In Java, I remember that there was no dbms connection on another PC. What's the problem?

public Connection getConnection(){

        try {  

                String url = "jdbc:oracle:thin:@127.0.0.1:1521:xe"; 
                //url used 127.0.0.1 as a different ip address, so I remember that the connection was not possible.

                String user = "SCOTT"; 
                String password = "TIGER"; 
                conn = DriverManager.getConnection(url, user, password); 
            } } catch (Exception e) { // TODO: handle exception }


        return conn; 
}
