java - 不区分大小写的搜索和替换

Question

我有以下字符串，如何在Java中搜索和替换它？

之前

*animal is a *ANImal and *Bird is a *bIrd.

搜索并替换后，应该是*动物=狗和*鸟=孔雀

Dog is a Dog and Peacock is a Peacock.

我尝试用这种模式替换出现-（？i）\\ * animal但它不起作用。我究竟做错了什么？

   public String replaceStrPattern(String str, String pattern, String replaceWith) {

            String newStr = str;
            String nonAlphaNumeric = "[^a-zA-Z0-9]";

    String[] words = str.split(" ");
    for(String word : words) {
               word = word.replaceAll(nonAlphaNumeric, "").trim();
        if(word.equalsIgnoreCase(pattern))
            newStr = newStr.replace(word, replaceWith);
    }

        return newStr;      
}
