Go vs Java: differences and similarities you should know

Here in this blog, CodeAvail experts will explain to you about Go vs Java in detail.

Java and Go both use widely programming languages around the world. Go, also recognized as Golang, is a procedural programming language. In 2007 it was developed by Ken Thompson, Rob Pike, and Robert but as an open-source language, it was launched in 2009.

Go vs Java

Griesemer Being an open-source language for programming, Go performs it easy to make efficient, simple and reliable software. By using packages programs collect, for effective dependencies management. On the other hand, Java is a computer programming language utilizes for general purposes and is object-oriented, concurrent, and class-based. Java is specifically intended to accommodate fewer implementation dependencies. 

Java Applications run on Java Virtual Machine. It is one of the most outstanding and important programming languages today. Java is secure, reliable and fast. To produces, software for various platforms Java programing language uses. Just read this article for a more detailed difference and comparison of both the programming languages. 

What is the Go programming language?

Go is an open-source programming language that gives it easy to make efficient, simple and reliable software. Syntactically Go is similar to C, but with structural typing, memory safety, CSP-style concurrency, and garbage collection. Because of its domain name, golang.org, the language is usually known as “Golang” but the usual name is Go. 

Pros of Go programming language

Go is quick as compared to other programming languages and compiles very fast. It involves automating memory management, garbage collection so it is not a job the developer has to do manually.

Go programming has documentation as a standard feature, which makes it easy for developers to code documentation. It also has a strong standard library covers a broad range of areas.

Go programming helps concurrency at the level of the language, meaning it allows likeness more efficiently than other languages. Several developers say they like Go’s style and simplicity. It is simple to understand and strives to be accessible to both reading and writing.

What is the Java programming language?

Java is a computer programming language utilized for general purposes and is object-oriented, concurrent, and class-based. By James Gosling it is developed in 1995 at Sun Microsystems, the organization later received by Oracle in 2009. The language is made so that developers can run it on all platforms that support Java without requiring to recompile.

Pros of Java programming language

It is one of the most common programming languages used by individuals today, and it is not tough to understand why. Likewise, Apps for Android, the world is leading mobile platforms, are completely built by the use of Java. Also, it is a staple of performance computing, used by 90% of Fortune 500 organizations.

It is comparatively simple to master with lots of reusable code already available. It is also platform-independent, thus it can simply move from one computer system to another or run the identical program on many of various systems.

Java is good, with lots of emphasis on early checking for possible errors. It is also continually growing, with the newest version – Java 9 – released in September 2017.

Significant differences between Go vs Java

Both Java vs Go demand are high and popular selections in the market; let us see some of the significant Difference Between Go vs Java:

  • Both languages deal with completely separate niches.
  • Pointers of Go restrict to Objects and arrays, they can give pointers to any type of values.
  • To present events like end-of-life and run-time, Go does not use exceptions. it uses errors to present these events.
  • Go gives garbage collection. Whereas Java, it does not support a full Garbage collection.
  • Java uses virtual methods by default.
  • Go helps complicated numbers as it has built-in support for that.
  • On Go, Function overloading is not allowed. It is important to have different names of functions and Methods.
  • Go is ranked on the 8th but Java is ranked 18th on the list of best programming languages. 
  • The Go API is entirely handled by Google.
  • Both have a distinctive take on polymorphism. Java supports polymorphism by default. On the other hand, Go does not.
  • Java API is controlled by an open community process.
  • Namespace in Java doesn’t tell the location of the source file.
  • Java only supports source files that have a public class inside it.
  • Go is basically compiled to machine code.
  • Although, Go gives lightweight thread routines that run on Operating system threads.
  • Java doesn’t allow operator overloading, which makes it more trouble-free.
  • Also, Java helps omission checks to trap and handle errors.
  • Go gives built-in data types like slices and maps, some generic functions like append and copy, etc.
  • Java has no fundamental unsigned numeric types. This is what makes Java irrelevant for programming of a low level.

Comparison table for Go vs Java 

Comparison Between Java vs GoGoJava
LanguageGo is an independent programming language and has two compilers such as go and GCC go.Java is an independent language.
Expression Syntax

The syntax on Go is defined by utilizing of Extended Backus-Naur Form (EBNF). Syntax the identical everywhere – independent of a compiler or an IDE.
RoutingFor routing configuration Go uses HTTP protocol For routing configuration Java Uses Akka.routing.ScatterGatherFirstCompletedRouter and Akka.routing.ConsistentHashingRouter
SpeedNormally faster than JavaIt is slower than Go
Mobile SupportThe Go mobile sub repository incorporates mobile support for mobile platforms like Android and iOS and gives tools for developing mobile apps.It depends on the device manufacturers.
ArchitectureIt doesn’t give any VM such as Java JVM. This language only compiles to metal like c/c++.Also, It connects both the compilation and interpretation procedure. Bytecode is represented by JVM. Machine code created by Java Virtual machine and executed by the system in which Java program runs.
Dependency InjectionUses dependency injectionUses dependency injection and provides modification
StructureBut, it Can be managed easilyEasier to maintain, Better structure,  maintain extensive applications and user- friendly.


For this reason, Go was designed by engineers of Google and was really designed to give fast advancements and reactions. Much more useful for present-day processing systems, and a much clear human-unmistakable code than several frameworks languages like C++ or C. Java allows the developers to run the identical code on different platforms.

So, applications on the basis of Java normally compile to bytecode. In this article, we have given all the essential pieces of information regarding Go vs Java difference and comparison. We have also given the pros of both the programming languages for your better understanding.

As a result, Our computer science experts are available for you. Accordingly, you can get Java programming help at very best price
