程序跳过while循环-没有错误

Question

I have a problem in my Java program. I have a while loop which the program completely skips. I am sure that it skips the while-loop, as I have tested by trying to print out a sentence inside the while loop, which is not executed (neither is the rest of the loop). I don't get an error when i compile or run the program, and I really can't see what's wrong. If anybody could help me, that would be great. I have a while loop extremely similar to this which runs as expected, therefore I find it strange that this one doesn't work.

I will only write the while loop, since my program is very long. This while loop is inside a method (which only contains this loop). (I use easyIO which is similar to Scanner, only a less complex version)

    int i = 0;
    In file = (infile); //Infile is declared earlier in the program 
    int [][] array2D = new int [unique][unique];

    String word1 = file.inWord();

    while (file.hasNext()) {
        String word2 = file.next();
        word1 = word2;
    }

Answer 1

Since you say "infile" is declared earlier in your code, is it possible that you've already iterated through the file earlier in your code? If that's the case, since you're assigning "file" the same reference as "infile" if the pointer is already at the end of the file file.hasNext() will obviously evaluate to false.
