两个java.io.Reader和java.io.FileInputStream不兼容。这是因为FileInputStream使用字节，而Reader是字符流的接口。如果转到https://docs.oracle.com/javase/8/docs/api/java/io/FileInputStream.html，将会看到FileInputStream没有实现Reader。因此，您需要选择使用Reader +他的实现类还是使用FileInputStream。

FileInputStream示例：https://www.mkyong.com/java/how-to-read-file-in-java-fileinputstream/

Reader的一个实现java.io.BufferedReader的示例：How to use Buffered Reader in Java

P.S。请适当关闭所有流。您的fin.close（）;不应在尝试部分中关闭！

祝你好运！
