Jun 3, 2016 · You could try to split on (?<=\D)(?=\d)|(?<=\d)(?=\D), like: str.split("(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)"); It matches positions between a number and not-a-number (in any order). (?<=\D)(?=\d) - matches a position between a non-digit (\D) and a digit (\d) (?<=\d)(?=\D) - matches a position between a digit and a non-digit.

May 28, 2013 · You could try to split on a regular expression like (?<=\D)(?=\d). Try this one: will output. You might parse the digit String to Integer with Integer.parseInt(part[1]).

Jan 8, 2024 · In this article, we’ve explored regex-based (split ()) and non-regex-based (parseString ()) approaches to breaking an input string into a string array or list containing digit elements and non-digit string elements in the original order.

Apr 11, 2025 · The String split () method in Java is used to split a string into an array of substrings based on matches of the given regular expression or specified delimiter.

The split() method splits a string into an array of substrings using a regular expression as the separator. If a limit is specified, the returned array will not be longer than the limit.

In this tutorial, we covered various methods to split strings into letters and digits in Java, from simple regex replacements to more advanced stream techniques.

In Java, splitting a string between letters and digits can be achieved using regular expressions with the `String.split ()` method. This technique allows for flexible parsing of any input string that contains a combination of letters and numbers.

In Java, you can split a string into letters and numbers using regular expressions. By utilizing the split () method from the String class along with a regex pattern, we can effectively separate the components of the string.
