confuse between https:www. ,www, and https:

can any one explain me the exact difference between https://www.domian.com , www.domain.com and https://doamin .com

in google webmaster id add all the three domain in diffrent style and get different info... so anyone help for website and which one should i add in webmaster.

Whatever you choose there should be just one main version that you use. Preferably it's an https version. Doesn't really matter if it's www. or without.

All the other versions should 301 redirect to that main version and that is the version you add on search console (webmaster tools).

There is no difference between the www and non-www. However, the https is a SSL secured protocol (more security for your visitors), a must-have thing especially for e-commerce.

Visit your website in this format: domain.com
And the url that you will get when the website loads is the one that you need to add to the webmaster.
