java中漢字按拼音排序

文章分类:Java编程

 

最近項目中需要對繁體字按拼音進行排序

 

 public   static   void  main(String[] args) {

   Comparator cmp = Collator.getInstance(java.util.Locale.CHINA);

   String[] arr = { "张三" ,  "李四" ,  "王五" ,  "刘六"  , "周濤" , "戴笠" , "戴阿" };
   String[] arr1 = {"生活" , "文教" , "政治" , "自然" , "宗教" , "經貿" , "軍事" , "经贸" };

 //對簡體字有效，戴阿、戴笠在第一個字相同的情況下按拼音比較第二個字，很智能哦
   Arrays.sort(arr, cmp);
   for  ( int  i =  0 ; i < arr.length; i++)
 //輸出：戴阿、戴笠、李四、刘六、王五、张三、周濤
       System.out.println(arr[i]);

 //對繁體字無效，繁體的“軍事”被拍到了最后
   Arrays.sort(arr1, cmp);
   for  ( int  i =  0 ; i < arr1.length; i++)
       //輸出：经贸、生活、文教、政治、自然、宗教、經貿、軍事
       System.out.println(arr1[i]);
 }

public static void main(String[] args) { 
       
  Comparator cmp = Collator.getInstance(java.util.Locale.CHINA);     

  String[] arr = { "张三", "李四", "王五", "刘六" ,"周濤","戴笠","戴阿"}; 
  String[] arr1 = {"生活","文教","政治","自然","宗教","經貿","軍事","经贸"}; 

//對簡體字有效，戴阿、戴笠在第一個字相同的情況下按拼音比較第二個字，很智能哦 
  Arrays.sort(arr, cmp); 
  for (int i = 0; i < arr.length; i++) 
//輸出：戴阿、戴笠、李四、刘六、王五、张三、周濤 
      System.out.println(arr[i]); 

//對繁體字無效，繁體的“軍事”被拍到了最后 
  Arrays.sort(arr1, cmp); 
  for (int i = 0; i < arr1.length; i++) 
      //輸出：经贸、生活、文教、政治、自然、宗教、經貿、軍事 
      System.out.println(arr1[i]); 
} 

 關于繁體字按拼音排序，可以利用util包下的Comparator接口，按自定義的規則實現compare方法即可。以下是個例子：

 package  zhouyrt;
 import  java.util.ArrayList;
 import  java.util.Arrays;
 import  java.util.Comparator;
 import  java.util.List;
 public   class  PinyinPaixu {
      static   class  Person {

      private  String name;
      private  Integer salary; //薪水
      private  Integer age; //年齡

     Person(String n, Integer s, Integer a) {
        this .name = n;
        this .salary = s;
        this .age = a;
     }

     public  String getName() {
        return  name;
     }
     public   void  setName(String name) {
       this .name = name;
     }
     public  Integer getSalary() {
       return  salary;
     }
     public   void  setSalary(Integer salary) {
       this .salary = salary;
     }
     public  Integer getAge() {
       return  age;
     }
     public   void  setAge(Integer age) {
       this .age = age;
     }

     public  String toString() {
       return   "姓名："  +  this .name +  "\t薪水："  +  this .salary +  "\t年齡："  +  this .age;
     }
 }

package zhouyrt; 
import java.util.ArrayList; 
import java.util.Arrays; 
import java.util.Comparator; 
import java.util.List; 
public class PinyinPaixu { 
     static class Person { 
   
     private String name; 
     private Integer salary;//薪水 
     private Integer age;//年齡 
   
    Person(String n, Integer s, Integer a) { 
       this.name = n; 
       this.salary = s; 
       this.age = a; 
    } 
   
    public String getName() { 
       return name; 
    } 
    public void setName(String name) { 
      this.name = name; 
    } 
    public Integer getSalary() { 
      return salary; 
    } 
    public void setSalary(Integer salary) { 
      this.salary = salary; 
    } 
    public Integer getAge() { 
      return age; 
    } 
    public void setAge(Integer age) { 
      this.age = age; 
    } 
   
    public String toString() { 
      return "姓名：" + this.name + "\t薪水：" + this.salary + "\t年齡：" + this.age; 
    } 
} 

 

 

 /*

    static   class  SalaryComparator  implements  Comparator {

main方法測試：

 public   static   void  main(String[] args) {

        List<Person> list = new  ArrayList<Person>();
        list.add(new  Person( "張洋" , 3400 , 25 ));
        list.add(new  Person( "王肅" , 10000 , 27 ));
        list.add(new  Person( "李安" , 9000 , 30 ));
        list.add(new  Person( "劉虎" , 2500 , 22 ));
        list.add(new  Person( "安德剛" , 3500 , 21 ));
        Person[] personAry = new  Person[list.size()];
        personAry = list.toArray(new  Person[list.size()]);


       System.out.println("--- 排序前 ------------------------------------" );
       for (Person p : personAry) {
           System.out.println(p);
       }
       Arrays.sort(personAry,new  SalaryComparator());
       System.out.println("--- 按薪水排序后 ------------------------------------" );
       for (Person p : personAry) {
           System.out.println(p);
       }

       Arrays.sort(personAry,new  AgeComparator());
       System.out.println("--- 按年齡排序后 ------------------------------------" );
       for (Person p : personAry) {
           System.out.println(p);
       }

    }
 }

public static void main(String[] args) { 
   
       List<Person> list = new ArrayList<Person>(); 
       list.add(new Person("張洋",3400,25)); 
       list.add(new Person("王肅",10000,27)); 
       list.add(new Person("李安",9000,30)); 
       list.add(new Person("劉虎",2500,22)); 
       list.add(new Person("安德剛",3500,21)); 
       Person[] personAry = new Person[list.size()];   
       personAry = list.toArray(new Person[list.size()]); 

   
      System.out.println("--- 排序前 ------------------------------------"); 
      for(Person p : personAry) { 
          System.out.println(p); 
      } 
      Arrays.sort(personAry,new SalaryComparator()); 
      System.out.println("--- 按薪水排序后 ------------------------------------"); 
      for(Person p : personAry) { 
          System.out.println(p); 
      } 
   
      Arrays.sort(personAry,new AgeComparator()); 
      System.out.println("--- 按年齡排序后 ------------------------------------"); 
      for(Person p : personAry) { 
          System.out.println(p); 
      } 
   
   } 
}
