Help! Weird Vector and Sort

Question

Hi
i was using java.util.Collections.sort(v); where v hold the lists of integers
and it did not sort properly at all.
what happen is my data file had the following
12 43 33
43 123 44
88
55
42
this will sort double digits in order, but not third digits.
this is will sort like this
12 123 33 42 43 43 44 44 88
that number 123 supposed to be last.
is that mean java.util.Collections.sort only sort double digits?
is there other way to fix it?
thanks a bunch!

Answer 1

but it give me error that it is not allowed, so howdo
i conevenet each string stored to integers?That wasn't the error message, was it? Why didn't you
post the exact error message? Anyway, the answer is
that you can only store objects in a vector. And
Integer.parseInt() returns an int, which is a
primitive type and not an object. So you need to
store Integer objects, not ints, in your vector. So
use Integer.valueOf(whateveryourstringwas) instead,
which returns an Integer. And spend a minute looking
at the API documentation to see just what it does.you are right:) i see the difference object and primitive types:) now it is working sighhh
thanks!!
