            // Get the information of maximum concurrent connection to the
            // database. The maximum number of active connections possible
            // at one time; a result of zero means that there is no limit
            // or the limit is not known.
            int maxConnection = metadata.getMaxConnections();

}

The result of the code snippet above:

Maximum Connection = 0
