What is the limitation of array?

Arrays are used to store and manipulate collections of elements. Once declaring an array it is not possible to modify its size. An Array supports only elements of the identical “data type” and the same size.

What is array with example?

An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. … For example, a search engine may use an array to store Web pages found in a search performed by the user.

What is Array give the advantage and disadvantage?

It allows us to enter only fixed number of elements into it. We cannot alter the size of the array once array is declared. Hence if we need to insert more number of records than declared then it is not possible.

What is the difference between Array and array list?

An array is basic functionality provided by Java. ArrayList is part of collection framework in Java. Therefore array members are accessed using [], while ArrayList has a set of methods to access elements and modify them. Array is a fixed size data structure while ArrayList is not.

What is difference between array and linked list?

An array is the data structure that contains a collection of similar type data elements whereas the Linked list is considered as non-primitive data structure contains a collection of unordered linked elements known as nodes.
