Java myString.replaceAll（regex，"；）未按预期工作

正如我在这里被问到的。我想删除

字符串中任何开始
[
和结束
]
之间的所有
正则表达式

我使用的答案是
myString=myString.replaceAll（“\\[（[\\w\\\%\\@]+）\\]”，”）。由@cuong hoang提供。现在，该方法可以很好地处理大多数
Srtring
，但是该
字符串出现了一些问题：

我使用方法
myString=myString.replaceAll（“\\[（[\\w\\%\\@]+）\\]”得到的输出字符串
上的code>与相同
字符串
完全相同

当您得到
[blabla]
时，可能使用该
正则表达式的方法工作不好，然后我在这里得到了另一个
[blablabla2]
。
您可以使用该
替换所有
字符类：

myString = myString.replaceAll("\\[[^\\]]*\\]", "");

正则表达式分解：

\\[      # match a literal [
[^\\]]*  # match 0 or more of any character that is not ]
\\]      # match a literal ]

您可以将此
replaceAll
用于否定字符类：

myString = myString.replaceAll("\\[[^\\]]*\\]", "");

正则表达式分解：

\\[      # match a literal [
[^\\]]*  # match 0 or more of any character that is not ]
\\]      # match a literal ]

试试：
myString=myString.replaceAll（“\\[^\\]]*\\\]”，“”）
@anubhava你的意思是
myString=myString.replaceAll（“\\[[^\]]*\\]”，”）？@anubhava是的，这很有效。你能把它作为一个答案贴出来，解释一下方法函数吗？谢谢。请尝试：
myString=myString.replaceAll（“\\[^\]]*\\\]”，“”）
