如何获得所需的输出？

输入字符串-

"Software Industry. software Industry. SOFTWARE INDUSTRY. software industry. "

要搜索的词 -

"software industry"

输出 -

"*Software Industry*. *software Industry*. *SOFTWARE INDUSTRY*. *software industry*. "

简而言之，我必须找到一个短语并用星号(*)开头和结尾替换相同的短语，忽略大小写..

您可以将 replaceAll 与 (?i) 一起使用，这将进行不区分大小写替换。

String str = "Software Industry. software Industry. SOFTWARE INDUSTRY. "+
                                                    "software industry. "
str = str.replaceAll("(?i)(software industry)", "\\*$1\\*");
