this question has answer here:

i have connection pool. in getconnection() method poll connection queue variable , check whether closed isclosed() method. if closed set variable new connection drivermanager.getconnection(url, user, password) method.

the question is: need close connection mannualy close() method before rewriting varible ensure connection collected garbage collector?

if call close() manually after connection has been closed, there no action performed on connection object.
