如何使用正则表达式删除字符串中的标点符号

Question

我编写了一个Java程序来删除字符串

中的所有标点符号

"1.1 Interactive systems  In today's world, interacting with computer-based devices and systems is commonplace."

如何使用正则表达式删除带有此字符串的标点符号

"11 Interactive systems  In todays world interacting with computerbased devices and systems is commonplace".

Answer 1

使用字符串replaceAll和正则表达式

String mystring = "\"1.1 Interactive systems  In today's world, interacting with computer-based devices and systems is commonplace.\"";

String replaced = mystring.replaceAll("\\p{Punct}", "");

实际正则表达式是\p{Punct}但我们需要转义\因此另一个反斜杠。

输出

11 Interactive systems  In todays world interacting with computerbased devices and systems is commonplace
