这段代码连接abd创建了一个数据库，如何选择创建的数据库来使用它？

public class Connect {

    public static void main(String[] args) {
        Connection connection = null;
        try {
            Class.forName("org.postgresql.Driver");
            connection = DriverManager.getConnection(
            "jdbc:postgresql://localhost:5432/","postgres", "12345");


            Statement statement = connection.createStatement();
            statement.execute("CREATE DATABASE mydb");
            //now I hav to connect to mydb

            connection.close();
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(OracleToPostgres.class.getName()).log(Level.SEVERE, null, ex);
        } catch (SQLException ex) {
            Logger.getLogger(OracleToPostgres.class.getName()).log(Level.SEVERE, null, ex);
        }   
    }
}
