按字典顺序对字符串数组进行排序

Question

我在Java中有一个字符串数组。我如何按字典顺序排序？ Collection.sort或Arrays.sort中是否有内置函数？

例如：

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

排序后

：

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

Answer 1

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

反向：

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

Answer 2

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

Answer 3

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