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

brackets is not a part of your array list, since as you've mentioned it's Integer typed

ArrayList

when you print errors using

System.out.println(errors);

it's just formatting your data, just iterate over the array and print each value separately
