Can we hack passwords with the help of java

Answer 1

Not really Unless you make a bruteforce app with Java or something.

Answer 2

you need to use an exploit that utilizes java. java update is probably one of the most used methods of gaining access to a remote computer. you set up a payload that uses a java exploit and once the user tries to update java. the connection will be opened and a third party can then connect to it.
for more info on payloads and listeners, look into metasploit framework.
after you have access to a computer, you will need to use various extraction and brute force techniques to get passwords in plain text. but a strong enough password will usually take too long to decrypt and most people won't bother.
having said that, a computer that is saving passwords when you log into a site can be very easily taken advantage of in just a couple of minutes regardless of password strength.
EDIT
This method of exploiting java has been tried and tested by myself and many others before me... I dont appreciate the down vote as my post is the only one here that is actually providing accurate information.
