import java.sql.Statement;

public class MySQLConnection {
    public static void main(String[] args) {
        // 数据库连接信息
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "yourpassword";
        
        // 创建连接
        try {
            Connection conn = DriverManager.getConnection(url, username, password);
            
            // 执行SQL查询
            Statement stmt = conn.createStatement();
            String query = "SELECT * FROM mytable";
            ResultSet rs = stmt.executeQuery(query);
            
            // 处理查询结果
            while (rs.next()) {
                // TODO: 处理每一行数据
            }
            
            // 关闭连接
            rs.close();
            stmt.close();
            conn.close();
