如何使用单个连接执行多个oracle查询？

import java.sql.*;

public class OracleQueryExample {
    public static void main(String[] args) {
        Connection connection = null;
        Statement statement = null;
        ResultSet resultSet = null;

        try {
            // 建立数据库连接
            connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "username", "password");

            // 创建Statement对象
            statement = connection.createStatement();

            // 编写SQL语句
            String query1 = "SELECT * FROM table1";
            String query2 = "SELECT * FROM table2";

            // 执行查询1
            resultSet = statement.executeQuery(query1);
            while (resultSet.next()) {
                // 处理查询结果
                String column1Value = resultSet.getString("column1");
                int column2Value = resultSet.getInt("column2");
                // ...
            }

            // 执行查询2
            resultSet = statement.executeQuery(query2);
            while (resultSet.next()) {
                // 处理查询结果
                // ...
            }

        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭连接和资源
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
                if (statement != null) {
                    statement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}
