Hi I am newbie to Java. I am using an arraylist to collect string line
input from gui. So my array list is list of strings. I want to sort it.
What is the best way to sort this in ascending order?
Thanks

Arrays.sort() for arrays. Collections.sort() for collections.

l.List)

Thanks both Arrays.sort is what I was looking for. But I still have an
issue with the order in which it sorts.

I have following input

Aa bB Cc
aa bb cc
Aa Bb Cc
Aa bb Cc
Aa bb cc
bb cc aa

and I get the following output

aa bb cc
bb cc aa
Aa bb cc
Aa bb Cc
Aa bB Cc
Aa Bb Cc

But I would like to get
aa bb cc and then
Aa bb Cc

Is there a way to do this in the sort?
'Thanks.

Supply a Comparator that implements the ordering you want.
