第一种情况：

1. Comparator cmp = Collator.getInstance(java.util.Locale.CHINA).
3. String[] arr = { "张三", "李四", "王五", "刘六" }.
4. Arrays.sort(arr, cmp).
5. for (int i = 0. i < arr.length. i )
6. 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//
{
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).
// return collator.compare(((CollationKey) c1).getSourceString(),
// ((CollationKey) c2).getSourceString()).
return collator.compare(((CollationKey) c2).getSourceString(),
((CollationKey) c1).getSourceString()).
}
// public int compare(ComparableBean obj1, ComparableBean obj2) {
// String tempname1 = obj1.getName().
// String tempname2 = obj2.getName().
//
// CollationKey c1 = collator.getCollationKey(tempname1).
// CollationKey c2 = collator.getCollationKey(tempname2).
// return collator.compare(((CollationKey) c1).getSourceString(),
// ((CollationKey) c2).getSourceString()).
// }
}
//the end of ComparableBean.java


测试代码：


ComparableBean[] nameContent = { new ComparableBean("一切从实际出发"),
new ComparableBean("立于不败之地"), new ComparableBean("多项式"),
new ComparableBean("贯彻落实"), new ComparableBean("密切联系群众"),
new ComparableBean("四项基本原则"), new ComparableBean("咬牙切齿"),
new ComparableBean("恭恭敬敬"), new ComparableBean("民警"),
new ComparableBean("经营承包责任制") }.
Arrays.sort(nameContent,new ComparableBeanComparator()).
for (int i = 0. i < nameContent.length. i ) {
System.out.println(nameContent[i].getName()).
}
