Java to achieve Chinese characters in accordance with pinyin sorting of sample code

Recently, we need to sort the characters by pinyin

public static void main(String[] args) {  

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

  String[] arr = { " Zhang SAN ", " Li si ", " Cathy ", " Liu six " ," Weeks  �  "," dai "," O wear "};  
  String[] arr1 = {" life "," Culture and education "," political "," natural "," religious ","  �   �  ","  �  things "," Economic and trade "};  

//The word is effective, dai a, dai li in the first word of the same feeling under pinyin than the second word, very smart oh & PI;
  Arrays.sort(arr, cmp);  
  for (int i = 0; i < arr.length; i++)  
//Dai a, dai li, li si, liu liu, wang wu, zhang SAN, zhou zhonghe.
      System.out.println(arr[i]);  

//The film is full of characters and effects, and the story is filmed to the end.
  Arrays.sort(arr1, cmp);  
  for (int i = 0; i < arr1.length; i++)  
      //Lessons: economy and trade, life, culture and education, politics, nature, religion, practices and practices;
      System.out.println(arr1[i]);  
}

Chinese characters are sorted by pinyin. Using the Comparator interface of util package, compare method can be used. Here are some examples:

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;//Salary  
     private Integer age;//Years  �   

    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 " Name: " + this.name + "t Salary: " + this.salary + "t  �  : " + this.age;  
    }  
}
 
   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;  
      }    
  }

 
   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 method:

public static void main(String[] args) {  

       List<Person> list = new ArrayList<Person>();  
       list.add(new Person("  �  the ",3400,25));  
       list.add(new Person(" The king  �  ",10000,27));  
       list.add(new Person(" Ang lee ",9000,30));  
       list.add(new Person("  �  tiger ",2500,22));  
       list.add(new Person(" Ender  �  ",3500,21));  
       Person[] personAry = new Person[list.size()];    
       personAry = list.toArray(new Person[list.size()]);  

     
      System.out.println("---  Before ordering  ------------------------------------");  
      for(Person p : personAry) {  
          System.out.println(p);  
      }  
      Arrays.sort(personAry,new SalaryComparator());  
      System.out.println("---  Sort by salary  ------------------------------------");  
      for(Person p : personAry) {  
          System.out.println(p);  
      }  

      Arrays.sort(personAry,new AgeComparator());  
      System.out.println("---  Sorted by year  ------------------------------------");  
      for(Person p : personAry) {  
          System.out.println(p);  
      }  

   }  
}

Here are the results:

-- before sorting ----
Salary: 3400 years
Salary: 10000 year
Name: ang lee salary: 9000 year
Salary: 2500 years
Salary: 3500 years

-- sorted by salary --
Salary: 2500 years
Salary: 3400 years
Salary: 3500 years
Name: ang lee salary: 9000 year
Salary: 10000 year

-- sorted by year ----
Salary: 3500 years
Salary: 2500 years
Salary: 3400 years
Salary: 10000 year
Name: ang lee salary: 9000 year
