printing method class randTest (int n)

I am having trouble printing out the method randTest (int n) as errors keep appearing. I want to print this method in the main as i want to print the results in a clear tabular form. The method must stay static void. This is my code below:

public class RandNumGenerator {

    public static int RandInt(){
        double n = Math.random()*10;
        return (int) n;
        }

    public static void randTest(int n){
        int [] counts = new int [10];

        for(int i=0;i<n;i++){
            counts[i] = RandInt();
            System.out.println(counts[i]);
            } 
        }

    public static void main(String[] args) {
        System.out.println(RandInt());
        System.out.println(randTest());
    }
}
