Scala vs Java: A detailed comparison between both Scala and Java

scala vs java Scala vs Java: A detailed comparison between both Scala and Java Here in this blog, CodeAvail experts will explain to you about​ ​Scala vs Java​ in detail.

Scala vs Java Scala and Java names look common to so many people, what separates them?. Both Java and Scala have their own features. Java​ ​is a

general-purpose computer programming language that is object-oriented, class-based, concurrent, etc. Java applications select bytecode that can run on each Java virtual machine (JVM) despite computer architecture.

Scala​ is a multi-paradigm, high-level, general-purpose programming language. It is a pure object-oriented programming language. For example, that also gives support to the functional programming approach.

Also, there is no idea of primitive data as in Scala everything is an object. It is created to show the general programming models in a type-safe, succinct, and refine way. Likewise, In this blog, we have given a detailed difference between​ ​Scala vs Java​.

What is Scala?

It is a statically typed programming language that includes object-oriented and functional programming. Also, it essentially targets the Java Virtual Machine platform but it applies to write various platforms software. However, it

incorporates native platforms using Javascript and Scala-Native runtimes through Scala.

Features of Scala Here are the essential Scala features: ● Scala is statically typed ● Scala is object-oriented. But also it is a functional language. ● Enables you to execute Java code ● It is a short, strong language. And can immediately grow according to the user’s demand.

What is Java?

Java is a computer programming language utilized for general purposes and is object-oriented, concurrent, and class-based. By James Gosling it was developed in 1995 at Sun Microsystems, the organization later received by Oracle in 2009. The language is made so that developers can run it on all platforms that support Java without requiring to be recompiled.

Some features of Java Some of the essential Java features are: ● Java is highly Robust and Very Secure ● It describes an instance of a class like encapsulation, abstraction inheritance, polymorphism.

● In this case, it writes code only once and runs it on almost every computer platform ● It is created for developing object-oriented applications. ● Java is easy to understand. It has no complication in its features like an inheritance, pointer, operator overloading, etc. ● Java is a multithreaded language with automated memory management.

Significant differences Java vs Scala ● The variables of Scala are by default immutable type on the other hand variables of Java are by default mutable type. ● Java is a network-centric, multi-platform, programming language.

Whereas Scala is a static type programming language. ● Scala does not include static members. While Java includes static members. ● However, it does not give backward compatibility. But Java does give backward compatibility. ● Scala helps lazy evaluation. On the other hand, Java does not support lazy evaluation. ● The actor model is used in Scala for maintaining modern concurrency. Whereas for concurrency, Java uses the conventional thread-based model. ● Frameworks Scala are Lift and Play. On the other hand, Java frameworks are Grails, Spring, and many more. ● Scala promotes operator overloading. But Java does not support operator overloading. ● Because of the nested code, Scala is less readable whereas Java is more readable.

Scala vs Java comparison table Parameters

Scala

Java

Supported frameworks

Supports frameworks – Lift, Play

Supports Grails, Spring, much more

Support for Various inheritances

Supports various inheritances by using classes but not by abstract classes

Accordingly, Does not support various inheritances by using classes, but by interfaces

Compactness

Generally, more concise and compact

Comparatively bigger parts of code

Lazy evaluation support

Likewise, it Supports lazy evaluation

Thus, it does not support lazy evaluation

Designed for

It is created and produced to be both functional and object-oriented language. It supports an extensive type of functional programming features such as Immutability and concurrency.

Basically produced as an object-oriented language and started helping features of functional programming in current days. For example, it is not as effective as a functional programming language.

Interfaces

Traits – function like Java 8 interfaces

Java 8 interfaces try to connect the gap between interfaces and objects

Concurrency model

For supporting modern For concurrency, it concurrency it uses uses the conventional the actor model thread-based model.

URL rewriting

There is need for rewriting

Accordingly, Rewriting is not required

Static members

No static members

Generally, Includes static members

The static keyword

It does not include the static keyword.

Java includes the static keyword.

Readability

Because of its nested code, Scala is less readable.

However, Java is more readable.

Operator overloading

Also supports operator Do not support overloading operator overloading

Bug-free codes

No certainty about the bug-free codes

Code style

In Scala code is written The code is written in in a short form. long-form.

Likewise, Complete insurance of lesser defects

Compilation process

Therefore source code compilation is relatively slow

Source code compilation is faster than Scala

Process Compiling

The process of source code compiled into byte code is very late.

Accordingly, the process of source code compiled into byte code is quick.

Guide for backward compatibility

Scala does not help Likewise, Java helps backward compatibility backward compatibility

Variables types

Variables of Scala are by default immutable type.

But variables of Java are by default mutable type.

Treats

Any function or method given in Scala is they are used like they are variable.

Java uses functions as an object.

Calling method

Every operation in Scala on entities implemented using method calls.

Likewise, In Java Operators are managed separately and it is not done using the call method.

Conclusion In this case, Scala is a pure object-oriented programming language. By the way, that also gives support to the functional programming approach. There is no idea of primitive data as in Scala everything is an object. Therefore, it is created to show the general programming models in a type-safe, succinct,

and refined way. However, Java allows the developers to run identical code on different platforms.
