An array is a linear data structure that is used to store a group of elements with similar datatypes. It stores data in a sequential manner. Once we create an array we can't change its size i.e. it can store a fixed number of elements. The array comes with a vast application and use case. Also, we can perform numerous operations on arrays. This article will help you to understand the basics of arrays and also, we will make java programs to perform right and left rotation operations on arrays. Java Program for Array Rotation First, let's understand the term ... Read More
In Java, multiplyExact() is an in-built static method of the Math class that accepts two arguments and returns their product as a result. This method can accept values of either integer or long type. One important point to note is that it may throw an exception if the produced result overflows the size of integer. After knowing the functionality of multiplyExact() in Java, one question that may pop into one's mind is that we can also use '*' operator to multiply two operands then why do we need multiplyExact() method. We are going to answer this question and also, explore ... Read More
In Python, a substring is a sequence of characters that appears within a larger string. For example, in the string "Hello, world!", the substring "world" appears within the larger string. A substring can be a single character, or it can be a longer sequence of characters. Substrings are useful when you need to extract or manipulate specific parts of a string. You can also check if a substring is contained within a larger string using Python's string methods. Python provides a built-in method to check if a string contains a substring. The method is called ‘in’ and it returns a ... Read More
In Java, we use inheritance to allow the creation of a hierarchical classification of classes and objects. As the name suggests, inheritance is the ability of a class to inherit members of another class. The class whose properties are inherited is called a superclass whereas the class that inherits a superclass is called a subclass. We use the extends keyword to inherit the class. There are several types of inheritance in Java such as single and multilevel. In this article, we will specifically explore the multiple inheritance. Multiple Inheritance in Java In the terminology of object-oriented programming, multiple inheritance is ... Read More
IntUnaryOperator Interface, a functional interface of Java that performs an operation on a single integer-valued operand and also returns an integer value as a result. Since it is a functional interface, we can use it as an assignment target for the lambda expressions or method references. Here, the functional interface means an interface that contains only a single abstract method and exhibits single functionality. Some examples of functional interfaces are Predicate, Runnable, and Comparable interfaces. The IntUnaryOperator interface is defined in the 'java.util.function' package. In this article, we are going to explore the IntUnaryOperator Interface and its built-in methods with ... Read More
You can perform some math operations on Python strings technically, but it may not work the way you expect it to. Here are a few examples: Concatenating Strings with + Example In this example, we concatenate two strings by using the + operator. This works because the + operator is overloaded in Python to work with strings as well as numbers. When we use the + operator with strings, it concatenates them together to form a single string. string1 = "Lorem " string2 = "Ipsum" result = string1 + string2 print(result) Output Lorem Ipsum Multiplying Strings with * ...

JSON (JavaScript Object Notation) has become popular and offers a lightweight and clean−to−read layout for replacing information between a server and a web application. With the assistance of jQuery, an effective JavaScript library, you could easily fetch statistics from a JSON document and display it on an HTML desk. To run the code nearby, a web server is required. Alternatively, a code editor with a live server plugin can be employed. Syntax $.getJSON() AJAX requests can be utilized to retrieve JSON data from files through this function. The function takes two arguments: URL: The primary argument is the URL ... Read More
Animated websites give users an enjoyable experience. An animated element, such as a link or button, may change colour, expand or shrink, rotate, or any combination of those actions when a website visitor hovers over it. This serves as visual confirmation that their interactions are effective in addition to being eye candy. Vue.js is a popular javascript framework for building interactive and visually appealing UI elements that can greatly enhance the user experience of your website or application. It provides a declarative and component−based programming approach that enables you to effectively create user interfaces, whether they are straightforward or intricate. ... Read More
Bootstrap is a popular open−source framework for building responsive and mobile−first websites. By offering a selection of pre−made design elements and layout components, this framework makes it simple for developers to produce standardised and expert−looking web pages. Forms, buttons, navigation, and typography are a few of these. To achieve expandable accordion, we will use hash property of URL interface often called USVString which contains ‘#’ followed by the identifier URL. Syntax .... The must be the directed url followed ... Read More
The process of creating web pages involves incorporating various special characters into HTML structures that have distinctive meanings. Nevertheless, some instances require designers to display symbols with speciality without browsers interpreting them as such; this is where escape characters come in handy. By using these codes correctly in an HTML block, designers can ensure proper rendering of all intended symbols on their web pages. Basic Escape Characters in HTML The escape character must be employed to escape characters within an HTML block. The escape character is denoted by the "&it" symbol, followed by a character code, and ends with another ... Read More
