java中实现汉字按照拼音排序(示例代码)

来源: 互联网发布时间：2014-10-30

本文导语: 最近項目中需要對繁體字按拼音進行排序代码如下: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 = {...

最近項目中需要對繁體字按拼音進行排序

代码如下:

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：

代码如下:

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;
    }
}

/*
* 按薪水排序，從低到高
*/
   static class SalaryComparator implements Comparator {
      public int compare(Object o1, Object o2) {

         Integer salary1 = ((Person)o1).salary;
         Integer salary2 = ((Person)o2).salary;
         if(salary1 - salary2 > 0)
           return 1;
        if(salary1 - salary2 < 0)
           return -1;
        else
           return 0;
      }
}

/*
* 按年齡排序，從低到高
*/
   static class AgeComparator implements Comparator {
       public int compare(Object o1, Object o2) {

          Integer age1 = ((Person)o1).age;
          Integer age2 = ((Person)o2).age;
          if(age1 - age2 > 0)
               return 1;
          if(age1 - age2 < 0)
               return -1;
          else
                return 0;
       }
   }

main方法測試：

代码如下:

public static void main(String[] args) {  

       List list = new ArrayList();  
       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);  
      }  

   }  
}
