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

The brackets you see are just an automatic way to display a List in JAVA (when using System.out.println(list); for example.

If you do not want them to show when showing it, you can create a custom method :

public void showList(List listInt)
{
    for(int el : listInt)
    {
        System.out.print(el + ", ");
    }
}

Then adjust this code to show this according to your liking !
