用TreeMap实现java中英文排序代码

在中文排序中发现不能正排序，这是字符国际化问题引起的，可以实现ComparaTor接口，使用CollaTor类来解决!

…

import java.text.CollaTor;public class CollaTorComparaTor implements ComparaTor{CollaTor collaTor = CollaTor.getInstance();public int compare(Object element1, Object element2){CollationKey key1 = collaTor.getCollationKey(element1.toString());CollationKey key2 = collaTor.getCollationKey(element2.toString());return key1.compareTo(key2);}}

运行：

TreeMap map = new TreeMap(new CollaTorComparaTor());map.put("1", "1");map.put("华", "华");map.put("花", "花");Collection col = map.values(); 　　IteraTor it = col.iteraTor();while(it.hasNext()){System.out.println(it.next());}

知已知彼，百战百胜。
