How to split the string with slash

Question

How do I split the string using forward slash? I've tried with following code:

I have string String x="10/20//30;expecting values 10,20,30.

When I tried to split using x.split("/"); then it only splitting 10,20,"",30
When I tried to split using x.split("//"); then it only splitting 10/20,30.

Please help me to split correctly. Is there any way to skip the one slash if there are 2 slashes present?

You want to replace slashes by comma or do you want the values of ints? — TheLostMind, Oct 20 '14 at 14:37
A solution would be first splitting it using double slash: `x.split("//"):`, and then splitting each of the the results using one slash: `s[0].split("/");`. The final array of results would be: 10, 20 and 30 — Matias Cicero, Oct 20 '14 at 14:40

You could do

String[] array = x.split("/+");

I think this works, can you please tell me how it works? – user3376818 Oct 20 '14 at 14:41
It is a regular expression split where there is atleast one slash but can be more. – brso05 Oct 20 '14 at 14:43
easy enough - it uses a `+` quantifer to match one or more `/` characters – Reimeus Oct 20 '14 at 14:43
Shouldn't it be `x = x.split("[/]+");` with only one slash? Or did I misunderstand sth? – Pijotrek Oct 20 '14 at 14:47
Yep, actually character class unnecessary here :) – Reimeus Oct 20 '14 at 14:48

Because I can't comment on previous answer:

I think it has to be like

String[] s = x.split("/+");

Because otherwise it would be a conversion from String Array to String, wouldn't it?

Try to use your first approach and remove empty value from the result, in example by using the solution described here: Remove Null Value from String array in java

It's splitting fine when you use x.split("/") the problem is it is inserting a blank where the // slash is because of how the split works it will return an array of [10, 20, , 30]. Just either remove all blanks from the array or when you process just skip elements that are blank.
