In Java, HashSet is a class which implements Set Interface. HashSet is a collection of unique elements which doesn’t store or allow us to store duplicate elements. In this section, we will be discussing about different approaches in java to find the first element and last element of a HashSet using Java programming Language. The HashSet class in java is implemented using a hash table. It uses hash code to retrieve data quickly from the table in HashSet, the order of elements is not preserved i.e., it doesn’t store the elements in the order in which we add elements ... Read More

IP Address, also known as the Internet Protocol Address is a unique identifier that is assigned to a device in a network to identify the devices in the network and establish connection between them. In this section, we will learn how to find the IP Address of a Windows and Linux Machine using Java Code. IP address can be represented in two formats. One format is IPv4 which is a 32 format containing decimals and dots. It has two parts, one part is network ID which identifies network and the other is host ID which identifies the device in ...

LinkedHashSet is a class provided by Java which Implements Set Interface. LinkedHashSet is implemented as a hash table with a linked list running through it, so it is more efficient that HashSet and also maintains orders. It is useful when you need a collection that maintains order and does not allow duplicates. In this section, we will discuss different approaches to get the elements from LinkedHashset by index. What is a LinkedHashSet? A LinkedHashSet is a collection which is a combination of HashSet collection and a LinkedList collection. A HashSet is an unordered collection and also doesn’t allow duplicates. ... Read More

Last Modification Date of a File refers to the last date on which the file data is edited. We have various functions in java to find the last modification date of a file. In this section, we will be discussing different approaches of implementing a java program to get the last modification date of a file. File is a collection of information which may contain data such as text information, images, audio, videos, program code. These can be accessed by any software applications to perform actions like read, write, update, delete etc. We will now look in to each function ... Read More

Python offers a wide range of data structures to efficiently organize and manipulate data. When it comes to handling sorted data, sorted containers play a crucial role. Sorted containers are data structures that maintain the elements in a sorted order, providing fast access, insertion, and deletion operations. They offer an effective solution for scenarios where maintaining a sorted order is essential. In this blog post, we will explore the world of Python sorted containers and understand their significance in various applications. We will delve into the different types of sorted containers, such as sorted lists, sorted sets, and sorted dicts, ... Read More

Data visualization plays a crucial role in understanding and communicating patterns, trends, and insights from data. Python, with its rich ecosystem of libraries, offers powerful tools for creating visually appealing and informative plots. Seaborn, a popular data visualization library built on top of Matplotlib, provides a high-level interface for creating beautiful statistical graphics. In this article, we will explore one of Seaborn's versatile plot types - the strip plot. Strip plots are useful for visualizing the distribution of a continuous variable against a categorical variable. They display individual data points along an axis, making it easy to observe patterns, clusters, ... Read More

Collections in Java is a framework which provides classes and interfaces to manipulate group of objects. Collections help in storing and manipulating different types of objects in java. Size of the collection tells us how many elements are present in that particular collection. Java provides various collection classes namely ArrayList, LinkedList, HashSet, and TreeSet, among others. In this section, we are going to write a java program to get the size of collection and verify the collection is empty or not. The different types of collections in Java are − List − List is an ordered collection of objects ... Read More
