• Vector is considered as a legacy code and avoided by the developers.
• Collection frameworks can compose everything a vector can do.
• Vector is opted during thread-safe operation, ensuring that only one thread is tendered while accessing the collection.
• Fore thread safe operation, synchronized ArrayList   is preferred.
