Splitting on multiple delimiters but keep the delimiters on the same string

Question

I want help with regular expressions to solve the following problem:

I have a string such as \"1£23$456$£$\"

when I split on it I want the output in my strin

Answer 1

Use a look behind, which is non-consuming:

String[] parts = str.split("(?<=\\D)");

That's all there is to it. The regex means to split "just after every non-digit", which seems to be exactly your intention.

Some test code:

String str = "1£23$456$£$";
String[] parts = str.split("(?<=\\D)");
System.out.println( Arrays.toString( parts));

Output:

[1£, 23$, 456$, £, $]
