Golang vs. Java: Which should you choose?

Quick Brief :

Since it has been around for a while, Java has built its reputation as a software industry powerhouse for backend development. On the other hand, Golang is a relatively new language. Both Golang and Java are widely used by developers. Direct competition exists between the two languages for dominance of server-side web applications. They contend with one other in a variety of other areas as well, including learning time, web development, performance, developer payout, and others. The comparison of Java and Golang pits two super popular quick backend programming languages. Is Java better than Golang? Is Golang more complex than Java? Are they similar? Let's explore this through this blog. 

What is Golang or Go?

Rob Pike, Robert Griesemer, and Ken Thompson created the statically typed programming language Go at Google. Golang or Go is syntactically similar to C, but it only has concurrency in the CSP manner, structural type, garbage collection, and memory safety. Golang is a multi-paradigm, statically typed, compiled, general-purpose programming language, much like Java. 

Because the language's compiler was created in C, Golang's syntax is similar to that of 'C'. But now that it is written in Golang, the language can continue to be self-hosted. 

What is Java?

Java is a general-purpose, statically typed programming language. In 1995, Sun Microsystems was created and made available in Java. The release of Java was 25 years ago—how quickly time passes! Since then, the language has been established in the IT industry and seized the initiative in backend development. 

Java was created with the intention of making the development process easier, embodying the "write once, run anywhere" idea. And developers have definitely jumped at the chance to write code that doesn't require recompilation to run on different platforms. Just a few successful platforms created with Java include Facebook, Amazon, Twitter, eBay, and LinkedIn. 

The preferred language for server-side apps used to be Java, but that is no longer the case. Despite this, it is used in countless diverse applications across the globe. Java is used on a variety of platforms, including contemporary data science and machine learning applications as well as dated legacy software on servers. 

Similarities Between the Two

Excellent Profiles

Both Java and Go offer profilers that track a variety of data, including memory usage, time complexity, and the length of function calls. They enable program optimization. You have to admit that this is a helpful feature if you operate a business! You wish to reduce memory usage or speed up the execution of your app. In that situation, competent profilers excel. 

Multithreading Support

Java and Go are both multithreaded, which enables them to carry out several tasks concurrently. Notably, Go prevails in this contest because it is more efficient. That makes it the ideal option for processes that require a lot of processing power, like search engines in apps. 

Debugging and Testing

The success of your project depends on the speedy detection and correction of any app bugs through debugging. Due to the automation of the procedures, testing frameworks help to lower maintenance expenses. The testing is more accurate, and hardly any physical involvement is required. 

Golang vs Java: The Great Comparison


Both Golang and Java offer a wide range of functionality, but because Java is object-oriented, it is better suited for difficult jobs. Code reuse is encouraged by object-oriented programming (OOP), which also improves the developer experience. Java additionally enables runtime self-reflection of code to check for faults. 

Golang is less flexible than Java since it is not an object-oriented language and does not enable inheritance or reflection. 


Despite Java's speed, Golang performs better than Java in the majority of measures. 

Java's virtual machine for Java compilation is partially to blame for the lack of performance. Although this virtual machine enables Java to operate on any platform, it slows it down. 

Golang is in the lead. Testing is simple and the user experience is superior with Golang. Due to its resemblance to "C," Golang is speedy. 


Golang is very new and less well-known than Java. 

Java used to be the language used the most frequently for server-side development. Although Python and Java are currently vying for that distinction, Java still has a larger user base than Golang. 

Java developers are simple to discover for recruiters. Additionally, because the Java community is big and well-established, Java developers can readily seek advice from it. 


Golang's syntax also does away with the brackets, parentheses, and colons that programmers typically use at the end of lines, which is different from most programming languages. 

On the other side, Java is complicated. The use of Java demands a developer's whole focus. The advanced grammar of Java, however, allows for flexibility and loose coupling. 


Despite the fact that Java and Golang are both server-side languages, they have diverse applications. 

Java is a cross-platform programming language thanks to JVM, which enables it to operate across platforms with little to no hassle. 

On the other hand, the scope of Golang is constrained. For instance, Golang creates a binary file from code so that it can run on any platform. However, it takes longer than necessary to create a binary file for each platform. 


Both Java and Golang are robust, well-liked, and practical. They still differ greatly from one another, though. Java is more established, object-oriented, and has a bigger community and library. Golang handles concurrency better and is a multi-paradigm. Java offers more features and better support, while Golang is faster.
