Question

Given an element of an ArrayList, something like:

List<String> bunchOfLetters = new ArrayList<String>(); 

and a standard method to add some letters to it, say

public void makeUpSomeLetters(){

bunchOfLetters.add("abcdefg");

I understand that to traverse an ArrayList to inspect elements
I need to do

for(int i = 0; i<bunchOfLetters.size(); i++)
{

but I am clueless how to add whitespace to the end of it, e.g. making the end result become something like:

[abcdefg ] 

as opposed to just

[abcdefg]  

purpose: I would like to add said whitespace so that I may take a substring for said element without having the console omit characters. thank you for your time.
Cheers!

Answer 1

List<String> list = new ArrayList<String>();
list.add("ABCD");
list.set(0, list.get(0) + " ");
System.out.print(list.get(0).equals("ABCD "));

OUTPUT:

true
