. * * @param rawBytes raw IP address. * @return a string representation of the raw ip address. */ private static String getIpAddress(byte[] rawBytes) < int i = 4; StringBuilder ipAddress = new StringBuilder(); for (byte raw : rawBytes) < ipAddress.append(raw & 0xFF); if (--i >0) < ipAddress.append("."); >> return ipAddress.toString(); > > 

This example will print something like:

IP Address = 30.30.30.60 IP Address = 142.251.10.113
