I'm trying to find a way to split a String in Java without ignoring the spaces. After searching I've found a way to do it in python :
re.split(r"(\s+)", "This is the string I want to split")
would result in:
['This', ' ', 'is', ' ', 'the', ' ', 'string', ' ', 'I', ' ', 'want', ' ', 'to', ' ', 'split']
How can this be done in java?
Yep, you need to use lookarounds.
string.split("(?<=\\s+)|(?=\\s+)");
(?<=\\s+) Matches the boundary which exists after one or more spaces.
| OR
(?=\\s+) Matches the boundary which exits before one or more spaces.
Splitting according to the matched boundary will give you the desired output.
Example:
String s = "This is the string I want to split";
String[] parts = s.split("(?<=\\s+)|(?=\\s+)");
System.out.println(Arrays.toString(parts));
Output:
[This, , is, , the, , string, , I, , want, , to, , split]
