Add multiple items to already initialized arraylist in java

Question

I\'m googling it and can\'t seem to find the syntax. My arraylist might be populated differently based on a user setting, so I\'ve initialized it

Answer 1

If you needed to add a lot of integers it'd proabbly be easiest to use a for loop. For example, adding 28 days to a daysInFebruary array.

ArrayList daysInFebruary = new ArrayList<>();

for(int i = 1; i <= 28; i++) {
    daysInFebruary.add(i);
}
