Inheritance: Inheritance is a fundamental concept in object-oriented programming (OOP) that allows classes to inherit properties and behaviors from other classes. It is a mechanism for creating new classes based on existing classes, promoting code reuse and establishing hierarchical relationships between classes. Inheritance is based on the concept of a "parent-child" or "superclass-subclass" relationship. The class from which another class inherits is called the superclass or base class, while the class that inherits from the superclass is called the subclass or derived class. The subclass inherits all the properties (variables) and methods (functions) of its superclass and can also ... Read More
TypeScript, a superset of JavaScript, offers static typing capabilities that enhance code quality and catch errors during compilation. To fully leverage TypeScript's static typing features, it's crucial to have type definition files (.d.ts) for external JavaScript libraries and modules used in projects. These type definition files describe the types and interfaces exposed by the external entities, enabling the TypeScript compiler to understand their shape and behaviour. In this article, we'll explore the step-by-step process of creating custom TypeScript type definition files, empowering developers to benefit from static typing in their projects. Prerequisites Type definition files (.d.ts) serve as an interface ... Read More
TypeScript, an extension of JavaScript, introduces modules as a means to structure and organize code effectively. Modules play a vital role in developing scalable and maintainable applications by enabling code encapsulation and reusability. TypeScript supports two types of modules: internal (namespaces) and external (ES modules). In this article, we will delve into the differences between internal and external modules in TypeScript, exploring their characteristics and impact on code organization and sharing within a project. Internal Modules Internal modules, also known as namespaces, serve as logical containers within a single file to group related code elements together. They offer benefits such ... Read More
Many Android applications have the zoomable scrolling feature, which enables users to pinch or stretch their fingers on the screen to zoom in and out of material like photographs or maps. Using a Zoom Scroll View, a custom view that expands the Android ScrollView and offers built-in support for zooming and scrolling, is one popular method for implementing zoomable scrolling in Android. We shall examine how to implement Zoom Scroll View on Android in this technical writing. In this tutorial, we'll go through the fundamental ideas and procedures needed to develop zoomable scrolling in your Android application using a Zoom ... Read More
We all are well aware are that now-a-days various coding platforms include competitive codings, for example GeeksforGeeks, CodeChef, Codeforces, atCoder, SPOJ, HackerRank, HackerEarth, and many more where they supposed to code out by themselves by either attaching local editor file such as a sublime editor or by directly writing on their respective editors. So how are these test cases getting accessed or in an easy way we can say that our code is getting compiled and run? On these programming platforms for competitive programming online judges act as the backbone for code compilation and run. Online Judge To judge ... Read More
PHP: PHP (Hypertext Preprocessor) is a widely-used open-source server-side scripting language that is specifically designed for web development. It was originally created by Rasmus Lerdorf in 1994 and has since evolved into a powerful language used by millions of developers worldwide. PHP is primarily used to develop dynamic web pages and web applications. It allows developers to embed PHP code within HTML, making it easy to mix server-side logic with the presentation layer. PHP scripts are executed on the server, and the resulting HTML is sent to the client's browser. There are several ways to measure script execution ... Read More

In PHP, null is a special value that represents the absence of a value or the lack of a specific data type. It is a built-in constant in PHP and is used to indicate the intentional absence of any object or value. Here are some key points about null in PHP: null is a data type: In PHP, null is a unique data type that stands on its own. It is distinct from other data types like strings, integers, booleans, arrays, etc. Absence of a value: When a ... Read More
