First configure your MySQL server to accept remote connections by enabling external connection for MySQL server. Use the IP / hostname of the remote machine in your database connection string, instead of localhost.

Example :

package roseindia.net;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class RemoteMYSQLServer {
        public static void main(String[] args) throws SQLException {
                Connection con = null
                Statement stmt = null; 
                ResultSet rs = null;

                String conUrl = "jdbc:mysql:// 192.168.10.25:3306/";
                String driverName = "com.mysql.jdbc.Driver";
                String databaseName = "student";
                String usrName = "root";
                String usrPass = "root";
                try {
                        // Loading Driver
                        Class.forName(driverName). newInstance();
                } catch (ClassNotFoundException e) {
                        System.out.println(e.toString());
                }
                try {
                        // Getting Connection
                        con = DriverManager.getConnection(conUrl + databaseName, usrName,
                                        usrPass);
                        stmt = con.createStatement();

                        String query = "SELECT * FROM  student'";

                       rs= stmt.executeUpdate(query);
                   if (rs.next()) {
                System.out.println(rs.getString(1));
            }

                } catch (Exception e) {
                        System.out.println(e.toString());
                } finally {
                        // Closing Connection
                        con.close();
                        stmt.close();
                }
        }
}
