import java.util.Arrays;
import java.util.Random;

public class Main {
  private static double[] anArray;

  public static void main(String args[]) {
    anArray = new double[10];
    Random rand = new Random();
    for (int i = 0; i < 10; i++) {
      anArray[i] = rand.nextInt();
    }
    System.out.println(Arrays.toString(anArray));
  }

}
