ArrayList vs Vector & Stack in Java | Part 3 | Collection Interface in Java | Vikas Singh

In this video, Let's learn about the difference between ArrayList vs Vector & Stack In Java. LinkedList in Java is a data structure that is used to store a sequence of elements. It provides a linked list implementation of the List interface, which can be used to store any number of elements in a sequence. LinkedList uses a sequence of nodes that are connected together by references. Each node stores an element and a reference to the next node in the sequence. The first node in the sequence is called the head, and the last node is called the tail. ArrayList and Vector are both classes in Java that implement the List interface and provide dynamic arrays. They have similar functionalities, but there are some differences between them: ArrayList: Is not synchronized, meaning it is not thread-safe (multiple threads can access and modify the ArrayList simultaneously) Its methods are not synchronized Provides slightly better performance than Vector due to lack of synchronization overhead Introduced in Java 1.2 Vector: Is synchronized, meaning it is thread-safe (only one thread can access and modify the Vector at a time) Its methods are synchronized Provides lower performance than ArrayList due to synchronization overhead Introduced in Java 1.0 Stack: Is a subclass of Vector, which means it is thread-safe and its methods are synchronized Provides methods for “pushing” and “popping” elements onto and off of the top of the stack, respectively Provides methods for peeking at the top element of the stack without removing it Introduced in Java 1.0 In summary, if you need thread-safe operations, then you should use Vector or Stack. If thread safety is not required, then ArrayList provides better performance in most cases.
