while EOF in JAVA?

Question

Following to some forums answers I'm using this:

    while (fileReader.nextLine() != null) {
        String line = fileReader.nextLine();
        System.out.println(line);
    }  

... but it throws exception at the end anyway (Exception in thread "main" java.util.NoSuchElementException: No line found)

Answer 1

Each call to nextLine() moves onto the next line, so when you are actually at the last readable line and the while check passes inspection, the next call to nextLine() will return EOF.

Perhaps you could do one of the following instead:

If fileReader is of type Scanner:

while ((line = fileReader.hasNextLine()) != null) {
    String line = fileReader.nextLine(); 
    System.out.println(line);
}

If fileReader is of type BufferedReader:

String line;
while ((line = fileReader.readLine()) != null) {
    System.out.println(line);
}

So you're reading the current line in the while condition and saving the line in a string for later use.
