Scala | Multithreading

Reading Time: 2 minutes What is Multithreading Multithreading means we can execute multiple threads at once. We can also perform multiple operations independently and achieve multitasking. This helps us to develop concurrent applications. In Scala, a thread is a lightweight sub-process that occupies less memory. Let’s see how Scala creates threads and achieves multithreading. What Scala Thread Life Cycle Looks Like In between the period of creation and Termination of Continue Reading

Some Important Features of Scala

Reading Time: 3 minutes Scala is a programming language that supports both functional programming and object-oriented programming. It has powerful features. Scala language is based on java language so if you are aware of java it is easy to learn Scala Features of Scala Type inference Singleton object Immutability Lazy evaluations Case classes and Pattern matching String interpolation Higher order function Trait Rich collection set Type Inference There is Continue Reading

Scala Futures

Reading Time: 2 minutes We all know that parallel and concurrent applications are need of the hour. To write these applications, multithreading is used. Thread safety is very common problem when working on such applications. So, Futures gives an easy way to run one or more tasks concurrently in Scala. When we create a new future, Scala creates a new thread and executes its code. The result of the Continue Reading

Scala | Functions

Reading Time: 5 minutes A function is a collection of expressions that perform a certain task. We can divide a code in scala into separate functions, where each function must perform a specific task. We use functions to put some common and repetitive tasks into a single function, so instead of writing the same code again and again for different inputs, we can simply call the function. A function Continue Reading

File Handling and Operations in Scala

Reading Time: 3 minutes Today we will look into Scala File IO operations. So let’s start with the basic definition. File Handling is a way to store the fetched information in a file. File operations mainly include reading data from files or writing data into files. Here we will look into Scala read file and Scala write file programs. Creating and Writing to the file Scala doesn’t provide file writing Continue Reading

Scala Trait

Reading Time: 2 minutes Introduction: Scala trait is like an interface with partial implementation. Scala trait is a collection of abstract and non-abstract methods. You can create traits that have all abstract methods or some abstract methods and some non-abstract methods. Any variable declare using the val or var keyword in a trait gets implement internally in the class that implements the trait. A variable declared with val or Continue Reading

Why Prefer Scala Language

Reading Time: 2 minutes Learning languages is really about concepts and how to effectively use them in practice. Scala has a lot of great concepts that are way better than mainstream.This is the main reason to prefer scala. Scala was designed to look at how OO and functional could be combined in a language that started with the OO side. If you really want to do server-side work, Scala Continue Reading

Object-Oriented Programming in Scala

Reading Time: 3 minutes Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. Scala is also an Object-Oriented language and in this blog, we will see how we achieve that in scala. Classes in Scala Class is like a blueprint for a real-world entity which we call object in programming languages. It provides the initial values for state Continue Reading

Scala Traits in Simple words

Reading Time: 2 minutes In this blog post, we will talk about traits in Scala. Then we will discuss how is a trait different from abstract classes. Scala Traits A trait is similar to a partial implementation of an interface. A trait in Scala can contain abstract and non-abstract methods. We can make a trait with all abstract methods or some abstract methods and some non-abstract methods. Variables declared Continue Reading

Collections in Scala

Reading Time: 2 minutes Scala has a rich set of collection library. Collections are the containers that hold sequenced linear set of items. Collections may be strict or lazy. Lazy collections are collections that are not evaluated until they are accessed. Also, they can be mutable or immutable.   ArrayBuffer As we know that arrays are homogeneous and mutable. You can change the value but cannot change the size Continue Reading

Is learning Scala worth in 2022 | Tech

Reading Time: 4 minutes Sometimes it is tricky to make a decision about the new learnings one should pursue to elevate and leverage their proficiency levels in the ‘Languages’ space, especially in the big data ecosystem where plenty of languages are in use and a lot are being adopted at a very rapid pace. As the data is growing exponentially, so is the tech stack. If one looks around, Continue Reading

SCALA STRINGS IN SIMPLE WORDS

Reading Time: 6 minutes A string is nothing but a data type used in programming to represent text rather than numbers. A string is a combination of characters and can contain letters, numbers, symbols, and spaces. Scala Strings should be enclosed in double-quotes. For example, the word “computer” and the phrase “who invented the computer?” are both strings. A sequence of characters “abdj@nfi%*&23kh09i2^l” is also considered a string. In this Continue Reading
