Why golang is preferred over java for concurrency.

First of all we should have a basic knowledge of what concurrency is and how it is achieved. So Concurrency is running multiple tasks at the same time there are two terms parallelism and concurrency which are not same both are different parallelism is doing multiple task at same time but in concurrency time can overlap between two tasks is done but in parallelism both task will start at same time eg: multicore processor. 

 

The multicore processor machines are very fast for computation. It gives you the result in seconds  because at the backend multiple cpus are running at the same time parallely. Different programming languages use this concept of concurrency in their own way like threading,process,goroutines etc. But we will talk about java and golang, how they handle concurrency and which language is more effective for concurrency.

 

When we talk about JAVA then it uses threads for performing concurrency but it runs autonomous threads which are more expensive to create and manage also and java is designed with very little concurrency in mind and it is also not memory efficient because the size of one thread is up to mb. Java runs on a virtual machine JVM which also takes a lot of time to compile the code and it is not as much faster as golang.

 

On the other hand Golang has been designed with concurrency and parallelism in mind and it is a very fast language because it does not require any virtual device to compile or it also compiles the whole code into a single binary file which is very small in size also. Go uses goroutines to handle concurrency and parallelism and the threads are very lightweight and also very small in size in kbs. The synchronization in golang is also handled by the channels which are used for communication of goroutines. You only need to create channels and pass those channels to the goroutines to send messages safely without any deadlock. The deadlock is also managed by goroutines using channels so it is very cheap and easy to use goroutine for multithreading.

Conclusion:- After this long discussion I will advise you to use golang for your project if you are working on a project where concurrency matters most because it is easy to maintain and also very cheap and lightweight threads in compare to java.
