Insert whitespace between two characters in a string if a condition is met

Question

I have a string in the following format:

"0,0,0,0|1,0,0,0,0|1,1,0,1"

but there can be numbers missing, like this:

"0,0,,|1,,,1,0|,1,1,1"

I want to extract the data from each of those blocks between the '|' character. Getting to the individual blocks is fairly easy:

"0,0,,|1,,,1,0|,1,1,1".split("|");

now when I try to split the blocks, I lose information:

"0,0,,".split(",");

becomes an array of two elements ["0","0"]

",1,1,1".split(",");

becomes ["","1","1","1"], exactly what I want. An array of four elements, one of which is an empty string

How can I split the array, without losing information, i.e. the resulting array being one of length 4 in the case of "0,0,,".split(",")? An idea of mine is in the title, but I don't know how to implement it

EDIT: I tried doing this before splitting by ","

someVar= "0,0,,".replaceAll(",,", ", ,");

which works fine between two commas (as expected), but it doesn't work for the last missing value:

splitting someVar will give us ["0","0"," "]

if the there is no number do you assume it to be zero, so for your example you want 0,0,, to become 0,0,0,0? — RAZ_Muh_Taz, Jan 20 '17 at 00:06

@JorgeCampos I had not found the post you linked. It might really be a duplicate. I'll try out the solution there — user6454491, Jan 20 '17 at 00:10
Have you read the question I marked yours as a duplicate? No need for a replace. Just use the second parameter of split method. As the docs mentions it. — Jorge Campos, Jan 20 '17 at 00:12

String[] result = text.split("\|", any negative value);

Use this. This will fix your issue.
