Question

I am using the following java code to sort the values: –

 Collections.sort(values);

It is working correctly except that it is sorting as follows: –
1 10 2 3 4

I need it to sort as follows: –
1 2 3 4 10

Answer 1

You are sorting Strings. You can change values to store a subclass of Number or implement your own Comparator to pass as the segment argument of the sort method which will do a “natural sort.”

See this question for more details: Natural sort order string comparison in Java – is one built in?
