Java vs Go: Every Difference That You’re Looking For

Both Java and Go are utilized by a vast number of developers all around the world. It can be tough to select between the two languages because they both provide server-side programming. In this blog, we’ll discuss about the differences between Java vs Go. So, before going deeper, Let’s start with a short introduction to each of these terms.

What is Java?

Java is a general-purpose, object-oriented programming language based on classes that is meant to have fewer implementation requirements. The Java programming language was created by James Gosling at Sun Microsystems and introduced as part of the Sun Java Platform in 1995.

For the development of applications, it is a computing platform. Java is quick, secure, and dependable. To construct the Java applications, it’s commonly used in laptops, data centers, gaming consoles, scientific supercomputers, mobile phones, and other places.

Pros and Cons of Java

    What is Go?

    Go is an open-source programming language created by Google and mainly it is designed with the goal of assisting in the development of simple, dependable software systems. Go’s main strength is its concurrency techniques, which make writing applications and exploiting multi-core architectures easier. It’s a garbage-collected, compiled, strongly-statically typed, concurrent language.

    Because of some of the decisions taken throughout its development, it’s a really intriguing contemporary language. For instance, the Type System has no type hierarchy despite the fact that Go includes methods and an OO programming style. Interfaces are the only method to accomplish this.

    Pros and Cons of Golang (Go)

  • It is fast

  • Code simplicity

  • Garbage removal

    Java vs Go: The Key Differences

    There are so many differences between Java vs Go, Let’s discuss some key differences:


    Java’s run time is a bit less than the Golang’s. And it is faster as it functions like C. It compiles to machine code and runs directly. Java must run the code twice: first, it must be converted to byte code by the JVM, and then it must be compiled into machine code. 


    If we talk about the speed in between Java vs Go. Go is a faster one than the Java. This is because Go’s code is not compiled using a virtual machine. It is immediately compiled into a binary file. Go is quicker because it does not need a virtual machine. However, the VM allows Java to run on a wider range of systems.

    Go is a simple and scalable programming language. It has excellent multithreading capabilities and easily manages concurrent activities, with lightweight threads called ‘goroutines’. It’s safe and up to date, making it suitable for cutting-edge technology.

    In contrast, Java offers portability and allows you to code once and execute anywhere. To make code operate in any application, the JVM interacts with the hardware. Launching the same line of code on a machine that is more complicated may not always be correct. It is the standard programming language for Android phones.


    Go is a language that is a simple one. It is easy to learn and designed to have good readability. And its features are limited to extend. Its purpose is to prevent mistakes, defects, and issues when running software. 

    Java provides a wide range of options, and developers have experimented with several capabilities or features that were added to the language later. Java includes all of the capabilities you’ll need to get started. For the developer’s convenience, it also supports third-party tools.


    Java is a programming language that has been around for more than two decades. Its characteristics have been influenced by the programming language. It has a lot of developer support, which has resulted in a powerful community. They are developers that come and go throughout time, but they are an active community that can help you solve your difficulties. 

    In contrast, Go has a vibrant community that is modest but expanding rapidly. There are several resources and example codes to choose from. If you come into an issue, it’s more probable that you’ll be able to solve it with the aid of other developers who have been down the same road before, assuming it’s been documented.


    Go’s syntax is quite unique. For English speakers, the language is simple to understand and write.

    Importantly, the Go language contains 25 keywords that can be used to represent predefined actions or internal processes.

    Go is, as you can see, easy to work with. Go’s library, which is small, makes it easy to browse through.

    Go’s syntax, unlike other programming languages, does not use brackets, parentheses or those awkward colons programmers might have to add at the end.

    Go can be summarized as an imperative language. It wants to do the right thing.

    This is a great advantage for developers because Go is very easy to use. The downside is that Go lacks complexity and dependency is inevitable.

    Java, in turn, is a declarative language. You have more freedom to express yourself. Java development requires full attention of the developers.

    This is not necessarily a bad thing. Working with more complex syntaxes can have its benefits, such as flexibility and loose coupling.

    If we talk about who is the winner: None — Java vs Go to be used depends on your requirements and the best fit for your project. There is no clear winner.

    Memory management

    If we talk about memory management in Java, it is handled by the JVM, which contains the garbage collection for automating memory management tasks. 

    In contrast, Golang is compiled to machine code and directly runs, which results in the memory management option, which is the best one. 

    Golang uses a reference registry and interacts with external C code during runtime. The real pointers are hidden from the execution system. Analyzing the RAM allocated might provide useful information. And in Java vs Go, Go comes on the top. 


    Java may seem to be a safe language. Although Java does not provide security, some features of the language can help you avoid common security problems.

    First, Java does not have pointers as C. And a pointer is an object which stores the memory address for another value. This value could allow unauthorized access to memory.

    It also has a Security Manager, which is a security policy that can be applied to each application. You can set access rules. This allows Java applications without risk to run in a Sandbox.

    The checksum database is one of the most important security features in Golang. This database stores checksums that are used to confirm that the Go module files have not been deleted. This feature builds trust, and is why Go modules and Go version control have become so popular.
