有三个字符串如何匹配同时包含两个关键字的字符串

// regExp (?=.*我是谁)(?=.*C)^.*$
// java code
List<String> list = Arrays.asList(new String[]{
     
    "this is the first check run",
    "the first run",
    "the first time runing"
});
 
List<String> matches = new ArrayList<String>();
 
for(String word : list){
     
    //包含check且包含first
    if(word.matches("(?=.*check)(?=.*first)^.*$"))
        matches.add(word);
}
 
System.out.println(Arrays.toString(matches.toArray()));
