We must define an array before we can use it to store information.

The indexing of the variable in an array starts from 0.

The common data type of array elements is known as the base type of the array.

Arrays can have data items of simple and similar types such as int or float, or even user-defined datatypes like structures and objects.

The first address of the array belongs to the first element and the last address to the last element of the array. Arrays consist of contiguous memory locations. There are some common types of data structure in Java they are as follows –Īn Array, which is the simplest data structure, is a collection of elements of the same type that are referenced by a common name. The client program uses the data structure with the help of the interface only, without having knowledge of the implementation details.

Abstraction: In Java, the ADT (Abstract Data Types) is used to specify a data structure.We can compile the implementation of these data structures into libraries and the clients can use these libraries in many ways. Reusability: Data structures provide reusability of data, that is after implementing a particular data structure once, we can use it many times at any other place.Efficiency: Data Structures are used to increase the efficiency and performance of an application by organizing the data in such a manner that it requires less space with higher processing speed.

Data structure stores and manages the data in such a way that the required data can be searched instantly. In order to solve the above problems, we use data structures.

Multiple requests at the same time: Suppose, millions of users are simultaneously searching the data on a web server, then there is a chance of server failure.

This results in slowing down the search process. If your application needs to search for a particular item, it needs to traverse 200 items in every search.

Searching data: Consider an inventory with a size of 200 items.

Processing Speed: As the data is increasing day by day, high-speed processing is required to handle this massive amount of data, but the processor may fail to deal with that much amount of data.

The need for Data Structures in JavaĪs the amount of data grows rapidly, applications get more complex, and there may arise the following problems:

We use Data Structures primarily in almost every field of Computer Science, which is Computer Graphics, Operating systems, Artificial Intelligence, Compiler Design, and many more.

A data structure is a unique way of storing or organizing the data in computer memory so that we can use it effectively. The term data structure refers to a data collection with well-defined operations and behavior or properties. Since data structure is a core to any programming language and choosing a particular data structure majorly affects both the performance and functionality of Java applications, therefore it’s worth an effort to learn different data structures available in Java. Sorting through the endless choice of mobile phones based on price or searching a particular book from millions of books on Flipkart, are all done with less complex and low-cost algorithms, which work on structured data.
