We can use a vector constructor for converting ArrayList to vector. We can read ArrayList elements one by one and add them in vector. Approach 1: (Using Vector Constructor) Create an ArrayList. Add elements in ArrayList. Create a vector and pass the ArrayList in Vetor Constructor. Since Vector class and ArrayList class both are part of Java Collections, ie Collection framework, so both of these classes can use methods available to the Collection framework.
* * This class is implemented to be immutable: once the client program Vectors are growable arrays that need to be initialized before it is used. Vector is a Java class and to use it, import the java.util package. The size is to be mentioned in arrays before being used, and once set, it cannot be changed, unlike Arrays. Therefore, Vectors implement a dynamic array.
a 11 (vector A has 55 ,11} 3. d (prints the size of the vector A ie. 2 ) Find Complete Code at GeeksforGeeks Article: https://www.geeksforgeeks.org/beginning-java-programming-with-hello-world-example/Practice Problem Online Judge: As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, Vector is synchronized.
Vector Constructors Basic Vector Operations. How to read all elements in vector by using iterator? How to read all elements in vector by using Enumeration? How to copy or clone a vector? How to add all elements of a list to vector? How to delete all elements from my vector?
Java’s Remote Method Invocation mechanism does just that. 2020-11-02

Methods: Using ArrayList.contains() Method; Using Vector.retainAll() method. Approach 1: Store the elements in the First collection and in the second collection (Array List). 2021-03-23 · Java is Object Oriented. However it is not considered as pure object oriented as it provides support for primitive data types (like int, char, etc) The Java codes are first compiled into byte code (machine independent code). Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture.
It provides random access of elements. It is good for large collection of elements. It extends an abstract class AbstractSeq and IndexedSeq trait.

Vector is a class that implements the List interface. It is a type of dynamic array that means the size of a vector can be grown or shrink during the execution of the program.
