java - 从字符串中删除特殊字符？

Question

我有类似的字符串

Join our<\/strong>\u00a0<strong>&#8220;Worldwide Host Your Own Screening Tour!

而且我要

Join our Worldwide Host Your Own Screening Tour!

我的代码::

String str = "Join our<\/strong>\u00a0<strong>&#8220;Worldwide Host Your";
System.out.println(str.replaceAll("<\/strong>\u00a0<strong>&#8220;", " "));

错误

 Invalid escape sequence (valid ones are  \b  \t  \n  \f  \r  \"  \'  \\ )

Answer 1

尝试这个：

String str = "Join our<\\/strong>\u00a0<strong>&#8220;Worldwide Host Your";
System.out.println(str.replaceAll("<\\\\/strong>\\u00a0<strong>&#8220;", " "));

String.replaceAll需要一个正则表达式。

您也可以使用StringUtils（这有点简单）：

StringUtils.replace(str, "<\\/strong>\u00a0<strong>&#8220;", "")

Answer 2

试试看。

    String s="Join our<\\/strong>\u00a0<strong>&#8220;Worldwide Host Your Own Screening Tour!";
    System.out.println(s.replaceAll("<\\\\/strong>\\u00a0<strong>&#8220;", " "));
