Answer 1

First you have to define the type you wanna insert to the arraylist like this:
ArrayList <Integer> list = new ArrayList <Integer>(Here you can choose the size, but you can leave it empty);
Here is the fixed code and look at the comment I added:

Answer 3

There is nothing wrong with your code if you want to remove any number that is less than 3 or greater than 6 and || Will work for that, but if you are using && operator then there is no need to use iterator because your condition is going to be false always and hence nothing will be removed from the list
