"["1","2"]"转换为字符串数组

要将字符串"["1","2"]"转换为字符串数组，可以使用split方法来实现。首先，需要去掉字符串中的引号和方括号。然后，使用split方法将字符串按照逗号分割成字符数组。以下是转换的步骤：

1. 去除字符串中的引号和方括号，可以使用replace方法。将字符串中的双引号和方括号替换为空字符串。
2. 使用split方法，将字符串按照逗号分割成字符数组。

以下是示例代码：

String str = "[\"1\",\"2\"]";
str = str.replace("\"", "").replace("[", "").replace("]", "");
String[] arr = str.split(",");

这样就可以将字符串"["1","2"]"转换为字符串数组["1", "2"]。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
