我们如何在java中关闭hsqldb数据库

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

public class CloseHsqldbDatabase {
    public static void main(String[] args) {
        Connection connection = null;

        try {
            // 1. 连接到HSQLDB数据库
            connection = DriverManager.getConnection("jdbc:hsqldb:file:/path/to/database", "username", "password");

            // 2. 执行数据库操作...

        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            if (connection != null) {
                try {
                    // 3. 关闭数据库连接
                    connection.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
