Java扫描程序更改字符串 [英] Java Scanner Changing String

问题描述

我正在使用Scanner从文本文件中读取一些基本文件.

I'm doing some basic file reading from a text file using Scanner.

前5个条目是-

 0 MR2Spyder
1 Tundra
3 Echo
3 Yaris
4 ScionxB
4 ScionxD

我通常实例化扫描仪，然后执行此操作-

I instantiate the scanner normally and then do this -

String line = scanner.nextLine();
System.out.println(line);

然后我得到此输出-

ÿþ0 M R 2 S p y d e r 

哪个对我没有意义-Scanner类有问题吗?我应该使用BufferedReader吗?

Which doesn't make sense to me- is there some problem with the Scanner class? Should I be using BufferedReader?

推荐答案

您的文件使用UTF-16进行了编码...字符和标题ÿþ之间的空格表明了这一点-它是 字节顺序标记 .请参见此处:

Your file is encoded using UTF-16... the spaces between characters and the heading ÿþ is indicative of that -- it is the byte order mark. See here:

如果16位单元使用Little-endian顺序，则字节序列将具有0xFF，后跟0xFE.该序列在文本显示中以ISO-8859-1字符ÿþ出现，期望文本为ISO-8859-1.

if the 16-bit units use little-endian order, the sequence of bytes will have 0xFF followed by 0xFE. This sequence appears as the ISO-8859-1 characters ÿþ in a text display that expects the text to be ISO-8859-1.

在构建Scanner 时，必须指定.

You must specify that when constructing your Scanner.

final Scanner scanner = new Scanner(file, "UTF-16");
