我使用eclipse作为我的Java编辑器（我是eclipse的初学者），我想使用这个CSV解析库打开csv：http://opencsv.sourceforge.net/
所以我下载了这些文件并在eclipse中创建了一个新的Java-Project。这些下载文件中有一个示例，当我想启动它时，我收到一条错误消息：“启动错误：选择不包含主类型”
代码有一个主要方法，所以我不知道该怎么做。然后我google了我的问题并阅读建议将示例文件移动到我做的src文件夹中。现在，当我在控制台中运行此代码时，我收到另一条错误消息：“CSVReader无法解析为类型”
以下是我要运行的代码
import com.opencsv.CSVReader;
import com.opencsv.CSVWriter;
import java.io.FileReader;
import java.io.IOException;
import java.io.StringWriter;
import java.util.List;
