Java String split is not working

Question

Java Experts ,

Please look into the below split command code and let me know why last two nulls are not captured.

String test = \"1,O1,,,,0.0000,0.0000,         


        

Answer 1

It behaves as specified in the javadoc:

This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

If you want to keep the trailing blank strings, you can use the 2 argument split method with a negative limit:

String[] splittest = test.split(",", -1);

If the limit is non-positive then the pattern will be applied as many times as possible and the array can have any length.
