  Today’s software engineersneed a toolkit that allows a choice when writing code between object-oriented or functional, immutable or mutable, high-level abstractions or low-level speed. Scala is a language that has evolved fromitscreationin2003andprovidesthischoice.hence,itisa popular choice for constructing applications that are revolutionisingtheIndustry. Scala is a type-safe JVM language that incorporates both object-oriented and functional programming into an extremely concise, logical, and extraordinarily powerful language Concurrent programming Functional Language March- 2016 What Is Scala?

Prosofscala consofscala Simple and straightforward syntax. Scala typically requires two-thirds less codes than Java. The syntax is also more flexible. For example, you can leave out periods between method calls so that the code is more human- readable and easier to understand. Inherently immutable objects. Scala’s programming language reduces many thread-safety concerns that spring up in traditional Java applications. Fast implementation speed. It allows for quicker implementation and enhanced performance. Hard to learn. Syntactically, Scala is significantly different from traditional Java. Furthermore, it presents a completely different programming paradigm—requiring a higher level. Low ease of adoption. When coding with a team, it’s rare to find everyone writing purely in Scala. You need a team of eager adopters for Scala to be feasible. Limited backward compatibility. Each major new release of Scala is incompatible with the previous version. List<Integer> ints = new ArrayList<Integer>(); for (String s : list) { ints.add(Integer.parseInt(s)); } val ints = list.map(s => s.toInt) Scalavs.Java There are some tricks in Java to shorten the code a bit, but not in standard usage. Now consider a case where we have a list of strings that are numbers, but we want to convert that list to a list of integers: ScalaonEduonix? Lectures 23 hours 6 30 Day Money-Back Guarantee!
