(java beginner here)
I am following this [Random shuffling of an array](https://stackoverflow.com/questions/1519736/random-shuffling-of-an-array) 
but what i want to do is instead of randomly changing elements in an array then using it in my method. I want to make sure the order of the changing list is going from [1]..[2]..[3].....
(basically increasing)
My ultimate goal is to have a table of numbers 

int[] a = {1,2,3,4,5,6} then it in my method 

```
static void shuffleArray(double[] solutionArray)
{
    Random rnd = new Random();
    for (int i = solutionArray.length - 1; i > 0; i++)
    {
      int index = rnd.nextInt(i + 1);
      int value = 0;
     // int charValue = value.digit(0);
      String next = String.valueOf( (double) (value + 1));
      System.out.println(next);
      // Simple swap
      double a = solutionArray[index];
      solutionArray[index] = solutionArray[i];
      solutionArray[i] = a;
    }

  }

public static void main(String[] args)
{
  double[] solutionArray = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7};
  double[] solution = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7};
  shuffleArray(solutionArray);
  shuffleArray(solution);

  for (int i = 0; i < 7; i++)
  {
      position.setspeed(solutionArray[0]);
  }
}

```

but when i set it or use it in a method i want it to go from 1 to 6 instead of randomly choosing an element or from the link shuffling the element.
