Abstraction: Decoding Abstract Classes in Java

Abstraction: Decoding Abstract Classes in Java

In this post, we explore Abstract Classes, an essential part of abstraction in Java. We'll build on concepts discussed earlier and examine how abstraction simplifies complex systems. Abstract classes serve as a blueprint for other classes, allowing us to focus only on relevant details while hiding unnecessary complexity. Let’s dive deeper into what abstract classes are, why they exist, and how they are used. What is an Abstract Class? An abstract class is a class that cannot be instantiated on its own. It’s designed to be extended by subclasses that provide concrete implementations for its abstract methods. In other words,…

Representing and Manipulating Information in modern computer – Part 1

Representing and Manipulating Information in modern computer – Part 1

As most of you might already know computer can only understand, store and process on a bit(0 and 1). But why?Well it turns out, two-valued signals can readily be represented, stored, and transmitted easily and more reliably than traditional base 10 number representation — for example, as the presence or absence of a hole in a punched card, as a high or low voltage on a wire, or as a magnetic domain oriented clockwise or counterclockwise, etc. Morever, a single bit is usually not very helpful in representing anything meaningful in computer but once we combine a sequence of bits,…

Next.js 15 : Incremental Static Regeneration (ISR)

Next.js 15 : Incremental Static Regeneration (ISR)

With Incremental Static Regeneration (ISR) Incremental Static Regeneration (ISR) in Next.js provides a powerful approach to combine the best of static and dynamic content. By enabling static content updates without recreating the entire site, ISR allows for a more scalable and efficient way of handling pages. We can significantly reduce server load, handle large volumes of content, and ensure users see up-to-date information without waiting for full regeneration of all pages. We can update static content without recreating the entire site. We can reduce the server load by providing prerendered static pages for most requests.We can process a large number…

Copy The Other Rows in a Text File the Times Which Is the Number in the Last Row #eg65

Problem description & analysis We have a txt file txt.txt, as shown below: a brown frog leaps over a lazy dog the dog then chases it's own tail the tail is long and brown the brown frog goes for a swim 3 The following text file has N+1 rows, in which row (N+1) contains a number M, say 3. We are trying to generate a new file according to this file. The rule is that repeat row N M times and get an altogether N*M rows, as shown below: a brown frog leaps over a lazy dog the dog then…

Conditional application of chained LINQ queries

Conditional application of chained LINQ queries

I write C# and I'm a big fan of using LINQ to create nice, readable chains of operations to filter and transform data in a functional style. int HighestEvenNumber(IEnumerable<int> numbers) => numbers .Where(x => x % 2 == 0) .OrderByDescending(x => x) .FirstOrDefault(); Enter fullscreen mode Exit fullscreen mode Sometimes though, there are conditions where parts of the chain should be included or omitted, but breaking the chain to add an if-statement feels wrong and disruptive. Let's say our previous example should throw an exception if there are no even numbers in the sequence instead of returning the default int…

C# advanced: Exploring Tuples An Alternative to Anonymous Types

Meta Description:Learn how to use tuples in C# for grouping elements, returning multiple values, and enhancing code readability. Explore examples, key differences from anonymous types, and hands-on assignments at easy, medium, and difficult levels Understanding Tuples in C#: A Better Way to Group Elements Welcome to a deeper dive into a powerful language feature in C#: tuples. While anonymous types are useful for grouping data, tuples offer a more flexible way to organize and access multiple values together across your application. Let's explore tuples and see how they differ from anonymous types. What Are Tuples? Tuples have been around in…

Best Practices for Writing Clean and Maintainable JavaScript Code

Best Practices for Writing Clean and Maintainable JavaScript Code

1. Meaningful Variable and Function Names:Tip: Use descriptive names that clearly indicate the purpose of the variable or function.Example: Copy code // Bad const x = calculate(5); // Good const totalPrice = calculatePrice(5); Enter fullscreen mode Exit fullscreen mode 2. Descriptive Comments:Tip: Write concise but meaningful comments to explain complex logic or intent. Comments should clarify why something is done, not what is being done (which should be clear from the code itself).Example: // Bad // Loops through the array array.forEach(item => doSomething(item)); // Good // Process each item to filter out non-active users array.forEach(item => filterActiveUsers(item)); Enter fullscreen mode…

Tim Berners-Lee : The Man Behind the Web

The Man Behind the Web Sir Timothy John Berners-Lee was born on June 8, 1955, in London, England and is a British computer scientist credited with the invention of the World Wide Web. His work revolutionized the accessibility and sharing of information, thus making the internet an indispensable tool in life. Berners-Lee worked on the web in 1989 at CERN, which is the European Organization for Nuclear Research. His goal was to create a system to make it easy for scientists to share research papers and data effortlessly. This led to the creation of HTML, URL, and HTTP, which became…
