JavaFX write the input rows of a textArea to array

Question

I need to write every single row of a textArea into an array after I click a button. However, I have no clue how to seperate the the rows of the input text so i can write them to an array. (or if this is possible at all with textareas?)

Example: Textarea: line1 line2 line3

After I lick a button, it will generate this array of Strings:

array[0]: line1
array[1]: line2
array[2]: line3

Thanks in advance.

You can do

String[] rows = textArea.getText().split("\n");

Thanks, does \n work for all operating systems? Sorry if thats a stupid question.

Yes: new lines are represented in a TextArea with \n on all platforms: assuming the user typed the text in. (If you load the text from a file, and the text file represents new lines in a different way, you may need to do some work to put the correct text into a text area, but that's a different situation.)
