TreeMap is a class of Java Collection Framework that implements NavigableMap Interface. It stores the elements of the map in a tree structure and provides an efficient alternative to store the key-value pairs in sorted order. Note that while creating objects of TreeMap it is necessary to use either the Comparable Interface or Comparator Interface so that we can maintain the sorting order of its elements otherwise, we will encounter a java.lang.ClassCastException. In this article, we are going to explain how to use the Comparable and Comparator Interfaces to fix this ClassCastException in TreeMap. Fixing java.lang.ClassCastException in TreeMap ... Read More
The TreeSet is a generic class of Java Collection Framework that implements the SortedSet Interface. It stores the elements of the set in a tree structure. Furthermore, all the elements are stored in a sorted manner and they must be mutually comparable if we are attempting to add custom class objects otherwise we will encounter a java.lang.ClassCastException. Here, custom class objects mean user-defined objects that are created with the help of a constructor. To fix this ClassCastException in TreeSet we can use either the Comparator Interface or the Comparable Interface. Let's discuss them in detail. The general ... Read More
The TreeSet is a generic class of Java Collection Framework that implements the SortedSet Interface. It stores the elements of the set in a tree structure. Furthermore, all the elements are stored in a sorted manner and they must be mutually comparable if we are attempting to add custom class objects otherwise we will encounter a java.lang.ClassCastException. Here, custom class objects mean user-defined objects that are created with the help of a constructor. One way to fix this ClassCastException is by using a custom comparator. Let's discuss it in detail. The general syntax for TreeSet is as ... Read More
In the previous 10 years, mega web platforms were the most prominent enhancement of cultural change. With broad reception and close to boundless scale, enormous tech stages were sold as a public decent and development liberated from moral responsibilities regarding each buyer and business to profit from. The Dangerous Remedy In their urgency to safeguard their information and foundation, a few organizations have gone to a dangerous remedy: putting away information on their servers or building confidential mists. While this approach might appear consistent, it can build the gamble of cyber-attacks and information breaches. Constructing and keeping a confidential cloud ... Read More
LinkedHashMap is a generic class of Java Collection Framework that implements Map Interface. As the name suggests, it is a sub-class of the HashMap class and uses a doubly LinkedList to store the entries in insertion order. It maintains Key-Value pair of entries. The Key is an object that is used to fetch and receive value associated with it. Hence, we can use this key along with 'get()' method to get all the values from LinkedHashMap. The aim of this article is to explain different ways to print all values of the LinkedHashMap. Java Program to Get all ... Read More
Cloud computing is one of the most significant technological advances in the last decade. It has transformed data storage and access, program execution, and resource management. Cloud computing has become an essential component of current IT infrastructure, and its significance will only grow. We may anticipate some significant breakthroughs in cloud computing in 2023. This article will discuss the top 12 cloud computing projects in 2023. Hybrid Cloud Management Hybrid cloud management aims to make it easier for enterprises to manage their hybrid cloud deployments. This project will provide tools and technology to enable businesses to manage their on-premise and ... Read More
LinkedHashMap is a generic class of Java Collection Framework that implements Map Interface. As the name suggests, it is a sub-class of the HashMap class and uses a doubly LinkedList to store the entries in insertion order. However, LinkedHashMap does not do any kind of indexing to store the entries, therefore, it is quite a challenge to get specified values from LinkedHashMap with the help of an index. The aim of this article is to explain how to find a value from LinkedHashMap using the index. Java Program to Get a Value from LinkedHashMap by Index Before jumping ... Read More
LinkedHashSet is a class of Java Collection Framework that implements the Set interface and extends the HashSet class. It is a linked list type of collection class. It stores and returns the objects in the order in which they were inserted. Finding maximum and minimum elements from a LinkedHashSet collection is one of the common tasks that are frequently asked in exams and even in job interviews. In this article, we are going to explore a few approaches for performing the given task. Program to get Minimum and Maximum elements from LinkedHashSet To find the maximum ... Read More
In Java, Map is an object that stores its element in key-value pairs. The Key is an object that is used to fetch and receive value associated with it. The keys must be unique, but the values associated with them may be duplicated depending on the type of Map class we use. There are several approaches to find an entry with the largest key in Java map and these approaches also depend on the type of Map class we are working with. In this article, we will discuss how to find the entry with largest key in HashMap ... Read More
In this article, we'll make two channels in Go: one for even numbers and another for odd numbers. We are going to send the even numbers to the even channel and the odd numbers to the odd channel.Here we are going to use two different methods: using creating even and odd channels and Sending Even and Odd Numbers to Channels along with examples to elaborate the concept. Syntax close(evenChan) This is a built in function call used to close a channel. This make sure that no more value will be sent on the channel, and a send operation on ... Read More
