Use regular expressions to determine whether there are duplicate characters in a string

This article introduces how to use Java regular expressions to determine whether a fixed-length string contains duplicate characters. The core idea is to use reverse matching, that is, to find a string containing duplicate characters, and then determine whether the target string does not match the expression. The article will provide detailed regular expressions and provide Java code examples to help readers understand and apply the method.
