Java nima Java dasturlash tili

Javada LinkedList classi

• Javada LinkedList doubly linked list dan foydalanib elementlarni yig’adi. U AbstractList clasidan meros(extends) oladi va List va Deque interface lardan implement oladi ArrayListdan farqlaridan ham biri Deque dan implement olishidur.

• LinkedList da bir xil elementlar saqalsh mumkun

• LinkedList da malumotlar krirtilish ketma ketligida saqlanadi

• LinkedList class sinxron emas

• LinkedList classda boshqarish jarayonlari tez sodir bo’ladi chunkiy LinkedList da elementlarni ko’chirib o’tkazilmaydi

• LinkedList list, steck yokiy queue lardan foydalanishi mumkun

LinkedList da ham ma’lumotlar bilan ishlash ArrayList bilan deyarli birxil amalga oshiriladi.

1. 
   import java.util.*;
   
2. 
   public class TestCollection7{
   
3. 
    public static void main(String args[]){
   
4. 
   
   
5. 
   LinkedList al=new LinkedList();
   
6. 
   al.add("Zafar");
   
7. 
   al.add("Aziz");
   
8. 
   al.add("Jalol");
   
9. 
   al.add("Zafar");
   
10. 
    
    
11. 
    Iterator itr=al.iterator();
    
12. 
    while(itr.hasNext()){
    
13. 
    System.out.println(itr.next());
    
14. 
    }
    
15. 
     }
    
16. 
    }
    

ArrayList saqalagan ma’lumotlarni LinkedList ham saqlashi mumkun

LinkedListda gi ma’lumotlarni ArrayListga qo’shib qo’yishga misol

import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

public class ConvertExample {

public static void main(String[] args) {
LinkedList linkedlist = new LinkedList();
linkedlist.add("Zafar");
linkedlist.add("Aziz");
linkedlist.add("Jalol");
linkedlist.add("Fayzullo");

List list = new ArrayList(linkedlist);

for (String str : list){

System.out.println(str);
}
}
}
