Java vs Go

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

  • Cross-platform

  • Light streams of goroutines

  • Static analysis tools

  • Statically typed and it can be compiled to machine code
  • Limited library support

  • No generics

  • Implicit interfaces

  • Not a system language
  • Companies That Are Using Golang?

    • Uber
    • Medium
    • Slack
    • Google
    • Tokopedia

    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.

    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 vs Go: In Tabular Form

    Here you can see some differences between Java vs Go in tabular form.

    Java program code is a long but stable programming language. The language is based on object-oriented programming.Code of the Go language is compact. And the language doesn’t need parentheses, which reduces the errors.
    In Java, the garbage collector which is used is a traditional one.In Go, garbage collection is supported.
    Code in Java can be complex.As compared to Java its code is a simpler one.
    Java programming is compiled as well as interpreted. And the compiler code for Java is called bytecode.The Go programming language is compiled. Therefore, binary files are generated directly.
    Java allows inheritance.Go does not allow inheritance.
    New programmers may find Java challenging to learn.Compared to others, Go is fairly easy to learn.
    Generics are available in Java.Generics are not available in Go programming.
    The Java language does not support pointers.In Go, pointers are used.
    Java supports implicit type conversion.Go does not support implicit type conversion.
    Java is one of the oldest and most well-known programming languages. Thousands of developers are using it across the globe.The developers of Go are making new improvements in it because it is a new programming language.
    In Java, function overloading is possible.Overloading functions is not permitted in Go.
    Do-while and while statements are available in Java.While and do-while statements are not available in Go.
    Constructors and destructors can be used in Java programming.Constructors and destructors don’t exist in Go classes.
    For larger projects, Java is best.For smaller projects, Go is best.


    In this blog, we have discussed Java vs Go. And, it is very useful for the students to understand the essential differences between the terms Java vs Go. And we hope that now you should know all about Java vs Go. And you can decide which one is best for you.

    Is go harder than Java?

    No, Go is not so harder. As Go makes it easier to develop correct and efficient code (than Java or Python). But, It’s not simple to pick a programming language. The individual aspects of a language may appear to be fantastic at first glance, but seeing the flaws requires time and expertise.

    Does Golang have a future?

    Golang is without any doubt the programming language of the future. So, if you are interested in Golang, you should take the initial steps and try to learn it. The demand for expertise in this field will only increase in the future years.
