isEmpty() – Return true if the list is empty, otherwise return false.
size() – Return the number of elements in the list.
replace() – Replace an element at any position by another element.
removeAt() – Remove the element at a specified location from a non-empty list.
remove() – Remove the first occurrence of any element from a non-empty list.
insert() – Insert an element at any position of the list.
get() – Return an element from the list at any given position.
The data node contains the pointer to a data structure and a self-referential pointer which points to the next node in the list.
The data is generally stored in key sequence in a list which has a head structure consisting of count, pointers and address of compare function needed to compare the data in the list.
Now we’ll define three ADTs namely List ADT, Stack ADT, Queue ADT. Think of ADT as a black box which hides the inner structure and design of the data type. So a user only needs to know what a data type can do, but not how it will be implemented. The user of data type does not need to know how that data type is implemented, for example, we have been using Primitive values like int, float, char data types only with the knowledge that these data type can operate and be performed on without any idea of how they are implemented. The process of providing only the essentials and hiding the details is known as abstraction. It is called “abstract” because it gives an implementation-independent view. It does not specify how data will be organized in memory and what algorithms will be used for implementing the operations. The definition of ADT only mentions what operations are to be performed but not how these operations will be implemented.
Implementing a Linked List in Java using ClassĪbstract Data type (ADT) is a type (or class) for objects whose behavior is defined by a set of values and a set of operations.
