Can anyone explain how this example works?

Question

while(it.hasNext())
value= it.next();
s.o.p(value);

Answer 1

not sure but i guess this is reading of a file, so while the variable "it" has lines/content (hasNext()) it will put the line/value in the variable "value" them print in the screen (system.out.print(value)). Did u understand?

Answer 2

somewhat.thanks anyways
