　第一种情况：

Comparator cmp = Collator.getInstance(java.util.Locale.CHINA);
String[] arr = { "张三", "李四", "王五", "刘六" };
Arrays.sort(arr, cmp);
for (int i = 0; i < arr.length; i++)
System.out.PRintln(arr[i]);

第二种情况：

//ComparableBean.java
import java.text.CollationKey;
import java.text.Collator;
import java.text.RuleBasedCollator;
import java.util.Comparator;

public class ComparableBean{
    private String name;

    public ComparableBean(String name) {

        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}
class ComparableBeanComparator  implements Comparator//<ComparableBean>
{
    RuleBasedCollator collator; // you can set your rules for the instance "collator"
    public ComparableBeanComparator()
    {
        collator = (RuleBasedCollator)Collator.getInstance(java.util.Locale.CHINA);// try testing various locales
    }
    public int compare(Object obj1, Object obj2) {
        String tempname1 = ((ComparableBean) obj1).getName();
        String tempname2 = ((ComparableBean) obj2).getName();

        CollationKey c1 = collator.getCollationKey(tempname1);
        CollationKey c2 = collator.getCollationKey(tempname2);
