I want to generate random number between two numbers which are multiples of 10.
For example, between 100 and 500, I want to generate a uniform distribution of 110, 120 ... 490, 500. 

I think it is better to use Random.nextInt() as per [THIS](https://stackoverflow.com/questions/738629/math-random-versus-random-nextintint) post. But not sure how to do that.
