Vector in Java. By Chaitanya Singh | Filed Under: Java Collections. Vector implements List Interface. Like ArrayList it also maintains insertion order but it is rarely used in non-thread environment as it is synchronized and due to which it gives poor performance in …

This Tutorial Explains all about Vector Data Structure in Java With Examples. You will learn to Create, Initial, Sort & Use A Java Vector in your Programs: A vector can be defined as a dynamic array that can grow or shrink on its own i.e. vector will grow when more elements are added to it and will shrink when elements are removed from it. This course covers the basics of C++ and in-depth explanations to all C++ STL containers, iterators etc along with video explanations of some problems based on the STL containers.

Vector object= new vector(int initialcapacity, capacityIncrement) Example: Vector vec= new Vector(4, 6) Here we have provided two arguments. The initial capacity is 4 and capacityIncrement is 6. It means upon insertion of 5th element the size would be 10 (4+6) and on 11th insertion it would be 16(10+6). Complete Example of Vector in Java:
