Is it possible to skip EOF when reading input?

php editor Banana is here to answer a common question: "Can EOF be skipped when reading input?" In PHP, EOF refers to "End of File", which is the mark at the end of the file. When we read a file, we usually use a loop to read line by line until we reach the end of the file. However, sometimes we may want to skip EOF and continue reading the next line in certain situations. Fortunately, PHP provides corresponding methods to achieve this requirement. We can use the feof() function to determine whether the end of the file has been reached, and then combine it with the fgets() function to read the next line. In this way, we can skip EOF and achieve flexible file reading operations.

Question content

After I capture the eof, if I try to read information from the input again, I no longer get new information. Is there any way to recover reading data?

Scanner s = new Scanner(System.in);
while (s.hasNextInt()) {
    A[i] = s.nextInt();
    i++;
}

Workaround

If the stream indicates EOF, it means you have consumed it all. There is nothing else to read. If the stream implementation allows it, you can "rewind" the stream and read the same bytes again. Otherwise just close it.

This is similar to eating all the bread. After that there was no bread to eat. Move on and find something else to eat.
