As we talk about the contemporary programming languages used for software development, Java has been a prevalent choice globally. And those who know Java are well versed with Java Virtual Machine (JVM). Its expertise and salient features have spread throughout organizations of all sizes and segments.

For the last few years, JVM does not rotate around Java alone, there are many other JVM languages that are getting well known. JVM is getting faster and more effective in terms of execution and performance. Hence, these JVM-based languages are facilitating developers in maximizing their Java skills and overcoming the shortcoming that they were facing.

This article runs you through the first five most popular languages on JVM and then the other JVM implementations. But, firstly, let us quickly understand what a JVM language means.

What Is JVM Language?

A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. – Wikipedia

A JVM-compatible language is a programming language that can execute perfectly on a JVM. JVM is responsible for loading, verifying, and executing Java bytecode. As the interpreter of Java, it showcases an abstract computing model. It offers both a compiler and an interpreter. The compiler does the code compilation along with bytecode generation and then the interpreter does the conversion of the bytecode to machine understandable code.

JVM offers its own individual instruction set and execution engine that does the manipulation of memory regions at run time. This offers a comprehensive execution infrastructure for applications to smoothly execute on it. The JVM setup is a virtual one since it operates on top of hardware and OS which is real.

The three components that JVM comprises are class loader, runtime memory, and execution engine. JVM talks about a specification in which the JVM working is mentioned. Its implementation is called Java Runtime Environment (JRE). It creates a runtime instance each time a Java command is written on the command line. JVM is responsible for loading, verifying, executing code, and then offering a runtime environment.

Features Of JVM
  • Garbage collection
  • Native memory tracking
  • Inbuilt security features
  • Complete compiler control
  • Effective memory management
  • Supports non-Java languages
  • Signal Chaining

Of the Above, Top 5 JVM Languages That Lead the Way

Java:

Java is a highly popular, class-based, object-oriented, general-purpose programming language that was developed initially by James Gosling at Sun Microsystems and is now owned by Oracle. It goes by the ‘write once, run anywhere concept because of which it has been steadily maintaining one of the top slots for years now.

It caters to a variety of applications like dynamic web apps, Android app development, game consoles, server-side development, embedded applications, IoT apps, scientific applications, financial/trading apps, Microservices-based apps, robotics, and many more. The Java code is first compiled into byte code which runs on Java Virtual Machine (JVM) irrespective of the fundamental architecture.

Scala:

Scala is a known, general-purpose, statically typed programming language that supports functional as well as object-oriented programming. It is a high-level language that offers static types to lessen errors in complicated applications. The JVM and JavaScript runtime helps in creating high-performance applications with good library support. It is highly compatible with the Java ecosystem.

Being an object-oriented language, Scala manages user demands with ease right from smaller scripts to huge systems. It is mainly utilized for data processing, web development, distributed computing, data engineering, etc. Since it is interoperable with Java, it leverages library support heavily. Since it is statically typed, it has a sophisticated type interface system.

Salient Features:
  • Modernized, concise, and high-level language
  • Inbuilt best patterns and practices
  • Immutability, lazy computation
  • Well-designed coding structure
  • Concurrency control
  • String interpolation
Companies Using Scala:

Verizon, Twitter, Airbnb, LinkedIn, Accenture, Glovo, SoundCloud, The New York Times, Coursera, etc.

Groovy:

The Apache Groovy language is a powerful, scripting JVM language that offers simplified code with dot-separated notation. It supports syntax for manipulation of collections, Strings, and JavaBeans. As a dynamic, object-oriented language, it can be utilized anywhere where Java is used. It combines new applications, Java modules, and existing Java applications.

It offers multifaceted capabilities in which it offers static compilation and static typing. It integrates seamlessly with any other Java platform offering strong features and scripting competencies, meta programming, domain-specific language, and functional programming.
