Java数组排序UTF-8 [英] Java array sort UTF-8
本文介绍了Java数组排序UTF-8的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想对 ArrayList< String>
进行排序,但问题是我的母语字符 - 我的字母是这样的: a,±, b,c,č,d,e,f ... z,ž
。如你所见 z
字符从结尾开始是秒,而±
是字母表中的第二个,所以在我对数组进行排序之后排序不正确。我的所有母语字符都移动到数组的末尾。示例:
I want to sort an ArrayList<String>
but the problem is my native language characters - my alphabet is like this: a, ą, b, c, č, d, e, f ... z, ž
. As you see z
character is second from the end and ą
is second in alphabet, so after I sort my array it is sorted incorrectly. All my native language characters are moved to the end of array. Example:
package lt;
import java.util.ArrayList;
import java.util.Collections;
public class test {
public static void main(String[] args) {
List<String> items = new ArrayList<>();
items.add("bbc");
items.add("ąbc");
items.add("abc");
items.add("zzz");
System.out.println("Unsorted: ");
for(String str : items) {
System.out.println(str);
}
Collections.sort(items);
System.out.println();
System.out.println("Sorted: ");
for(String str : items) {
System.out.println(str);
}
}
}
输出:
Unsorted:
bbc
ąbc
abc
zzz
Sorted:
abc
bbc
zzz
ąbc
应该是:
Sorted:
abc
ąbc
bbc
zzz
推荐答案
你应该使用 Collator class。
You should use Collator class.
例如
Locale lithuanian = new Locale("lt_LT");
Collator lithuanianCollator = Collator.getInstance(lithuanian);
然后使用此整理器对集合进行排序
And then sort the collection using this collator
Collections.sort(theList, lithuanianCollator);
