Java 文件位置异常

Question

有没有办法在 ENV 中设置目录位置并添加文件名并传递它？

我需要解决我所看到的错误

// I am setting a file in the directory pointed by ENV
String fileLoc = System.getenv("PUBLIC");
System.out.println("File loc is " + fileLoc); // This prints the loc

// File path is passed as parameter
File file = new File(fileLoc + "\\Public Documents\\testFile.txt"); // file is not null. 

// This throws exception C:\Users\Public\Public Documents\testFile.txt 
// (The system cannot find the path specified)
BufferedReader br = new BufferedReader(new FileReader(file));

// when I do this it works 
BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\Public\\Public Documents\\testFile.txt"));

Answer 1

其中一个是

C:\\Users\\Public\\Documents\\testFile.txt

，这是正确的路径，另一个是

C:\Users\Public\Public Documents\testFile.txt

（注意公共和空间的重复）

所以要回答，只需将

File file = new File(fileLoc + "\Public Documents\testFile.txt");

更改为

File file = new File(fileLoc + "\\Documents\\testFile.txt");
