Hi is there a way by which i can generate a random no between a specific range.
I read that the class allows you to generate no between 0-n ie.(0-65) what if i want to generate random nos between 55-65 ??

First generate a random number and then map it to your range. If you want between 10 and 50
Random rand = new Random();
int min=10,max=50;
int num = rand.nextInt(max-min) + min;

Hope this helps!

Nice touch, using max and min rather than number literals. You do realise that formula will never produce 50 as a result, only 49?

Yes. And if you want to include 50 change the code to this..
int num = rand.nextInt(max-min+1) + min;

A lot of people don’t realise that. If you need 50, you have to include + 1.
 
Don't get me started about those stupid light bulbs.
