Sort the array of string Lexicographically
提问by user4447943
I have an array of string in Java. How do I sort it lexicographically? Is there any built-in function in Collection.sortor Arrays.sort?
我在 Java 中有一个字符串数组。我如何按字典顺序对其进行排序？是否有任何内置功能Collection.sort或Arrays.sort？
For example:
例如：
0) BANANA
1) ANANA
2) NANA
3) ANA
4) NA
5) A
after sorting:
排序后：
5) A
3) ANA
1) ANANA
0) BANANA
4) NA
2) NANA

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

String[] a = { "BANANA", "ANANA", "NANA", "ANA", "NA", "A" };
Arrays.sort(a);

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
您只需查看 javaDocs API 参考以了解如何对数组进行排序。 http://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html
