A linked list is a finite sequence of nodes each of which contains a pointer field pointing to the next node. In many languages, a pointer to the first node must be supplied. In a simply linked list, the pointer in the last node points to nil. In an empty list, the pointer in the first node points to nil. In the current Java implementation,the types of elements which can be added to the list are those of type Object or one of it's subclasses. In Java, the Object class is the superclass from which all other classes are derived. This makes it possible to add elements of almost any type to a list, except the built in primitive data types (int, long, char, boolean, long,double). To add elements of these types, it is necessary to convert them from primitive types to classes, which Java supports quite easily. In order to convert the primitive types to classes method overloading is used. In Java, there can be multiple definitions of a method with the same name but different parameters. The Java interpreter will know the right method to call while running based on the parameters passed by the caller. This process, method overloading, is employed to convert the different data types listed above. The primary advantage of a linked list over an array is that a linked list can grow and shrink as needed. In Java, the creation of new objects for inclusion in the list is dynamic and can easily be accomplished without much overhead. Other languages,however, pay some overhead for the pointers they utilize. Another advantage of a linked list is the flexibility derived from rearranging elements efficiently, though this flexibility is gained at the expense of quick access to any object in the list.
Which of the following data structures can be randomly accessed giving loc?A. linked list implemented using arrayB. singly linked listC. double linked listD. both single and double linked listThe answer is A.
Physical data structures are how data is organized on a hardware storage device, and therefore how they appear to the computer. Logical or virtual data structures are software-based objects, and how the user or program sees it. Although many file systems use a type of linked list format for storing information, a linked list is used for both hardware and software purposes, and therefore it cannot fall under either the physical or virtual data structure classification.
Linear list for example is array, linked list, stack, ... It is called linear because all elements in those data structures are in linear sequence. We have first and the last elements in the list. If there is N elements in list, we know that all elements are in such sequence na, na+1. Non-linear structures would be trees and graphs.
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
A linked list is used in computer science to store data as a series of related nodes. Linked lists are used as the basis for abstract data types when programming. The chief advantage of a linked list is that data can be added or removed from the list without having to reorganize the whole list. A drawback to linked lists can be that it is difficult to sort, organize, or recall specific information from the list.

A heterogeneous linked list is a linked list where each node can store different types of data. This is different from a homogeneous linked list where all nodes store the same type of data. Heterogeneous linked lists can be useful for scenarios where you need to store multiple types of data in a single list.
Heterogeneous Linked List is a linked list data-structure that contains or is capable of storing data for different datatypes.void pointer is basically used in these types of linked list as we are not sure of which type of data needs to be stored

I tried my best to explain all Linked List. For Single Linked List http://www.fansonnote.com/2012/02/single-linked-list/ For Double Linked List http://www.fansonnote.com/2012/02/double-linked-list/ For Multi Linked List http://www.fansonnote.com/2012/02/multi-linked-list/ Hope it will help. Thanks.
Yes.
In C programming, a double linked-list refers to a linked data structure that contains a set of links that have been linked sequentially.
Yes definitely, a linked list can accept duplicate data. As the data of each node does not have any concern with data of other node. The node differs from each other in their addresses. Until user does not make the linked list to accept unique data, the linked list can accept duplicates. if unsorted (e.g. representig a queue): yes if sorted (e.g. representing a set): should be decided design-time
It depends on what you intend to do with the data. The assumption is the data is dynamic, the number of elements are not known in advance. Binary trees are best if you want to sort the data as it is entered. Linked lists are best if you simply want a list of sequential data, or need to implement a stack or a queue.
