问题：
使用java语言，实现一个Hadoop程序，使用Hive进行复杂查询和数据筛查。
解答思路：
要在Java中使用Hadoop和Hive实现一个复杂查询和数据筛查，需要完成以下步骤：
1. 准备Hadoop和Hive环境。
2. 创建一个Hive数据库和表。
3. 编写Java程序来执行Hive查询。
下面是一个简单的示例：
步骤1: 准备Hadoop和Hive环境
确保已经安装了Hadoop和Hive，并且Hive服务正在运行。
步骤2: 创建Hive数据库和表
首先，使用Hive CLI或HiveQL在Hive中创建一个数据库和表。以下是一个简单的例子：
CREATE DATABASE IF NOT EXISTS mydatabase;USE mydatabase;CREATE TABLE IF NOT EXISTS sales (id INT,amount DOUBLE,date STRING) ROW FORMAT DELIMITEDFIELDS TERMINATED BY '\t'STORED AS TEXTFILE;步骤3: 编写Java程序
下面是一个Java程序的片段示例，它使用Hive执行查询：
