Java说非空文件是空的？ [英] Java says a nonempty file is empty?

问题描述

我有一个特定文件，说Java是空的......

I have a particular file that Java says is empty...

源代码

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class MinimumWorkingExample
{
    public static void main(String[] args) throws FileNotFoundException
    {
        String filename = "/home/tyson/Data/English-French_test/test/test.f";
        Scanner fileIn = new Scanner(new File(filename));
        System.out.println("***START***");
        while(fileIn.hasNextLine())
        {
            System.out.println(fileIn.nextLine());
        }
        System.out.println("***FINISH***");
    }
}

输出

***START***
***FINISH***

...但该文件不为空：

...but the file is not empty:

问题

为什么会发生这种情况？

Why is this happening???

推荐答案

也可以使用Scanner fileIn = new Scanner（新文件（filename），Cp1252）;因为这是法语的编码，你的系统似乎是UTF-8。
如果扫描程序认为读取UTF-8多字节，则扫描程序可能存在编码问题。

Also do Scanner fileIn = new Scanner(new File(filename), "Cp1252"); as this is the encoding for French, and your system seems to be UTF-8. The Scanner might have encoding problems if it thinks to read UTF-8 multibytes.
