Regular expression in Java for splitting a String

Question

What is the regular expression in Java for splitting a String like: [space]0[space] (space followed by zero followed by space)?

eg

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5

splits as:

123456789101112131415 

and

12345

Answer 1

String[] split = string.split(" 0 ");

Unless you meant "any whitespace" when you said space. Or "a sequence of one or more space characters".

Answer 2

If you don't mind having some extra spaces: \\b0\\b .

If you do want to remove spaces, this should work for the start and end zeros as well: \\s?\\b0\\b\\s?

Answer 3

这应该有效：

string.split("\\s0\\s");
