Splitting a string using Regex in Java

Question

Would anyone be able to assist me with some regex.

I want to split the following string into a number, string number

\"810LN15\"

1 metho

Answer 1

In Java, as in most regex flavors (Python being a notable exception), the split() regex isn't required to consume any characters when it finds a match. Here I've used lookaheads and lookbehinds to match any position that has a digit one side of it and a non-digit on the other:

String source = "810LN15";
String[] parts = source.split("(?<=\\d)(?=\\D)|(?<=\\D)(?=\\d)");
System.out.println(Arrays.toString(parts));

output:

[810, LN, 15]
