I am not sure I entirely understand what you are after – but if you want to print the strings that are “most similar” to your input string first:

You might want to create a Comparator<String> that will compare between 2 strings according to their levenshtein distance from a 3rd string [your input String].

Using this comparator – you can sort your array using Arrays.sort(myArray,new MyCustomComparator(inputString)).

If this is an ArrayList like the title suggest [conflicting title and question body] – you can use Collections.sort(myList,new MyCustomComparator(inputString))
