Java LinkedList sort() metodi

❮ LinkedList metodlari

import java.util.LinkedList;

public class Main {
  public static void main(String[] args) {
    LinkedList<String> cars = new LinkedList<String>();
    cars.add("Volvo");
    cars.add("BMW");
    cars.add("Ford");
    cars.add("Mazda");
    cars.sort(null);
    System.out.println(cars);
  }
}

Ta’rif va qo‘llanilishi

sort() metodi ro‘yxatdagi elementlarni saralaydi. Elementlarni juftma-juft taqqoslash uchun Comparator obyektidan foydalanish mumkin. Komparatorni Java tilidagi Comparator interfeysining compare() metodiga mos keladigan lambda ifodasi orqali belgilash mumkin.

Agar metodga null uzatilsa, elementlar ma’lumot tipiga qarab tabiiy tartibda saralanadi (masalan, stringlar alifbo bo‘yicha, sonlar qiymati bo‘yicha). Primitiv bo‘lmagan tiplar komparatorsiz saralanishi uchun Java tilidagi Comparable interfeysini amalga oshirishi (implement qilishi) kerak.
