I'm looking to split a sentence into an array of words separated by a comma in Java.
That is, I want a sentence like:
"The dog jumped"
"high over the"
to become
"The,dog,jumped"
"high,over,the"
I can't seem to get it to pick up the space and insert with a comma using the .split(",") method but that doesn't appear to work, the result is still the original. Ideas? Thanks!
The easiest way would be to use String#replaceAll(), replacing spaces with ,:
String s = "The dog jumped";
String sWithComma = s.replaceAll(" ", ",");
If you want to allow for cases more complicated than the sample you posted (multiple spaces, tabs etc.), you should use this other answer.
Using regex for one or more space and replacing it with "," like this-
"The dog jumped".replaceAll("\\s+", ",")
Many ways to do this. I would look at using strtok for a task like this, or maybe the apache commons StringUtils package, or replaceAll. I won't give you the exact code,because this smells like an assignment :)
