For example i have List with content: {1 5 2b 10 2a 3 7}, and i need sort it in alphabet order as: {1 2a 2b 3 5 7 10}. I tried with Comparator interface as: 

Collections.sort(list);

But it returned array {1 10 2a 2b 3 5 7}. How i can do it in Java?

  • You tried implementing the Comparator interface? Show us the implementation then. The mistake must be in there. Commented Mar 31, 2015 at 14:27
