when use web browser submit login, you're interacting server. web browser submits post request containing login information (like username , password), , server responds next webpage load.

the details of going depend on website you're interacting with. websites might use ajax submit data , trigger javascript run.

the point is, you're going have understand how underlying web server , webpage works. you're going have use rules of interactions issue appropriate requests processing code.

it might simple submitting login credentials in url , scraping information webpage.

more likely, you're going have interact kind of web api , requests yourself. google "java post request" more info.

of course, of assumes website open people using it. if website isn't yours, locked down , unavailable you.
