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.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; 
    } 
}

main方法測試：

public
 
static
 
void
 main(String[] args) {

       List<Person> list = new
 ArrayList<Person>();
       list.add(new
 Person(
"張洋"

25

       list.add(new

       list.add(new

       list.add(new

       Person[] personAry = new

       personAry = list.toArray(new

      System.out.println("--- 排序前 ------------------------------------"

      }

      Arrays.sort(personAry,new

   }
}

public static void main(String[] args) {

      }

      System.out.println("--- 按薪水排序后 ------------------------------------"); 
      for(Person p : personAry) {
