I need to split a string. Simple:

Code:

String s = "Hello-world";
String str[] = new String[2];
str = s.split("-");

But, what happens when your string is user input?

Code:

String s = JOptionPane.showInputDialog(null, "text will be split at the spaces");
//they enter "Hello-world,-my-name-is-Susie"
String str[] = new String[2];
str = s.split("-");

This throws an out of bounds exception at 2.
What about ArrayList()?

Code:

//with the same user input
ArrayList<String> strings = new ArrayList<String>();
strings.add(s.split("-"));

The thing is that (for an ArrayList), there is no such thing as that last bit of code. What code that is real and does the job of strings.add(s.split("-")); for an ArrayList?
