Thread Safety of Vector as Queue (Putting / Getting)

Question

i have a thread that is working on clearing a queue (a Vector).
however, new items are being added to the queue intermittently.
how should i do this properly?
is the process below sufficient?
Vectors are syncronized arent they?
So using the methods below would it be safe if the Vector is
having something removed as something is being added?
public class QueueHandler extends Thread{
public QueueHandler(){}
public void run(){
while(true){
// if Queue.size() > 0 --> Handle Queue items
// for(1 to size){ item = Queue.get(i); process(item)
public void processItem(item){
//do something
// Queue.remove(item);
public void addToQueue(item){
Queue.add(item);
Vector Queue;
}

import java.util.concurrent.*;
public class QueueHandler extends Thread {
  public void run() {
    while(true) {
      processItem(queue.take());
  public void processItem(Object item) {
    //do something
  public void addToQueue(Object item) {
    queue.put(item);
  private BlockingQueue queue = new BlockingLinkedQueue();
}
