can you help me with diffence between next and nextline?

Question

I have a LinkedList class in Java, and I need to add to head and add to tail methods with head reference. Everything works fine with integers, but when I try to add String with nextLine() from the Scanner, it adds space as first input. Everything works fine if I input String with next(). Is there some big difference between next and nextLine methods except basic one?

Answer 1

next() is for reading one word, nextLine() reads whole line.
