Java에서 스레드로부터 안전한 컬렉션을 만드는 방법은 무엇입니까?

import java.util.Collection;
import java.util.Collections;
import java.util.Vector;
public class CollectionReadOnly {
   public static void main(String[] args) {
      //Instantiating an ArrayList object
      Vector<String> vector = new Vector<String>();
      vector.add("JavaFx");
      vector.add("Java");
      vector.add("WebGL");
      vector.add("OpenCV");
      System.out.println(vector);
      Collection<String> synchronizedVector = Collections.synchronizedCollection(vector);
      System.out.println("Synchronized "+synchronizedVector);
      synchronizedVector.add("CoffeeScript");
   }
}
