Answer 1

package javaapplication1;

import java.util.Random;

public class Example {
    
    public static final int N = 20;
    
    public static void main(String[] args) {
               
        Random rand = new Random(); 

        for (int i = 0; i < N; i++) 
            System.out.println(rand.nextInt(90000000) + 10000000);

        // min = 0 + 10000000 
        // max = 9000000 - 1 + 1000000 = 9999999
