如何从java关闭MySQL服务器

import java.sql.*;

String url = "jdbc:mysql://localhost:3306/mydatabase";
String username = "root";
String password = "password";

Connection connection = DriverManager.getConnection(url, username, password);

Statement statement = connection.createStatement();

String sql = "SHUTDOWN";
statement.execute(sql);

statement.close();
connection.close();

import java.sql.*;

public class CloseMySQLServer {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try {
            Connection connection = DriverManager.getConnection(url, username, password);
            Statement statement = connection.createStatement();

            String sql = "SHUTDOWN";
            statement.execute(sql);

            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
