USE JAVA.
Write a program that produces random permutations of the numbers 1 to 10. (Note: 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 smarter 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 permutationArrayList. Repeat ten times.
Instructions:
Turn in your source code and a printed run output.
The run output will consist of 10 lists of random permutations of the number 1 to 10. Example output is shown below:
