What type of data type would I use for this situation?

Question

I have a class which connects to Oracle, but each connection may be to a different database. Each database has it's own user name and password.
I'd like to pass one key value and then the class would get the user name and password and url from that but not sure how to do it.
Right now, for the function I pass it the url, username, password which then calls a connection function and passes it the same value. This seems messy keep passing values around.
Is there some kind of enumerations or something ?

You might consider putting the URLs, usernames and password into a properties file.
The properties file might contain:
all.databases=database1,database2,database3
database1.user=user1
database1.password=dingbat
database1.url=jdbc:oracle:thin:dohdah:base1
database2.user=someone
database2.password=toad
database2.url=jdbc:oracle:thin:xyx:dsds
Then use ResourceBundle.getBundle() to load the properties and you can just do
Connection con = DriverManger.getConnection(bundle.getString(key + ".url"),bundle,getString(key + ".user"), bundle.getString(key + ".password");
