将php正则表达式转换为java正则表达式 [英] convert php regex to java regex

问题描述

有人可以帮我将 php regex 转换为 java regex 吗?

Can somebody help me with converting a php regex to java regex?

如果您能帮助我，那就太好了，我将不胜感激，因为我在正则表达式方面不是很擅长.

It would be great and I would be appreciate you if you can help me, because I'm not so strong in regex.

$str = preg_replace ( '{(.)\1+}', '$1', $str )
$str = preg_replace ( '{[ \'-_\(\)]}', '', $str )

我如何理解 php 中的 preg_replace 函数与 java 中的 replaceAll 相同?..所以在java代码中它会是这样的.

How I understand preg_replace function in php is the same as replaceAll in java?.. So in java code it would be like this.

str = str.replaceAll("{(.)\1+}", "$1");
str = str.replaceAll("{[ \'-_\(\)]}", "");

但是这段代码不起作用，因为我怎么知道 php 中的正则表达式与 java 不同.

But this code wont be work because how I know that regex in php is different by java.

拜托，有人帮帮我！非常感谢))

Please, somebody help me! Thanks a lot))

更新

最终结果是

str = str.replaceAll("(.)\\1+", "$1");
str = str.replaceAll("[ '-_()]", "");

推荐答案

对于这个 PHP 正则表达式:

For this PHP regex:

$str = preg_replace ( '{(.)\1+}', '$1', $str );
$str = preg_replace ( '{[ \'-_\(\)]}', '', $str )

在 Java 中:

str = str.replaceAll("(.)\\1+", "$1");
str = str.replaceAll("[ '-_\\(\\)]", "");

我建议您提供您的输入和预期输出，然后您将获得有关如何在 PHP 和/或 Java 中完成的更好答案.
