Question

I am getting this string from a program

[user1, user2]

I need it to be splitted as

String1 = user1
String2 = user2

Answer 1

You could do this to safely remove any brackets or spaces before splitting on commas:

String input = "[user1, user2]";
String[] strings = input.replaceAll("\\[|\\]| ", "").split(",");
// strings[0] will have "user1"
// strings[1] will have "user2"
