Java Question

I need to show the numbers 1-10 in a random order. An example outpue while executing first time would be:

`5,4,8,7,9,1,2,3`

`7,6,5,1,2,3,4,9,8`

Will the following code print all date between ranges in random?

`Random r = new Random();`

int i1 = r.nextInt(80 - 65) + 65;

You can use the `Collections.shuffle()`

method. (more info on this SO question)

In your example:

```
List<int> numbers = new ArrayList<int>();
int min = 65;
int max = 85;
for (int i = min; i <= max; i++) {
numbers.add(i);
}
Collections.shuffle(numbers);
```
