Is there an easy way to convert String to Inetaddress in Java?

I'm trying to convert a string(representing an IP address, e.g. 10.0.2.50) into an InetAddress obj.

According to the API it is possible to create an Object providing a String representing a hostname (e.g. www.google.ch). This is not an option for me since I do not have the hostname for each InetAddress object I want to create(besides that it takes too long).

Is it possible to convert a String (e.g. 10.0.2.50) into an InetAddress obj.? (according to the api it is possible to do so if you have the IP as byte[], but how do I convert a String containing an IP into byte[]?)

Answer 1

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

Answer 2

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.
