How can I connect to mariadb using java?

Question

I've used:

Connection  connection = DriverManager.getConnection(
    "jdbc:mysql://localhost:3306/test", "username", "password"
);
Statement stmt = connection.createStatement();
stmt.executeUpdate("CREATE TABLE a (id int not null primary key, value varchar(20))");
stmt.close();
connection.close();

but it gives an error "No route to host"

Java MariaDB example:

//STEP 1. Import required packages
package mariadb;

import java.sql.*;

public class Mariadb {
    // JDBC driver name and database URL

    static final String JDBC_DRIVER = "org.mariadb.jdbc.Driver";
    static final String DB_URL = "jdbc:mariadb://192.168.100.174/db";

    //  Database credentials
    static final String USER = "root";
    static final String PASS = "root";

    public static void main(String[] args) {
        Connection conn = null;
        Statement stmt = null;
        try {
            //STEP 2: Register JDBC driver
            Class.forName("org.mariadb.jdbc.Driver");

            //STEP 3: Open a connection
            System.out.println("Connecting to a selected database...");
            conn = DriverManager.getConnection(
                    "jdbc:mariadb://192.168.100.174/db", "root", "root");
            System.out.println("Connected database successfully...");

            //STEP 4: Execute a query
            System.out.println("Creating table in given database...");
            stmt = conn.createStatement();

            String sql = "CREATE TABLE REGISTRATION "
                    + "(id INTEGER not NULL, "
                    + " first VARCHAR(255), "
                    + " last VARCHAR(255), "
                    + " age INTEGER, "
                    + " PRIMARY KEY ( id ))";

            stmt.executeUpdate(sql);
            System.out.println("Created table in given database...");
        } catch (SQLException se) {
            //Handle errors for JDBC
            se.printStackTrace();
        } catch (Exception e) {
            //Handle errors for Class.forName
            e.printStackTrace();
        } finally {
            //finally block used to close resources
            try {
                if (stmt != null) {
                    conn.close();
                }
            } catch (SQLException se) {
            }// do nothing
            try {
                if (conn != null) {
                    conn.close();
                }
            } catch (SQLException se) {
                se.printStackTrace();
            }//end finally try
        }//end try
        System.out.println("Goodbye!");
    }//end main
}//end JDBCExample

I use this example.I change the bind address to 127.10.230.440. and i restart the server sudo /etc/init.d/mysql start .
