Thread: lookup method in a sorted linked list

Okay this should be the final post about this God forbidden topic.So i need to implement this following method.

 
public Person lookup(String name) {
		if(head == null) {
			return null;
		}
		if(head.person.name.compareTo(name) == 0) {
			head = head.next;
			return person;
		}
 
		Node current = head;
		Node prev = head;
		while(current != null) {
			if(current.person.name.compareTo(name) == 0) {
				prev.next = current.next;
				return person;
			}
			prev = current;
			current = current.next;
		}
		return null;
	}

Now the idea behind this is to go through the list checking for the parameter name and if we find a match return the person with that name.I think I did the "travesing" or going through the list part corectly, but the issue is the return value.When nothing is found null; makes sence.But if we find the person we need to return it. The return person here doesn't work I get this error:
PhoneBookList.java:92: error: cannot find symbol
return person;
^
symbol: variable person
location: class PhoneBookList
PhoneBookList.java:100: error: cannot find symbol
return person;
^
symbol: variable person
location: class PhoneBookList
2 errors

Any help? Thanks


EDIT: Okay I've figured it out actually,

 
public Person lookup(String name) {
 
        if (head == null) { 
            return null;
        }
 
        Node current = head;  
        while (current != null) {
            if (current.person.name.compareTo(name)==0) { 
                return current.person;
            }
            current = current.next; 
        }
        return null;
    }

Should work
