Question

I have an interesting string I want to properly break up into a string array. This string is as follows.

String test="?[32,120],x1y1,[object pieceP1],null]";

Now I have this regular expression to attack this.

String delims = "[?,\\[\\]]";

Now the results of splitting it using this code

String[] tokens = mapString.split(delims);

yields this result

–>
–>
32
120
–>
x1y1
–>
object pieceP1
–>
null

where the arrows are the empty lines.

How can I modify this regular expression so that there are no empty lines?

Thank you greatly in advance.

Answer 1

String delims = "[?,\\[\\]]+"; // []+

see the Greedy quantifiers part in Summary of regular-expression constructs of Pattern

but the leading empty element is still there.
