Java 说一个非空文件是空的？

Question

我有一个 particular file Java 说它是空的...

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***

...但文件不为空:

控制台

问题

为什么会这样？？？

Answer 1

也做 Scanner fileIn = new Scanner(new File(filename), "Cp1252");因为这是法语的编码，而您的系统似乎是 UTF-8。 如果 Scanner 想要读取 UTF-8 多字节，它可能会遇到编码问题。
