Split Java String by New Line

Question

I\'m trying to split text in a JTextArea using a regex to split the String by \\n However, this does not work and I also tried by \\r\\n|\\r|

Answer 1

As an alternative to the previous answers, guava's Splitter API can be used if other operations are to be applied to the resulting lines, like trimming lines or filtering empty lines :

import com.google.common.base.Splitter;

Iterable split = Splitter.onPattern("\r?\n").trimResults().omitEmptyStrings().split(docStr);

Note that the result is an Iterable and not an array.
