Android Question String Functions - Split Behavior

ansoUzr · Aug 5, 2016

I have a string s = "a,,,". If I use ... SF.Split(s,",") the length of the returned list is 2. If I change to "s= a, , ," the returned length is 3. I would have thought both would have returned a length of 4. Am I missing something? (For comparison: Visual Basic Split Function returns 4.)

Trailing empty matches are removed (see the documentation).

B4X:

Dim s() As String = Regex.Split(",","a,,,") '1
Log(s.Length)
Dim s() As String = Regex.Split(",","a,,, ") '4
Log(s.Length)

Thanks. I should have caught that.
