从列表中删除值时，Iterator.remove() 不起作用

Question

I have a list let say car and i have to remove the values from the list based on certain condition so if the value is null then i have to remove the value from the list. My code looks like :

List<CarDTO> carList //list 
Iterator<CarDTO> itr = carList.iterator();
while (itr.hasNext())
{
    CarDTO car = itr.next();
    String carText = car.getCarText();
    carText = replaceCarTextWithCompanyName(carText, readData);
    if (CommonUtils.isEmpty(carText))
    {
        itr.remove();   //this is not working, values are still getting displayed
    }
    else
    {
        car.setCarText(carText);
    }
}

Answer 1

Here you have an example:

List<String> names = new ArrayList<>(Arrays.asList("Bob", "Don", null, "Mark", null, "John"));
    
    List<String> newNames = names.stream()
        .filter(Objects::nonNull)
        .collect(Collectors.toList())
        ;
    
    newNames.forEach(System.out::println);
