How to use Java to check whether a domain exists without any external libraries

You wanted to buy a domain for your personal website. You found a whois service and it told you that your domain is available. You are elated and tried to acquire the domain through your favourite registrar. However, your registrar told you that the domain had already been taken.

Isn’t that frustrating? Well, it happened to me once and I was determined never to use the whois service of those unscrupulous sites ever again.

So how can you check whether a domain name is available by yourself? When you have a computer at hand, you can find several ways to do so. In this post, I share how you can check whether a domain exists with the Java programming without using any external libraries.
