What Should You Choose Between Golang and Java?

Comparing Golang and Java is an interesting exercise, as both are widely used and respected programming languages. It is worth discussing the relative merits of each language and whether one is superior to the other. Additionally, it is important to consider the relative difficulty of learning each language and whether Golang has the potential to eventually replace Java. Let us explore these questions in more detail.

For over two decades, Java has been regarded as a leading force in the software industry, firmly establishing itself as a go-to for backend development. In comparison, the programming language Go (or Golang) is relatively new to the scene, having only been around for a few years. Nevertheless, it has been rapidly gaining traction and is quickly becoming a popular choice for developers.

Go and Java have become two of the most widely used programming languages by developers all over the world. Both are often used for server-side web applications, but they are also regularly used for tasks such as learning time, web development, performance, and providing rewards for developers. The competition between the two languages is intense, and it is constantly evolving in order to meet the needs of today’s developers.

The parallels, distinctions, and business uses of each language are highlighted in this piece.

Let’s get started.


Go, sometimes known as Golang, is a Google open-source language that debuted in 2011.

Golang, like Java, is a statically typed, multi-paradigm, compiled general-purpose programming language.

Golang’s syntax is modelled off of the ‘C’ programming language, as the original compiler for Golang was written in C. This allowed for the language to be self-hosted, which means that the compiler for Golang is also written in Golang itself. This enables the language to remain self-hosted, thus allowing for continued development and support.

Golang is a programming language designed to facilitate concurrent programming on contemporary multicore computers, allowing multiple tasks to be executed simultaneously. Additionally, its delayed garbage collection system manages memory efficiently, helping applications to run at a faster rate.


Java is a general-purpose programming language that is statically typed. Java was created and distributed by Sun Microsystems in 1995.

Despite its former status as the language of choice for server-side applications, Java is now used in hundreds of applications across the globe. Its widespread use is attributed to its ability to run on a variety of platforms, from legacy software on servers to modern data science and machine learning applications. Java is an incredibly versatile language, making it a great choice for developers who are looking for a reliable and adaptable language.

Due to the wide recognition of Java amongst developers, there are a variety of pre-existing modules and programs available to utilise. This combined with the abundance of developers in the field makes it a very straightforward language to code in.

Java is highly adaptable, as it can be executed on any computer with a Central Processing Unit (CPU). The Java Virtual Machine (JVM) decomposes the code into bytecode, a language similar to compiled languages, before compilation. This makes it possible to run Java programs on any system with a JVM.

Comparison between Golang vs Java

In the ongoing debate of Golang versus Java, it is difficult to determine which server-side language is superior. Both languages have roots in the ‘C’ programming language, and each offer high performance capabilities. To help assess which language is better for your needs, let us compare the two.

  1. Golang vs. Java: Key Differences

    Golang and Java both offer a variety of capabilities; however, when it comes to complex tasks, Java is the more suitable choice because of its object-oriented nature. Object-Oriented Programming (OOP) allows for code reuse and a more satisfactory development experience. Additionally, Java enables code to be self-analysed during runtime, which helps to identify errors.

    Golang is not an object-oriented programming language, and it lacks inheritance and reflection, making it less versatile than Java.

    One of the most noteworthy features of the Go programming language is its support for garbage collection. Garbage collection is also available in Java, though it is less powerful and efficient. Garbage collection is beneficial in managing large and complex codebases, as it helps to automate memory management, thus reducing the burden on developers.

    Additionally, the concurrent nature of Go is a noteworthy feature. Go’s implementation of ‘goroutines’ allows for functions or processes to be executed concurrently, providing more powerful capabilities than those offered by Java’s multithreading features.
  2. Performance of Golang vs. Java

    Despite the fact that Java is faster, Golang exceeds Java in most criteria.

    Java’s performance is adversely affected by the presence of its virtual machine, which enables Java to operate across any platform. This virtual machine, while advantageous in its ability to offer cross-platform compatibility, slows down the speed at which Java can execute its code.

    Golang has the advantage. Testing is simple with Golang, and the user experience is enhanced. Because it is related to ‘C,’ Golang is fast.

    Golang’s expedited performance is partially attributed to its efficient memory management system. Through the implementation of automated garbage collection, Golang alleviates the necessity for pauses to remove unwanted object references, ultimately optimising speed.
  3. Community vs. Golang

    Java is older and more widely used than Golang.

    In the past, Java was the most well-utilised server-side programming language, however, it now faces competition from both Python and Go (also known as Golang). Despite this, Java still boasts a larger following than Golang, making it a notable contender for the title of the most popular server-side programming language.

    Recruiting Java developers is a relatively straightforward process, owing to the large size of the Java development community. This expansive network of professionals provides a valuable resource for those in need of help, allowing Java developers to easily find assistance when needed.
  4. Golang vs. Java: Usage

    Golang is simple to use.

    Golang has a distinctive syntax which is comprehensible for English speakers, making it easy to write and read. Furthermore, the language provides 25 keywords, allowing for the definition of pre-defined actions and processes. Additionally, Golang’s library is minimal, thus allowing for quick and easy scanning.

    In addition, unlike other programming languages, Golang’s syntax does not employ brackets, parentheses, or colons at the end of lines.

    Java is a complex programming language that requires a developer’s complete attention. Its intricate syntax allows for greater flexibility and loose coupling, making it an attractive option for many developers. However, the complexity of the language means that mastering it requires a significant time investment and dedication.

  5. Golang vs. Java: Application

    Although both Java and Golang are server-side languages, their applications are not the same.

    Java is a cross-platform programming language because of the JVM, which enables it to function across platforms with little to no trouble.

    Golang offers a unique advantage in that code can be compiled into a single binary file that can be deployed on any platform; however, the process of creating a binary file for each platform can be time-consuming. Consequently, Golang’s reach may be more limited than other programming languages due to the additional time necessary for compiling binaries.

    Compiling the individual binary files for each platform takes time. So, if portability is important, Java is the best choice.

    Although Golang may not be the initial choice for developing a mobile application, it could still be advantageous to incorporate it in your technology stack if you wish to optimise your backend processes. Due to its capacity for concurrent programming, Golang is an optimal substitute for artificial intelligence tasks when either Python or Java are not available.

Which language is better for web development, Golang or Java?

Back-end web development is a strength of both Java and Golang.

Java is renowned for its platform-independence. The Java Virtual Machine (JVM) allows developers to create web applications for various operating systems, such as Linux, Windows, and OSX, without needing to recompile the code into a binary form for each system. Furthermore, the Java community is vibrant, providing developers the support, tools, and technology stacks they need to rapidly develop sophisticated servers.

Despite its initial success in backend web development, the primary use of Java has shifted towards backend mobile development, with Google now making extensive use of the language in the development of Android applications.

Organisations of a considerable size typically utilise Golang when deploying network servers. This is due to Golang’s compatibility with HTTP/2, as well as its capability to offer web development that is both versatile and straightforward, while also providing scalability. In contrast, Java does not have these characteristics.

Additionally, developers do not have to concern themselves with incorporating third-party web servers or libraries, since there are plenty of available tools for constructing web servers.


Java and Golang are both powerful, widely used and highly beneficial programming languages. However, they differ substantially. Java, which has been around for more than a decade, is an object-oriented language and is supported by a larger library and a larger community. Golang, on the other hand, is a multi-paradigm language and is more adept at dealing with concurrency. Though Golang is quicker, Java offers more features and a more comprehensive support system.
