Today, I have shared completely usage of ArrayList in Java. The ArrayList class is an implementation of the List interface in the Collections Framework. The ArrayList class creates a variable-length array of object references. The ArrayList class includes all elements, including null. In addition to implementing the methods of the List interface, this class provides methods to change the size of the array that is secondhand inside to store the list. Each ArrayList instance includes a capacity that represents the size of the array. A capacity stores the elements in the list and grows automatically as elements are added to an ArrayList. The ArrayList class is best right for chance access deprived of implanting or confiscating elements from any place other than the end.
Basically, ArrayList is a Class which is used to store multiple values such as Numerical and Alphabetically, ArrayList is a class of Collections, and there are many different classes and Interfaces available in Collections. If you have used Array and you can store only type values doesn’t store several types. But ArrayList provided with use Store Multiple Values in Single ArrayList.
