    private static final String PASSWORD = "s3cr*t";

    public static void main(String[] args) {

            DatabaseMetaData meta = connection.getMetaData();

            // Get system functions supported by database
            String[] functions = meta.getSystemFunctions().split(",\\s*");

            for (String function : functions) {
                System.out.println("Function = " + function);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Here are MySQL database supported system functions.

Function = DATABASE
Function = USER
Function = SYSTEM_USER
Function = SESSION_USER
Function = PASSWORD
Function = ENCRYPT
Function = LAST_INSERT_ID
Function = VERSION
