How can I sort this ArrayList the way that I want?

Question

Here is a simple sorting program of an ArrayList:

ArrayList list = new ArrayList();

list.add(\"1_Update\");
list.add(\"11_Add\")         


        

Answer 1

To have Collection.sort() sort arbitrarily you can use

Collections.sort(List list, Comparator c)  

Then simply implement a Comparator that splits the string and sorts first based on the number and then on the rest or however you want it to sort.
