I want to check whether it contains any members of my arrayList

I know I can iterate over the arrayList and then check for each element whether the string contains the element. I am looking for an efficient solution

This is my ArrayList

ArrayList<String> volIDsSent = new ArrayList<String>();
volIDsSent.add("60050768028080EF6400000000000AC3");
volIDsSent.add("60050768028080EF6400000000000FF8");

I would get the string from somewhere line by line .

Answer 1

Consider reading the array once and building a regex string by concatenating with “|” between each one, either manually or with something like StringUtils.join. Then use the regex against each line to read.
