Something like this should work:

String[] lines = text.split("\\s*\\n+\\s*");

Or better if you're using Java 8 (per Pshemo), use "\\R+"

This will skip over multiple blank lines, or lines filled with white space, and should trim leading and ending whitespace as well.

Or to split on one or more line separators since Java 8 we can use `"\\R+"` - http://stackoverflow.com/a/31060125/1393766 – Pshemo Feb 28 '16 at 15:03

No problem. Added link in earlier comment to one of my answers which explains `\R` a little. – Pshemo Feb 28 '16 at 15:06

String[] lines = jtextFieldName_you_used.getText().split("\\n");

It is to store textarea elements to array.Hope you find this helpful.

Try this.

String str = abc.getText();
for (String retval: str.split(" ")){ System.out.println(retval); }

If i understood your task right:

final String[] lines = data.split("\\n");
final String results[] = new String[lines.length];
int offset = 0;

for (String line : lines) {
   results[offset] = line.split("\\s")[1];
   offset++;
}

results:

test1111
blankline
test222

p.s: without data checks
