How toMake Math.random generate number between 1 and 1000? [duplicate]

So I'm trying to figure out how to print out a random number between 1 to 1000.

I tried:

 double a = 1+ (Math.random()*1000);
            System.out.println(a);

But when I try this i get numbers with a bunch of decimals. I do not want any decimals. Anyone can help? I want to get a value like 50 or 289 or 294. I do not want to get a number like 234.5670242 or 394.220345. Help if you can. will appreciate it. Thank you.
