So let's say I got 2 numbers, 65 and 75, is there any way so Greenfoot only pick between 65 or 75? Thanks!

Randomly pick specific number
You randomly choose the amount of numbers you want to be picked from, then add the lowest number in your range.
Greenfoot.getRandomNumber(10) + 65;
More generally, you could have something like this:
int[] nums = new int[] { 65, 75 }; // any set of values
int choice = nums[Greenfoot.getRandomNumber(nums.length)];But, if you use an array and you want a random number chosen with the range of 65 to 75, then you will need to set each int variable that's part of the array to each of the numbers you want chosen from.
It can be done with a loop but you still need an initialization for each number you want to be able to choose from (instead of getting one variable which is randomly initialized with a number in your range).
int[] nums = new int[] {65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75};sorry if I confuse you, but what I wanted actually is Greenfoot randomly pick from set of my own specific number (in this case, what I wanted is to pick only 65 or 75 and not any number between that)
and in this case danpost's code fulfills what I needed ^.^
once again, thanks for the help!
