Question

I think this may be a duplicate question. But couldn’t find the answer for my requirement.

I have a list of names (String) such as

Merill, Gopi, kamal, orange, white

I need to do something to get the list in ascending order using collections like the following

Gopi, kamal, Merill, orange, white

Is it possible to get the list in alphabeticalorder?

Can anyone please tell how to sort this using collections?

(Please provide a solution before closing this questiona as duplicate)

Answer 1

I know your trying to sort it using Collections, but here’s a simple way:

public static void main(String[] args) throws ParseException {
    String[] values = new String[] {"Some item", "another item", "1 last more", "nevermind", "this is different"};
    System.out.println("Before: " + Arrays.toString(values));
    Arrays.sort(values, new Comparator<String>() {
        @Override
        public int compare(String arg0, String arg1) {
            return arg0.compareTo(arg1);
        }
    });
    System.out.println("After: " + Arrays.toString(values));
}

And this is outputted:

Before: [Some item, another item, 1 last more, nevermind, this is different]

After: [1 last more, Some item, another item, nevermind, this is different]

The array is sorted numerical/other first, then capital-alphabetical, then lowercase-alphabetical
