ArrayList: ArrayList is used to store the elements dynamically. When a new element is added to the ArrayList, its length increases automatically. In Java, ArrayList is a type of collection framework and it implements an interface called List. Unlike Array, the mixture of objects of any type can be used in ArrayList. Syntax: ArrayList() objectName=new ArrayList(); Here, “ArrayList()” is the class name with no arguments. One can use “ArrayList(Collection C)” and “ArrayList(int)” from “util” package. “objectName” defines the name of the object of ArrayList.
