Groovy String Tokenizer matching on the wrong delimiter

Question

I have a String that has values like this "inactiveCatalog%2CwrongTransaction", I want to bring this into a list breaking on the "%2C"....

String rseFiltersToRemove = "inactiveCatalog%2CwrongTransaction"
ArrayList rseFiltersToRemoveList = rseFiltersToRemove.tokenize("%2C")

I was expecting the list to have 2 elements ("inactiveCatalog" and "wrongTransaction"), but it turns out to have 3 ("inactive", "atalogItems" and "wrongTransaction").

So it thinks the "C" in "inactiveCatalog" is a delimiter.

How could this be when I set the delimiter to "%2C"?

Answer 1

The tokenize() method uses each character of a String as delimiter. So, .tokenize("%2C") splits on %, 2 and C.

Note that you do not get empty elements (that would be there in between % and and 2 and C) because tokenize() discards these empty strings when a delimiter appears twice in succession.

You need split() that takes the entire string as delimiter:

ArrayList rseFiltersToRemoveList = rseFiltersToRemove.split('%2C');
// => [inactiveCatalog, wrongTransaction]

See the online Groovy demo.
