Java string splitting quirks
Raw
JavaStringSplittingQuirks.groovy
// Splitting an empty string returns an array with an empty string
assert "".split(";") == [""]
// Splitting a string consisting of just the delimiter returns an empty array
assert ";".split(";") == []
// Trailing delimiters are ignored
assert "1;;2;;".split(";") == ["1", "", "2"]
// ... but the behavior becomes consistent with a -1 extra argument
assert ";".split(";", -1) == ["", ""]
assert "1;;2;;".split(";", -1) == ["1", "", "2", "", ""]
