如何从字符串创建String []数组? [英] How to create a String[] array from a String?

问题描述

我在变量 coords 上有一个String，它具有String数组的值，但它不是数组(toString的结果).

I have a String on the variable coords which has the value of a String array, but it is not an array (outcome of toString).

String coords = "[[126,224],[255,232],[270,332],[106,444]]";

如何从此字符串创建字符串数组?数组没有#valueOf(据我所知)，并且您不能轻易拆分字符.

How can you create a String array from this String? An array doesn't have a #valueOf (as far as I know) and you can't easily split the characters.

我正在寻找一个String数组，其中包含四个String作为自己的条目.例如."126,224"，"255,322" ..

I am looking for a String array which contains the four Strings as their own entries. E.g. "126,224", "255,322"..

推荐答案

最简单的方法之一是:

String[] array = coords.replaceAll("\\[\\[", "").replaceAll("\\]\\]", "").split("\\],\\[");

上面的代码将所有 [[[和]] 替换为一个空字符，然后用]，[分割.

The above code replaces all [[ and ]] with an empty character and then split by ],[.
