Java编程中怎样实现中文排序

Posted 2023-04-17

简单的实现排序，可以参考如下的代码

import java.text.Collator;
import java.util.Arrays;
import java.util.Comparator;
import java.util.Locale;

public class PYDemo 
public static void main(String[] args) 
String[] names= "赵z子z龙l","刘l备b","关g羽y","张z飞f";
System.out.println("排序前"+Arrays.toString(names));
Comparator cpt = Collator.getInstance(Locale.CHINA); 
Arrays.sort(names, cpt);
System.out.println("排序后"+Arrays.toString(names));

测试输出

排序前[赵z子z龙l, 刘l备b, 关g羽y, 张z飞f]
排序后[关g羽y, 刘l备b, 张z飞f, 赵z子z龙l]

如果有一些非常用的汉字，生僻字等，建议使用一些jar包实现,比如pinyin4j

参考技术A 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

Java实现数组的中文排序

 1 package demo;
 2 
 3 import java.text.Collator;
 4 import java.util.ArrayList;
 5 import java.util.Arrays;
 6 import java.util.Comparator;
 7 
 8 public class Demo {
 9     
10     @SuppressWarnings("unchecked")
11     public static void main(String[] args) {
12 
13         sort();
14     }
15     
16     //按照中文第一个字母升序排列的排序
17     public static void sort(){
18         Comparator<Object> com=Collator.getInstance(java.util.Locale.CHINA);  
19         String[] newArray={"中山","汕头","广州","安庆","阳江","南京","武汉","北京","安阳","北方"};  
20         Arrays.sort(newArray,com);  
21         for(String i:newArray){  
22             System.out.print(i+"  ");  
23         }  
24     }
25 
26 }
