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//

{

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());

}
