Scala vs. Java: Differences

The number of programming languages available to today’s programmers is remarkable. But when you’re unsure about which language to choose, having too many options becomes an issue. The two of the top 20 programming languages used today, Java and Scala, will be compared in the following paragraphs.

Describe Java

Java is a multi-platform, network-centric, general-purpose, object-oriented programming language. It serves as an application development platform as well as a programming language.

Java applications’ source codes are translated into bytecode, which is independent of the architecture and is supported by all Java virtual machines (JVMs).

The Benefits of Java

A programming language cannot remain relevant for long unless it provides a large and usable set of features. Here is a list of Java’s advantages:

  • It’s an extremely secure and sturdy language.
  • Java is excellent for developing object-oriented programs.
  • Java allows you to write code once and execute it on almost every platform.
  • It is backward compatible, thus once code is developed, it may be executed at any time.
  • Because Java has a garbage collector, programmers are not required to manage memory.
  • Java is simple to learn.
  • It has been in operation for almost 20 years, thus there are several web resources to support it.
  • Java provides multithreading, which enables software to accomplish many tasks at the same time.
  • Java is incredibly popular and can be found almost anywhere.

The Drawbacks of Java

No language is flawless, and Java is no exception. Although it has been around for a long and has been updated multiple times, certain difficulties remain. When weighing Sala vs. Java, you should be aware of some of Java’s significant limitations.

  • Java requires more memory and runs far slower than natively built languages such as C or C++.
  • Java’s default GUI apps, built in Java and using the Swing framework, vary significantly from native programs.
  • It consumes more memory.

Describe Scala

A general-purpose, high-level, statically typed programming language called Scala combines functional and object-oriented programming. Scala may be used to create applications for multiple platforms even though it is usually utilized with the JVM (Java Virtual Machine) environment. It includes native platforms that make use of JavaScript and Scala-native runtimes.

Why Scala Is Better

Scala offers a lot of advantages in this regard. A few of its advantages are as follows:

  • Scala eliminates boilerplate code due to its exact syntax. Compared to Java-based equivalents, Scala applications need less code.
  • It is both an object-oriented and functional language. Scala is an excellent option for web development because of this mix.
  • Java code may be executed using Scala.
  • Statistical abstraction is safe and consistent because of Scala’s powerful type system.
  • It’s simple to learn, particularly for programmers who have experience with object-oriented languages like Java.
  • Building fault-tolerant, highly parallel systems using Scala is a breeze.
  • When backed by technologies like Apache Spark, it’s perfect for data analytics.

Inconveniences of Scala

Like Java, Scala has several drawbacks, such as:

  • Particularly when compared to Java, there isn’t much of a community for it.
  • Not much backward compatibility is provided by Scala.
  • Despite being praised for its ease of learning, Scala has a higher learning curve since it includes ideas and functionalities that many programmers are unfamiliar with.
  • The IDE plug-ins in particular show how immature and less complex Scala’s development tools are than Java’s.

How Differs Scala From Java?

The genuine comparison may be found right here. Even if some of these topics have previously been covered, we’ll describe them once again for more precise comparison.

  • Scala is a combination of functional programming, statistically typed, and object-oriented languages, whereas Java, is a general-purpose, object-oriented programming language.
  • Java objects are functions, but variables in Scala are functions
  • When doing everyday operations, Java needs multiple lines of code, but Scala just needs a few lines of code. Scala code is written in half as many lines as Java code.
  • In contrast to Scala, which has a steeper learning curve and more sophisticated syntax, Java offers backward compatibility. Scala does not.
  • The “lazy evaluation” feature of Scala enables programmers to postpone time-consuming operations until they are required. Java lacks such a feature.
  • Java does not allow operator overloading, while Scala does.
