Hi, can anybody can give me a hint/help. Trying to figure out my mistake. When trying only this block of code "two sets, iterate set,, set2.add, set.removeAll(set2)" works fine...
package com.codegym.task.task08.task0814;
import java.util.*;
import java.util.HashSet;
import java.util.Set;
/*
Greater than 10? You're not a good fit for us
*/
public class Solution {
public static HashSet<Integer> createSet() {
HashSet<Integer> set = new HashSet<Integer>();
for(int i=0; i<20; i++) {
set.add(i);
}
return set;
}
public static HashSet<Integer> removeAllNumbersGreaterThan10(HashSet<Integer> set) {
HashSet<Integer> set2 = new HashSet<Integer>();
Iterator<Integer> i = set.iterator();
while (i.hasNext()) {
if(i.next()>10) set2.add(i.next());
}
set.removeAll(set2);
return set;
}
public static void main(String[] args) {
}
}
