Remove Only One Item from a List (Android)
Clash Royale CLAN TAG#URR8PPPRemove Only One Item from a List (Android)
I have a list: (x, y, y,z)
(x, y, y,z)
I have another list: (x, y)
(x, y)
You want to remove the items from the 1st list that belong also in the 2nd list.
Ex: I want the result to be (y,z)
(y,z)
How do I do this?
EDIT: If I use removeAll. The example list returns (z)
Does order matter? For example, if the second list was (y, x) would you want the same outcome?

You can use remove all
List<String> one = new ArrayList<String>();
one.add("x");
one.add("y");
one.add("y");
one.add("z");
List<String> two = new ArrayList<String>();
two.add("x");
two.add("y");
one.removeAll(two);
System.out.println(one);
If I removeAll. The example list returns (z)
