After i return all the values in inputstream,what would inputstream be?empty or something like null?

Question

before i ask user to input another string,i'm sure i have already return the former value of integer.So,i supposed the inputstream to be empty.however,when asking user to input string,i found that i need to write "scanner.nextLine" first.Thus,i guess there must be something existing after i return all the values in inputstream.

hope someone can explain this.
if you have any question about my statement,plz tell me and i will explain again.

thanks!

It would be easier to explain what happens if you published and linked the code your talking about ;)
