Java RegEX To Split and Reverse String
I have a Java String "test/this/string" that I want
to reverse to "string/this/test" using a
regular expression or the most efficient Java algorithm. The way I know is to
use the split method, loop over the array and rebuild the string manually. The
number of "/" can vary and doesn't occur a fixed number of times. Any
ideas?
Hey Tanuja!
Here's my take:
(?<=/) is a zero-length matching regex that matches if the previous character is a /.
(?=/) is a zero-length matching regex that matches if the next character is a /.
So (?=/)|(?<=/) matches right before and after each /, thus the split splits the string
into"test", "/", "this", "/", "string".
