如何实现mysql数据库连接

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class MySQLConnectionExample {
    public static void main(String[] args) {
        // 设置数据库连接参数
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "myuser";
        String password = "mypassword";
        
        Connection connection = null;
        
        try {
            // 建立数据库连接
            connection = DriverManager.getConnection(url, username, password);
            
            // 执行SQL语句
            // ...
            
            // 处理结果
            // ...
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭连接
            if (connection != null) {
                try {
                    connection.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
