Answer 1

DriverManager#getConnection it self attempts to establish a connection to the given database URL. The DriverManager attempts to select an appropriate driver from the set of registered JDBC drivers. and thorws SQLException if a database access error occurs.

you can test you connection is valid or not with Connection#isValid(int timeout) returns true if the connection has not been closed and is still valid.

...
Connection conn = DriverManager.getConnection(url, username, password);
boolean reachable = conn.isValid(10);// 10 sec
