Is Scala better then Java , Why ?

Java is a language based on Object Oriented programming. Its objective is for the most part centered around to gather the data and to take the control of the given information. It tries to make applications accessible to regular clients with the assistance of realistic UIs and pattern related to object oriented, though then again Scala Programming simply takes after the conventional useful approach.

Scala not at all like Java, is a language based machine assembly. That implies, it is intended to keep running on a particular domain to some degree like the JVM and offers the mix of the practical and question oriented approach with the assistance of a compiler and a sort framework, examined at the compilation time which is again the same as Java, apart from that, it has a vivid syntax of high level languages for example like Ruby.

While the straightforwardness of the Java programming language has been a piece of its fame, but ironically it has likewise increased the complexity of this language. Indeed, you can compose anything in Java, however the lines of code required to do as such can be overwhelming. Programming in Scala, then again, has a marginally more unpredictable structure. Yet, in the event that you can compose a somewhat more mind boggling single line of code that replaces 20 “less difficult” lines of Java, which one is extremely more unpredictable?

In all actuality Java is regularly just much excessively verbose. In Scala, the compiler is staggeringly brilliant, so this maintains a strategic distance from the designer expecting to determine unequivocally those things that the compiler can induce. Think about, for instance, this basic “Hello World!” program in Java versus Scala:

Although there is not a huge difference in the syntax of both of languages, yet we can see that the Scala syntax is less verbose in this hello word example.



While utilizing Java language in the program, engineers are required to compose longer queues of code to achieve normal assignments. In any case, Scala empowers software engineers to achieve the assignments without composing longer queues of code. Further, it encourages developers to make the code more composed, precise and reusable. Such a significant number of software engineers decide on Scala to build up a brief, precise and viable code base.


In spite of helping software engineers to achieve assignments with less code, Scala has a more mind boggling structure than Java. It expects engineers to compose a lower number of single line however complex code. Then again, Java empowers engineers to compose longer queues of basic code. Such huge numbers of novices think that its less demanding to learn Java than Scala.

Structure of the code

Scala have a high rank in syntax structure and language feature as compare to java. In any case, despite everything it has various structures that are not accessible in Java. For example, Scala can access case classes. The profoundly organized nature of Scala additionally empowers software engineers to change over it from simple language to Domain specific language. Therefore, the software engineers have alternative to redo Scala’s look and feel as per the particular needs of their design.


As per numerous sites, Scala is speedier than Java. A few software engineers even claim that Scala is 20% quicker than Java. Both java and Scala are keep running on JVM. So their code must be gathered into byte code before running on JVM. Yet, Scala compiler have the ability to support an enhancement method which is known as the tail call recursion. The advancement makes the Scala code aggregate speedier than Java code.

In general, both Java and Scala can be utilized in order to build a large project. However, each programming style has its own particular qualities and shortcomings. So it is critical for software engineers to remember that the particular needs of their task, while looking at the two programming styles.
