How do you remove all certain elements or characters from an ArrayList?
Let's say I have a scanner object like
Scanner keyboard = new Scanner(System.in);
String userInput = keyboard.nextLine();
And the user inputs something like
Bubblesort.=
If I wanted to save the characters of the String variable to an ArrayList, I'd use a char ArrayList and then load the characters in using a for loop like so
ArrayList<Character> stringArrayList = new ArrayList<Character>();
for (int i = 0; i < userInput.length(); i++) {
stringArrayList.add(userInput.charAt(i));
}
My question is, how do I remove all the characters which aren't letters. Like '.', and '=' so that the ArrayList contains only the word "Bubblesort"?
