LinkList (Java)

Java Linked List class uses doubly linked list to store the elements.

The important points about Java Linked List are:
  • Java Linked List class can contain duplicate elements.
  • Java Linked List class maintains insertion order.
  • Java Linked List class is non synchronized.
  • In Java Linked List class, manipulation is fast because no shifting needs to be occurred.
  • Java Linked List class can be used as list, stack or queue.                                                            Syntax:-                                                                                                                                                      Link List<string>name=new Linked List<string>();                                                                                  {
………………………..    (Description)                                                                                                                                        }                                                                                                                                                                                Example:-
Public Class MyClass
{
pulic static void main(string[] args)
{
LinkList<string>name=new LinkedList<string>();
name.add(“ABC”);      //Add a name in LinkList
name.add(“PQR”);     //Add a name in LinkList
name.add(“XYZ”);     //Add a name in LinkList
for(string:name)
System.out.println(x);
name.addfirst(“Jack”);     //Add First name in LinkList.
name.addlast(“Zack”);     //Add Last name in LinkList.
name.removelast();            //Remove  First name in LinkList.
name.removefirst();         // Remove Last name in LinkList.
name.clear();                    //Delete all the data in LinkList.
System.out.println(name.size());
name.add(index,”element”);      //This is a syntax for add a variable of particular position in LinkList.
name.add(2,”Index”);
name.remove(2);     // Remove a variable of particular position in LinkList
name.set(1,”a”);  //Change a name as particular index.
}
}
