This provides the architecture to store and manipulate a group of objects. In looking further to find how Java implements the structuring of data, I came across the Java Collection framework. This contains classes and interfaces which implement all these data structures, are ready to be used and make work easy for the coder. Java came up with a solution that provided an API in the java.util package. A tree data structure can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the Children), with the constraint that no reference is duplicated or points to the root.Įarlier, all these data structures were written in C or C++ and had to be created every time in order to store data. TreeĪ tree consists of a set of elements (nodes) which can be linked to other elements, sometimes hierarchically and sometimes not. The first element added to the queue will be the first one to be removed.

It is similar to a queue of people at a movie ticket counter. This is a FIFO (First In First Out) data structure. Push and Pop are the two main operations on the stack.

It can be implemented both through arrays and Linked List. It is like a pile of plates – the one put in last is removed first. This is a data structure that implements the LIFO (Last In First Out) paradigm. This structure allows for efficient insertion or removal of elements from any position in the sequence. Under the simplest form, each node is composed of data and a pointer to the next node. This data structure consists of a group of nodes, which together represent a sequence. This is a data structure that can store a fixed-size sequential collection of elements of the same type. Figure 1: Different data structuresĭata can be structured in many ways but the commonly used practices are given below: Arrays Searching a particular book from millions of books on Amazon or sorting through the endless choice of mobile phones on the basis of price are all done with low cost and low complexity algorithms, which work on structured data. In computer science, a data structure is a particular way of organising data in a computer so that it can be used efficiently. It is hard to process the raw data so the need for structured data arises, which is when data structures become handy. Data in its raw form is like a chunk of ore from which the diamond is yet to be extracted.
