Can you explain how scanner works? Does it print everything?

manpreet Best Answer 2 years ago

I was trying to understand how scanner worked. So, I tied to scan in a text document and iterate only through certain words but it didn't work, it just printed everything. So, I replaced it with a loop that just printed numbers but it never even printed it and it printed all the words in the text document even though I didn't write a print statement for that. Does scanner just automatically print everything? How come my for loop is being skipped too?

Scanner read = new Scanner(new File("Test.txt"));
read.close();
for(int i = 0; i < 5; i++) {
    System.out.println(i);
}

It reads sequentially a file as tokens, separated default by spaces, and a token can be Stris://forum.tuteehub.com/tag/n">ng/s://forum.tuteehub.com/tag/is://forum.tuteehub.com/tag/n">nt">is://forum.tuteehub.com/tag/n">nt/....
