How to take multiple lines of input

Question

If I copy and paste into a program It only takes the first line for instance I copy a few blocks from Microsoft Excel and Paste it pastes the codes like this:

72LYY-785B9-0WQD9
88CXK-4E8BB-TA2GD
JLEIZ-0KYKP-PY2E4
LV5TL-A6CLB-P59GX

My program only takes 72LYY-785B9-0WQD9 , but I want the scanner to take all until it is empty.

I am using

String userData = takeInput.nextLine();

I put it into a String and then turn it into an array of chars.
Any help?

Did you try any other approach?

Scanner stdin = new Scanner(new BufferedInputStream(System.in));
while (stdin.hasNext()) {
  System.out.println(stdin.nextLine());
}
