Can somebody explaim why below code generates sets of different size each time when I populate this set with random numbers?
public static HashSet<Integer> createSet() {
// write your code here
HashSet<Integer> numbers = new HashSet<>();
Random randomNumbers = new Random();
for(int i=0; i<20; i++){
numbers.add(randomNumbers.nextInt(100));
}
return numbers;

import java.util.HashSet;
import java.util.Random;
import java.util.Set;
/*
Greater than 10? You're not a good fit for us
*/
public class Solution {
public static HashSet<Integer> createSet() {
// write your code here
HashSet<Integer> numbers = new HashSet<>();
Random randomNumbers = new Random();
for(int i=0; i<20; i++){
numbers.add(randomNumbers.nextInt(100));
}
return numbers;
}
public static HashSet<Integer> removeAllNumbersGreaterThan10(HashSet<Integer> set) {
// write your code here
set.removeIf(n -> (n>10));
return set;
}
public static void main(String[] args) {
}
}
