Golang vs Java

Today, businesses of all sizes and nature need a software application. Running any business in an efficient manner requires them to be online in an impactful manner and for that, a good programming language makes the base. And that is how we come to this blog's title- Golang vs Java.

While both these are highly revered programming languages, there is a distinct line of difference that sets them apart. The goal here is to cover enough information about each of them so that when it comes to picking, you know just which one to go for. Of course, you could choose to learn them both if you wish to tap into unprecedented opportunities.

Here, however, we have Golang vs Java, highlighting their differences and business applications. Let's get started!

Golang vs Java: An Introduction

Java has been around for quite a while and has etched a place for itself as a powerhouse for backend development. Golang is relatively new but has become a widely used language in such a short span of time. Both are used globally on a large scale and the competition is to see which one's a better fit for server-side web applications.

Before we go there, here's an individual definition of both.

What is Golang?

Go language, more popularly referred to as Golang, was launched in 2011 by Google. It is quite similar to Java in the sense that it is a statistically typed, compiled, general-purpose, and multi-paradigm programming language. This concurrent language is built basically for multicore processors. This means that it has the potential to perform several tasks at the same time.

What is Java?

Released in 1995 by Sun Microsystems, Java is a general-purpose, statistically typed programming language. While it was initially preferred for only server-side applications, its usage and use cases have expanded with time. Today, hundreds of applications use Java globally, making it a rank high on much loved programming languages.

Go Language vs Java: An In-Depth Comparison

It's time to dig deeper into what makes one different from the other. This section covers an in-depth comparison of Go language vs Java, one feature at a time.

  1. Compilation 

Golang: Deployment is simpler as it is compiled on a single binary. Containerized and microservices applications benefit more from it.

Java: It compiles to the bytecode that is running on the JVM, hence facilitating it to execute. The outcome can be more challenges in deployment situations.

  1. Memory Consumption

Golang: Due to its small footprint and memory efficiency, it is apt for apps having limited memory resources. Memory management is also an easy task for developers using Go.

Java: Java is certainly more efficient than Go, but at the same time, can also consume more memory because of the overhead on JVM. This language also has garbage collection and offers control over memory management to developers.

  1. Golang Performance vs Java

Golang: It offers an exceptional runtime because of its garbage collection and efficient runtime. Performance-critical applications usually pick this language because of its native machine code.

Java: While it offers good performance, it does rely on a JVM or virtual machine, adding some overheads.

  1. Language Design

Golang: It became so famous so soon because of its minimal design and simplicity. In fact, the main reason behind developing it was to reduce the complexity of programming. With its features like shorter syntax, it facilitates in developing a more maintainable and cleaner code.

Java: It has an object-oriented nature and complex typing. While this leads to the code being highly organized, it also arises to need for a boilerplate code.

  1. Speed 

Golang: Go showcases a fast startup time, especially when compared to Java. Hence, projects with command line or serverless tools generally opt for Go language.

Java: Java typically showcases a slightly longer startup time because of JVM initialization.

  1. Concurrency

Golang: Go is supported by Gorountines and channels. The former are short strings that render it simpler to write concurrent codes. The latter, on the other hand, simplify communication between different goroutines, making it easier and safer to manage concurrency.

Java: Its threading model supports concurrency. However, managing threads can be said to be a cumbersome and error-prone task. Many of its libraries also aid in concurrent programming.

  1. Dealing with Errors

Golang: This language uses a simple error handling model that has return values. Hence, it is easier to find errors and deal with them.

Java: Exceptions are used for error handling, which may also lead to highly unpredictable code in certain situations.

  1. Microservices

Golang: Its built-in concurrency support and simplicity renders it a great pick for microservices with the need to handle various concurrent requests.

Java: Its mature library and ecosystem can also be skillfully used for microservices. This is especially true for large projects.

  1. Ease of Learning

Golang: Golang is certainly much easier to learn and use, especially when compared to Java. Even beginners give preference to this language.

Java: Java is a complicated language, which can take a while to learn and even longer to master.

Conclusion

Both Java and Golang are popular, powerful, and extremely useful programming language. However, there is still a strong line of difference that we hope this blog on Golang vs Java must have made a bit clearer. Both are two unique languages that are made with different concepts and goals in mind.

While Java is around 30 years old, Golang is half its age and yet, here we are comparing these two. This is a clear indication of Go's popularity and its abundance of features. Which one you ultimately pick depends on the kind of the projects you/ your company usually tend to. But one thing is clear and that are endless opportunities in both the scenarios.

Frequently Asked Questions for Golang vs Java

Question. Is golang faster than java?

Is Golang faster than Java? Well, Golang is certainly faster than Java as it is lightweight in nature. Hence, it uses fewer memory and resources. In Spite of that, Java is used heavily for projects globally.

Question. Is it better to learn Golang or Java?

There are various factors to consider before deciding whether to learn Golang or Java. It is true that Golang outperforms Java in almost all metrics and comparison basis, making it rapidly accelerating towards the top programming languages used globally for projects of all sorts.

Question. Is Golang going to replace Java?

Whether Golang will replace Java or not depends on various factors. While Go is speedily being chosen for many projects, there is still a huge fan following of Java. Programmers prefer Java because of the strong ethics and nature it provides. So, it is quite unlikely for Go to replace Java.
