Java（Regex？）在数字/字母组合之间拆分字符串 [英] Java (Regex?) split string between number/letter combination

问题描述

我一直在查看Google搜索结果的页面和页面，但没有找到任何可以帮助我的内容。

I've been looking through pages and pages of Google results but haven't come across anything that could help me.

我要做的是拆分像 Bananas22Apples496Pears3 这样的字符串，并将其分解为某种可读格式。由于 String.split（）无法做到这一点，我想知道是否有人可以指向一个可以实现此目的的正则表达式片段。

What I'm trying to do is split a string like Bananas22Apples496Pears3, and break it down into some kind of readable format. Since String.split() cannot do this, I was wondering if anyone could point me to a regex snippet that could accomplish this.

扩展一下：为简单起见，上面的字符串将被拆分为（ String [] ：

Expanding a bit: the above string would be split into (String[] for simplicity's sake):

{"Bananas:22", "Apples:496", "Pears:3"}

推荐答案

试试这个

String s = "Bananas22Apples496Pears3";

String[] res = s.replaceAll("(?<=\\p{L})(?=\\d)", ":").split("(?<=\\d)(?=\\p{L})");
    for (String t : res) {
        System.out.println(t);
    }

第一步是用：替换空字符串，左边是带有 lookbehind断言 的字母（？ < = \\\\ {L}），右边是一个数字， lookahead断言 （？= \\d）。

The first step would be to replace the empty string with a ":", when on the left is a letter with the lookbehind assertion (?<=\\p{L}) and on the right is a digit, with the lookahead assertion (?=\\d).

然后拆分结果，左边是数字，右边是字母。

Then split the result, when on the left is a digit and on the right is a letter.

\\\\ {L} 是 Unicode属性，匹配每种语言的每个字母。

\\p{L} is a Unicode property that matches every letter in every language.
