Vue is a JavaScript framework that allows developers to create web applications. It is mainly used to build single-page web applications. There are lots of benefits to using the vue to create web applications, such as easy structure, lightweight, component-based architecture, etc. Before we start with the tutorial, let’s learn about the reporting app and composition API. The reporting app is a single or multiple-page web application that displays useful data in a proper format, such as table format. It is used to show the reports of the data in a particular format. The composition API allows developers to code ... Read More
The fps word is generally associated with videos and games where we require to use animations. The fps is an abbreviation of frames per second, and it means how many times it’s rerendering the current screen. For example, a video is a continuous row of images. It means it shows images in very short intervals so that users can’t know it's showing images individually. If we decrease the fps for video, it can look like image animation rather than video. So, with more fps as it gives better results. Basically, fps tells us how many times it should update the ... Read More
Socket.io is a popular JavaScript library that allows us to communicate between the server and the client. We can create an instance of socket.io on the client and server sides and listen to or emit the events from both sides. Also, we can listen to the event emitted from the server on multiple web clients. In real-time, we can use the socket.io library to create chat applications and online games requiring bi-direction communication. For example, if you have observed while playing chess or Ludo, it allows us to talk with our opponent. In this tutorial, we will learn to configure ... Read More
We can use JavaScript to change the behavior of the web page. Every browser has a default scrolling speed when users scroll using the mouse wheel. However, we can control it using JavaScript. We can also use the mouse wheel to zoom in and out of web pages. In such cases, we require to reduce the mouse wheel speed. Furthermore, developers sometimes require a scrolling speed limit, such as on website rules, so that users can read it properly. In this tutorial, we will learn different ways to control the mouse's wheel speed. Syntax Users can follow the syntax below ... Read More
What is LiveLeak? LiveLeak is a video-sharing website where users have the option of uploading videos and sharing them among their contacts. The videos posted on the website were related to current events, war scenes, politics, etc. These videos were posted from all over the world. Currently, LiveLeak is shut down after 15 years of operation. The website consisted of videos of real violence which also included the execution of Saddam Hussein. Why LiveLeak Alternatives? LiveLeak has been banned because of its content. There are some other disadvantages of this website − The website included content full of violence ... Read More
A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. A line is a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions. In this article we will check if a given line touches a circle or intersects it using java. We will be given with the centre coordinates and radius of a circle along with equation of the line. We need to check if the given line collides with the circle or not and hence three ... Read More
A polygon is a 2-dimensional closed shape that has at least 3 sides. Depending on the number of sides, relationships of the sides and angles, and other characteristics, polygons can be classified under different names like triangles, squares, and quadrilaterals. The convex polygon definition explains that one is a polygon whose angles are all less than 180 degrees each. That also means that the vertices, the point where two sides meet, all point outward from the centre of the shape. In this article, we will find if two convex regular polygons have same centre or not. We will take two ... Read More
A square is a two-dimensional shape which has four sides of equal length. The opposite sides of a square are parallel to each other and all four interior angles are right angles with diagonal of equal length. In this article we will check how to confirm if given four points form a square. We will be given a square with four points i.e. A, B, C, D as shown in the figure − We need to check from these points that if they form a square or not. To check this it should satisfy the following condition − ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Here we have given a matrix which contains set of elements including both positive and negative numbers and as per the problem statement we have to replace negative numbers with 0 and positive numbers with 1. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given matrix =-21 22 -23 24 -25 26 ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Triangular Matrix − A square matrix is called as a triangular matrix if all the elements above or below the diagonal of that matrix are zeros. Lower- Triangular Matrix − A square matrix is called as a Lower- Triangular Matrix if all the elements above the diagonal of that matrix are zeros. Here we have to print the lower triangular matrix. Let’s start! To show ... Read More
