When I try to remove a int
from arrayList
it is simply an error.
Code:
ArrayList<Integer> colors = new ArrayList<>();
colors.add(Color.rgb(119, 103, 141)); colors.add(Color.rgb(33, 10, 208)); colors.add(Color.rgb(203, 100 ,180));
colors.add(Color.rgb(249, 0 ,193)); colors.add(Color.rgb(74, 169, 94)); colors.add(Color.rgb(25, 236, 70));
colors.add(Color.rgb(235, 213, 92)); colors.add(Color.rgb(242, 206, 9)); colors.add(Color.rgb(68, 243, 220));
int teste = colors.get(3);
colors.remove(teste);
Error:
