Default Expire time for Session JAVA

Please clarify my doubt regarding the Cookies and Session......

Cookie will be maintained in Client side. The expire time for this, until we
delete cookies.

But, what is the default expire time for Session.

A session starts the first time a user submits a request to your Servlet,
and it ends either when the user quits his or her browser or when the
session times out which is configurable. So default lifetime for session
is time between first request made and browser closed.
