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

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

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

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

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

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
