How to remove the brackets [ ] from ArrayList#toString()?

Question

I have created an Array List in Java that looks something like this:

 public static ArrayList error = new ArrayList<>();

for (int x= 1         


        

Answer 1

There are not brackets inside your list. This is just the way Java prints a list by default.

If you want to print the content of your list, you can something like this

for (Integer error : errors) {
    System.out.format("%d ", error);
}
