let's explain object-oriented programming (OOP) concepts:


1. **Classes and Objects:**

   - Imagine a class as a blueprint or template for creating objects. For example, think of a class called "Car" that describes what a car is, such as its color, brand, and model.

   - Now, an object is like a specific instance created from that blueprint. So, if you have a class "Car", you can create objects like "MyCar", "YourCar", each with their own unique characteristics.


2. **Encapsulation:**

   - Encapsulation is like putting things in a box and only allowing access through certain ways. In OOP, it means bundling data (variables) and methods (functions) that work on the data together within a class.

   - For example, in our "Car" class, we might have variables like "color" and "model", and methods like "startEngine()" and "stopEngine()". These are encapsulated within the "Car" class.


3. **Inheritance:**

   - Inheritance is like passing on traits from parent to child. In OOP, it allows a class (child) to inherit properties and methods from another class (parent).

   - For example, if we have a class called "Vehicle" with common properties and methods for all vehicles, we can create a class "Car" that inherits from "Vehicle" and then add specific car-related properties and methods.


4. **Polymorphism:**

   - Polymorphism means having many forms. In OOP, it allows objects of different classes to be treated as objects of a common parent class.

   - For instance, if both "Car" and "Bike" classes have a method called "move()", they can each implement this method differently. But when we call "move()" on an object of the parent class "Vehicle", it can behave differently based on whether it's a car or a bike.


5. **Abstraction:**

   - Abstraction is like hiding the complexity and showing only the necessary features of an object. In OOP, it allows focusing on what an object does rather than how it does it.

   - For example, when you drive a car, you don't need to understand the internal combustion engine's complexities. You just need to know how to use the pedals and steering wheel. This is abstraction - hiding the complexities of the engine.


These are the basic concepts of object-oriented programming explained in simple terms. They help in organizing code, making it easier to understand, reuse, and maintain.

Refresh an Angular Component without reloading the same Component

Image
A short trick for refreshing data in the same Angular components. This snippet will work in Angular 2, 4, 5, 6, 7, 8, and 9. Here two method and  you can add according to your needs you are working with Angular and need to refresh a component without navigation on another component without  using   window.location.reload()    or   location.reload() ,  you can use the following code in your project: 1. using constructor in the same page(component) reload: any; Then, add this code to the required component's constructor . this . router . routeReuseStrategy . shouldReuseRoute = function () { return false ; }; this . mySubscription = this . router . events . subscribe (( event ) => { if ( event instanceof NavigationEnd ) { // Trick the Router into believing it's last link wasn't previously loaded this . router . navigated = false ;   } }); Make sure to ...

.NET Core vs .NET Framework: How to Pick a .NET Runtime for an Application

Image
Is  .NET Core  the next big thing? We’ve been toying with it for a while now, and we tend to think that it is. In fact, we predict that there will be a  huge demand  for developers skilled in this technology in 2018-2019. But how does it differ from the .NET Framework, and what do you need to know to use them effectively? In this post, we’ll explain the main differences and offer some guidance on how to make the best use of each. Historically, the .NET Framework has only worked on Windows devices. The Xamarin and Mono projects worked to bring .NET to mobile devices, macOS, and Linux. .NET Core provides a standard base library that can now be used across Windows, Linux, macOS, and mobile devices (via Xamarin). There are four major components of .NET architecture: Common language specification  (CLS) defines how objects are implemented so they work everywhere .NET works. CLS is a subset of Common Type System (CTS) — which sets a common way to describe all ...

multi color initial(Avatars) if img not available in Angular it's work angular 2,4+ all versions

Today I will show two methods apply background-color in initial Method 1: here I will show dynamic colors using random calls step 1: create a component and define color array list in .ts file public circleColor: string; colors = [ '#6930c3 ', // French Violet '#0096c7', // Blue green '#FFFF5C', // Laser lemon '#FF3366', // Radical red '#F49F0A', // Tagrine '#25a550', // Green '#03312E', // Rich black ]; step 2: ngOnInit() { const randomIndex = Math.floor(Math.random() * Math.floor(this.colors.length)); this.circleColor = this.colors[randomIndex]; } step 3: In .html <div class="circle" [ngStyle]="{'background-color': circleColor }"> // change color // <img *ngIf="!showInitials && showComponent" src="{{photoUrl}}" onerror="showInitials " class="initials">{{ initials }} ...
