How to generate cryptographically random numbers?

How can I generate a certain amount of random numbers in java.?

• I'm trying to write a program where the user enters a number and the program will generate that many random numbers. For example the user enters 5 and the program shows 1,9,5,7,6. I have so far: Scanner input = new Scanner(System.in); System.out.print("Enter n: "); int n = input.nextInt(); *****This is where I'm stuck because I'm not sure how to use whatever number the user enters and have the program generate that many random numbers. If you could help me out that would be great and if you could explain I would appreciate it. There's another part to this program but I'm pretty sure I know how to write it.

• Answer:

  use a "for" loop. in each loop, generate a random number, and display it to the screen. gl.
