Sort the array of string Lexicographically

Question

I have an array of string in Java. How do I sort it lexicographically? Is there any built-in function in Collection.sort or Arrays.sort?

For example:

0) BANANA
1) ANANA
2) NANA
3) ANA
4) NA
5) A

after sorting:

5) A
3) ANA
1) ANANA
0) BANANA
4) NA
2) NANA

Why not just check the APIs you list? – Dave Newton Jan 17 '15 at 20:18 — Dave Newton, Jan 17 '15 at 20:18

String[] strings = { " Hello ", " This ", "is ", "Sorting ", "Example" };
Arrays.sort(strings);

reverse:

String[] strings = { " Hello ", " This ", "is ", "Sorting ", "Example" };
Arrays.sort(strings, Collections.reverseOrder());

Seems like attribution would be in order; unrelated code is unrelated. – Dave Newton Jan 17 '15 at 20:41

Works fine if input size is minimal, go for comparator – Bytecode Jul 28 '18 at 05:09

You have just to look at the javaDocs API references for how to sort arrays. http://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html
