How would I make this method print the parameter number of times a random integer. This is the method, but it currently only prints a random number.

This is the method, but it currently only prints a random number.

What I have tried:

<pre lang="Java"><pre><pre lang="Java">/**
     * Print multiple random intergers values using System.out.println.
     * @param howMany How many random values to print.
     */
    public void printMutliRandom(int howMany){
        Random rand = new Random();
        System.out.println(rand.nextInt(howMany));
    }

If you want to print a random number N times, you need to loop round N times, printing a single random value each time ...

And don't declare the Random instance inside a method: it is initialised from the system clock when it is created, so with modern processors it's quite likely to generate the same sequence repeatedly if you call the method several times. Declare and initialize it at class level instead.
