Generate auto increment number by using Java

Question

I am trying to generate unique auto increment id which will started from 0 . I found something for doing this using below code:

private static final AtomicInteger count = new AtomicInteger(0);   
uniqueID = count.incrementAndGet(); 

I can create auto increment ID by manually :

For example :

int i = 0; // Obviously I will declare this variable as global
++i;

In this way I can manage to do this. But I don't want to do this manually. I am finding some java method which will take of all this stuff.

And I found below code :

private static final AtomicInteger count = new AtomicInteger(0);   
uniqueID = count.incrementAndGet(); 

Now my question is, Is this the right way to generate unique ID? Or, is there any other better solution?

Answer 1

如果它应该仅在单个进程中是唯一的，那么是的，您可以使用 AtomicInteger。
