IO流易错点

Exception in thread "main" java.io.EOFException     at java.io.DataInputStream.readByte(DataInputStream.java:267)     at IO_Data.DataInputStreamTest01.main(DataInputStreamTest01.java:16)

解决方法：更改流的路径即可

错位写法：DataInputStream dis = new DataInputStream(new FileInputStream("Copy02.java"));

正确写法：DataInputStream dis = new DataInputStream(new FileInputStream("src/IO_BufferedReader/Copy02.java"));
