String.split() is not working

Question

I have to split a string in this way :

String s = "00JS1B4BJG2C2G3S6C6S5CHG1C4CKS3C1G5S6B3G7BHB7G6G5B";
String[] result = s.substring(2).split("(?<=\\G.{2})");

The correct result is:

["JS","1B","4B","JG","2C","2G","3S","6C","6S","5C","HG","1C","4C","KS","3C","1G","5S","6B","3G","7B","HB","7G","6G","5B"]

And this is working in Java, but in Android it returns:

["JS", "1B4BJG2C2G3S6C6S5CHG1C4CKS3C1G5S6B3G7BHB7G6G5B"]

...as I can see when debugging:

Any ideas?

Answer 1

Try using this expression ( G.. instead of G.{2} ):

s.split("(?<=\\G..)")

Or you can appending space every two step ( using as delimiter ) :

s = s.replaceAll("..(?!$)", "$0 ");
s.split(" ");
