Java – how to sort the list by string value (Persian letter)?

Invalid Sign

This is my code:

 public class Student {
    private String name;
    private int number;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getNumber() {
        return number;
    }

    public void setNumber(int number) {
        this.number = number;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", number=" + number +
                '}';
    }

}

Public class main{

    public static void main(String[] args) {

            List<Student> studentList = new ArrayList<Student>();

            Student temp1 = new Student();
            temp1.setName("ی");
            temp1.setNumber(5);

            Student temp2 = new Student();
            temp2.setName("م");
            temp2.setNumber(4);

            Student temp3 = new Student();
            temp3.setName("ک");
            temp3.setNumber(3);

            studentList.add(temp1);
            studentList.add(temp2);
            studentList.add(temp3);

            // before sort
            System.out.println("before sort");
            for(Student student : studentList){
                    System.out.println("Student name: " + student.getName());
            }

            Locale locale = new Locale("fa");

            System.out.println("--------------------");
            System.out.println("Language: " + locale.getDisplayLanguage());
            System.out.println("--------------------");

            if (studentList.size() > 0) {
                    Collections.sort(studentList, new Comparator<Student>() {
                            @Override
                            public int compare(final Student object1, final Student object2) {
                                    return Collator.getInstance(locale).compare(object1.getName(), object2.getName());
                            }
                    } );
            }

            // after sort
            System.out.println("after sort");
            for(Student student : studentList){
                    System.out.println("Student name: " + student.getName());
            }

    }

}

You can use the organizer to see:

Or create your own comparator. Here's the document

Object Ordering

The reason for sorting these strings is that the strings are sorted using the utf-16 char table. Therefore, in utf-16, these characters are:

> م Arabic letter (U 0645) > Arabic letter keheh (U 06a9) > Photo Arabic letter Farsi Yeh (U 06cc)
