Java 字符串包含

函数boolean containsAny(String str, String searchChars) 判断str字符串中是否包含searchChars字符串

String khh_str = "";
        if(list.size()>0){
            khh_str = "('";
            for (int i = 0; i < list.size(); i++) {
                String now_khh = list.get(i).getKhh().trim();
                if(!khh_str.contains(now_khh)){
                    if(i>0){
                        khh_str += "','";
                    }
                    khh_str += now_khh;
                }
            }
            khh_str += "')";
        }
