FileReader总是读取至少一个换行符，即使Java中没有任何换行符

Question

I have this code...

try{
    FileReader fread = new FileReader(new File("testfile"));
    int y = 0;
    while (fread.ready()){
        char path = (char)fread.read();
        System.out.println(path);
        if (path == '\n'){
            y++;
        }
    }
    System.out.println("Newlines: " + y);
}
catch (Exception e){
    System.out.println(e.getMessage());
}

...and a file called testfile containing the following information...

ABC

...and when I run the program it prints out that the file contains one newline. Why is that? I simply cannot find the reason why, having read the Oracle documentation. My problem is easily solved by subtracting one from y, but I am not satisfied with that. This problem drives me crazy since I have no clue where the newline comes from.

(Posted on behalf of the OP) .

My editor (and several else) was adding a newline after eof in the file. Here are pages that list different solutions for different editors:

Gedit adds line at end of file
