Question

Let’s say I have this String –

string = "AEIOU";

and I wanted to convert it to an ArrayList<String>, where each character is it’s own individual String within the ArrayList<String>

[A, E, I, O, U]

EDIT: I do NOT want to convert to ArrayList<Character> (yes, that’s very straightforward and I do pay attention in class), but I DO want to convert to an ArrayList<String>.

How would I do that?

Answer 1

transform the String into a char array,

char[] cArray = "AEIOU".toCharArray();

and while you iterate over the array, transform each char into a String, and then add it to the list,

List<String> list = new ArrayList<String>(cArray.length);

for(char c : cArray){
    list.add(String.valueOf(c));
}
