Output ArrayList to String without [,] (brackets) appearing

Question

OK, so I have an ArrayList that I need to return as a String. Right now I am using this approach:

List customers = new ArrayList<>();
L         


        

Answer 1

I think the best solution to print list without brackets and without any separator( for java 8 and higher )

String.join("", YOUR_LIST);

You can alos you you own delimiter to separate printing elements.

String.join(", \n", YOUR_LIST);

example above separate each list element with comma and new line.
