Describing functions of arrays and Array lists
Array functions are used for sorting and searching elements in an array. It stores a sequence of values of a specified data type. Rather, it could be a double, int, string, etc. Arrays contain a set of values that the programmer assigns. Its elements are positioned by indices. And once the programmer declares a collection of elements, the length of it cannot be changed.
An ArrayList in Java is a sequence of values whose size you can change. ArrayList offers two concluding advantages that arrays do not.
- Array lists can increase and decrease if needed.
- The ArrayList class implements methods for basic tasks. For example, it can insert and remove elements.
