That "dummy line/ghost line" in Java

After recalling scanners, I just realized I still don't understand that dummy line/ghost line thing.
...
Which could really screw me over when using .dat files (in CS competitions).



Can anybody explain it please?

Not sure exactly what you're referring to, could you be more specific?

I think I'll experiment it with it later, got other stuffs to do right now

But it had to do something with java scanners when you use both .nextInt() and .nextLine()
(like when you alternate them)

just google it

Wow.


I was just about to prove you that I couldn't find such a answer....

and then one pops up on yahoo answers... of all places ._.
