FileReader找不到我的文本文件

Question

我有一个简单的文本文件,由于某种原因,它无法找到.我没有看到代码有什么问题,因为我是从网站上得到的,我开始认为我没有将文本文件放在正确的位置.有什么建议吗？

码:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.nio.file.Path;
import java.nio.file.Paths;

public class MainFavorites {
    public static void main(String[] args) throws IOException {
        /**
        * finds pathway to the file
        */
        //      File file = new File("icecreamTopping.txt");
        //      System.out.println(file.getCanonicalPath());

        BufferedReader reader = null;
        ArrayList <String> myFileLines = new ArrayList <String>();
        try {
            String sCurrentLine;
            reader = new BufferedReader(new FileReader("icecreamTopping.txt"));
            while ((sCurrentLine = reader.readLine()) != null) {
                //System.out.println(sCurrentLine);
                myFileLines.add(sCurrentLine);
            }
        } catch (IOException e) {
            e.printStackTrace();
            System.out.print(e.getMessage());
        } finally {
            try {
                if (reader != null)reader.close();
            } catch (IOException ex) {
                System.out.println(ex.getMessage());
                ex.printStackTrace();
            }
        }
        int numElements = myFileLines.size();
        System.out.println ("there are n lines in the file:" + numElements);

        for (int counter = numElements-1; counter >= 0; counter--) {
            String mylineout = myFileLines.get(counter);
            System.out.println (mylineout);
        }
    }
}

文件内容:

1- Blueberry 
2- Banana Buzz
3- Cookie Batter

我的堆栈跟踪是这样的:

java.io.FileNotFoundException: C:\Users\homar_000\workspace\RankFavorites\icecreamTopping.txt (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at MainFavorites.main(MainFavorites.java:28)

Answer 1

替换下面的行

reader = new BufferedReader(new FileReader("icecreamTopping.txt"));

同

reader = new BufferedReader(new FileReader("resources/icecreamTopping.txt"));

并将该文件放在与src文件夹并行的资源文件夹下.

示例代码:

abc.txt从资源文件夹中读取文件

reader = new BufferedReader(new FileReader("resources/abc.txt"));

这是项目结构

尝试下面的代码,找出它指向文件的位置icecreamTopping.txt.

 File f=new File("icecreamTopping.txt");
 System.out.println(f.getAbsolutePath());

获取绝对路径后,只需将文件放在那里.

根据您上次的评论,将icecreamTopping.txt文件RankFavorites直接放入项目中,如下图所示,它肯定会解决您的问题.

Answer 2

发现问题所在了。我没有必要输入文件扩展名，因此我删除了 .txt，因为当我保留它时，它会将其读为“icecreamTopping.txt.txt”
