I'm having trouble figuring out what to do and how to do.. could someone explain to me what I need to do in order to work?

THIS IS WHAT I NEED TO DO:

Professor Snoop wants a program that will randomly generate 10 unique random numbers. Your job is to write a program that produces random permutations of the numbers 1 to 10. “Permutation” is a mathematical name for an arrangement. For example, there are six permutations of the numbers 1,2,3: 123, 132, 231, 213, 312, and 321.

To generate a random permutation, you need to fill an ArrayList with the numbers 1 to 10 so that no two entries of the array have the same contents.

You could do it by brute force, by calling Random.nextInt ( ) until it produces a value that is not yet in the array. Instead, you should implement a smart method.

Make a second ArrayList and fill it with the numbers 1 to 10.

Then pick one of those at random, remove it, and append it to the permutation ArrayList. Repeat ten times.

Implement a class PermutationGene rator with the following method:

ArrayList nextPermutation

The output will consist of 10 lists of random permutations of the numbers 1 through 10.

Example output is shown below:

Random Permutation List Generator

List 1: 4 6 8 1 9 7 10 5 3 2

List 2: 6 8 1 7 3 4 9 10 5 2

List 3: 2 4 9 6 8 1 10 5 7 3

List 4: 8 5 4 3 2 9 6 7 1 10

List 5: 10 3 2 6 8 9 5 7 4 1

List 6: 9 10 3 2 1 5 6 8 4 7

List 7: 3 8 5 9 4 2 10 1 6 7

List 8: 3 2 4 5 7 6 9 8 10 1

List 9: 4 1 5 10 8 3 6 2 7 9

List 10: 3 5 2 4 1 7 9 6 8 10

THIS IS WHAT I HAVE SO FAR:

- String[] randomNum = {"", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10"};
- int i = 10;
- int n = 10;
- /*creates an array for the randomly selected numbers*/
- }
- private ArrayList<Integer>permutation = new ArrayList<Integer>();
- {
- String Numbers = randomNum.Random.nextInt();
- }
- public int PermutationGenerator();
- {
- for(int i = 0; i < 10; i++)
- {
- nums.add(i + 1);
- }
- Random generator = new Random();
- {
- for (int n = 0; n < 10; n++)
- int n = randomNum.nextInt(nums.size());
- permutation.add(nums.get(d));
- }
- }
- }

Thank You.
