Scala vs Java

April 12th, 2019 General

Scala and Java both are high level computer programming languages. A programming language is a set of instructions which consists of unique grammar of words, letters, special symbols, numbers etc which can be given to a computer for performing some specific tasks. The software, websites, games, web applications, system drivers, operating systems and other programming languages are developed using the programming languages.
Every programming language has its own set of rules and specific functions. As there are many languages spoken in the world like English, Hindi, Chinese and all have their own notations or symbols to represent the letters and words, this is the same in the case of computer programming languages.
Today as the technology demands are increasing very much like wise the demand of programmers, coders, software engineers, software developers, marketing experts, penetration tester, ethical hackers and much more are too arising. Many of the popular tech companies are now hiring employees with technical engineering degrees and programming skills.
Many big tech companies for example Google are now no more looking for college degrees but yes they require skills. To become a software developer, website designer, application developer or game developer you should know some high level modern day computer programming languages. Now, today as the technology world has revolutionized so, many new programming languages have been emerged. So, it becomes very important to choose the best programming language suitable for your application or software development progress.
The needs, reliability, speed of execution and many factors are important for deciding the best and most suitable programming language. A good programmer knows better the specialty, limitations and usage of various programming language. So we are going to compare between two very popular and very useful programming languages i.e. Scala and Java.

High Level Programming and Oops

Computer programming languages are mainly divided into three categories as Machine Language, Assembly language and High level language. The historical programming languages which were used very first to develop programs in early stage computers were Machine language and it was very hard to learn and program. We have to write many codes and syntax for performing simple tasks and fault detection was also very difficult in the old programming languages.
The new stage programming languages like Scala and Java are high level programming languages. High level programming languages have easy and human readable syntax. We need extra components like compiler and interpreter in the case of High Level Programming languages.
A new type of programming concept i.e. Object Oriented Programming has a lot of features like data encapsulation, inheritance, reusability of code and polymorphism. These integrated features make programming very easy for the programmers and that’s the reason why programmers prefer using Object Oriented Programming languages like Scala and Java.

Scala

If you need a programming language which has all capabilities and features of an Object Oriented Programming language also with functional programming features then you should go for Scala. Scala is a general purpose computer programming language which is pure Object oriented and is also influenced by the Java programming language. Scala was founded in the year 2003 by Martin Odersky.
This programming language has a distinctive feature from other modern day programming languages known as Scalability thus it is named Scala. It provides all features of an Object Oriented Programming language and functional programming language with scalability. Get more results by typing less syntax. After it was launched in 2003, Scala has gained lot of popularity among the programmers and now its demand is very much.
The complete package of object oriented and functional programming in Scala imparts direct and fast syntactical support for various unique features present in it which are very unique in the case of Scala. Some of the mostly common used features are like:

  • Currying: A single argument can translate multiple arguments in the series of functions.
  • Type Interference: You know what the Scala programming language is very intelligent and this intelligence reduces the efforts made during the programming. You don’t have to mention the return type of function and data types in a clear and detailed manner these kind of stuffs will be accomplished by the programming itself.
  • Immutability: In Scala the already declared variables values can’t be modified, this feature is known as Immutability.

Some function literals like function0, function1 and much more are unnamed.

Java

Java has always remained in the list of most popular computer programming languages. The beginner level and basic techniques of Java are taught in many of the schools. Java is a standout amongst the most prevalent and broadly utilized programming language and stage.
A stage is a situation that creates and run programs written in any programming language. Java is quick, solid and secure. From work area to web applications, logical supercomputers to gaming comforts, mobile phones to the Internet, Java is utilized in each niche and corner.
Java which has been described to be ca general programming language which has all the features of an Object Oriented programming language. The main initiative behind developing Java language is to provide programmers and application developers the freedom to write once and read anywhere. The Java compiled codes can be read and used in various platforms supporting Java there will be no requirement of recompilation.

Java is invented by James Gosling of Canada at the Sun Microsystems and was then discharged from center segment of Sun Microsystems’ Java stage in 1995. The very first and reference usage of Java compilers, virtual machines, and these kinds of the class libraries were very firstly closed by Sun which has been under some restrictive licenses.
At the time of May 2007, with consistence with the details of the Java Community Process, the company now relicensed a large portion of its Java innovations under the GNU General Public License. In this mean time, others have created elective executions due to the Sun advancements, for example, the GNU Compiler for Java ,GNU Classpath and IcedTea-Web.
The most recent adaptation which is Java SE 12, discharged in March 2019. Since Java 9 is never again bolstered, Oracle encourages its clients to “promptly change” to Java 12. Prophet discharged the last open update for the inheritance Java 8 LTS, which is also meant to be free for business use, in January 2019. Java 8 will be bolstered with open updates for individual utilize around at any rate December 2020. Prophet and others “exceedingly prescribe that it is always better that you uninstall more seasoned forms of Java” because of genuine dangers because of uncertain security issues.

Which side to go for?

Scala gives you the advantage for Functionality Programming feature
For getting better output and getting stability in the development environment while programming the functionality programming feature of Scala comes into play. Make coding mixed with many types of inheritance, mutable data structures and much more capabilities. It ensures security, stability and safety. Easy and simple detection fault analysis is also a good feature integrated with Scala.

Asynchronous processing
Scala has the special feature which is unavailable in Java. Scala is designed to deliver for an asynchronous action. Unavailability of this feature makes Java usage very limited. Programmers therefore find a great advantage to work in Scala.
Many built in functions for fast work
Scala comes preloaded with many functions so that the efforts made for building new functions is reduced which is surely a good thing. Third party APIs has the option from where you can use the built in functions and you are not required to create them from scratch.
Avoid Deadlock
If you are a programmer then you have must encountered Deadlock many times so it is not that Scala abolishes it totally but can reduce it to very much extent.

Conclusion

You can clearly notice the differences between the codes of Scala and Java. In terms of scalability and more advanced features Scala wins the game because Java is bit complex programming language as compared to Scala. Java is a statically typed programming language.
Scala provides programmers ease to write and that is the reason why today its demand is rising rapidly. Scala and Java both are High Level programming languages and all have the features of Object Oriented programming. You can’t compare these programming languages among themselves and choose the best out of them. All have their different distinctive features which can be used for different types of programming environments.
Every programming language is best in their field. A good programmer overviews the environment and selects the best programming language for it.
