java String contains逻辑的优化

Question

有一个"AAA,BBB"格式的字符串组成的List,有一个字符串SSS现在想遍历List，如果字符串SSS中包含了AAA，并且包含了BBB，则返回ture。否则将List全部遍历，都不符合条件则返回false。 目前的思路是在遍历List的时候...

Easy，With Java 8:

   public boolean isContain(List strings, String sss) {
    return Objects.nonNull(sss)
        && (!sss.isEmpty())
        && strings
        .stream()
        .map(s -> s.split(","))
        .map(Arrays::stream)
        .anyMatch(string -> string.allMatch(sss::contains));
}

LZ can consider using HashSet collection.

Can you test whether this regular expression works?

But it feels like it’s not very good to spell a regular string.

    boolean flag = flase;
   
    String regex="[A]{3}.*[B]{3}";
    
    Pattern pattern = Pattern.compile(regex);
    
    Matcher matcher = pattern.matcher(SSS);
    
    if(matcher.matches()) {

         flag=ture;

    }     
    return flag;
