مساعدة في تصحيح كود

مثال:

("apple","cat","xray")

Then the call Replicate(list,3) should change list as shown below.

("apple","apple","apple","cat","cat","cat","xray","xray","xray")

الكود الاول:

public class SLLNode<E> {

E element;

SLLNode<E> next;

SLLNode(E elem,SLLNode<E> succ){

this.element=elem;

this.next=succ;

}

}

الكود الثاني:

public class SLL<E> {

SLLNode<E> first;

SLL(){

this.first=null;

}

public void printList(){

for(SLLNode<E> curr=this.first;curr!=null; curr=curr.next)

System.out .println(curr.element);

}

public void replicate(){

for (SLLNode<E> curr = first; curr != null; curr = curr.next) {

first=this.first;

first=this.first.next;

first=this.first.next.next;

first=this.first;

first=this.first.next;

first=this.first.next.next;

first=this.first;

first=this.first.next;

first=this.first.next.next;

System.out.print(curr.element);

}

}

}

الكود الثالث:

public class SLLTester{

private SLL sll = null;

public void createSLL()

{

this.sll = new SLL();

}

public void printList()

{

this.sll.addFirst("apple");

this.sll.addMiddle("cat");

this.sll.addLast("xray");

}

public void replicate()

{

this.sll("Apple");

sll.replicate();

this.sll("Cat");

sll.replicate();

this.sll("xray");

sll.repliacte();

}

public static void main(String[] args) {

SLLTester sllTester = new SLLTester();

sllTester.printList();

sllTester.replicate();

}

}
