Question

I’m printing ArrayLists.toString() to a file and this is the result

[FirstLine
, SecondLine
, ThirdLine
]

I would like to remove the [ ] and , from my output.
Should I use a for loop to print the content of my ArrayList or is there an alternative way ?

thanks

If you don’t want to use third-party libraries, you can just use StringBuilder and a for-each loop.

StringBuilder sb = new StringBuilder();
for (Item item : list) {
   sb.append(item.toString());
}
String output = sb.toString();
