Simple way to compare 2 ArrayLists

Question

I have 2 arraylists of string object.

List sourceList = new ArrayList();
List destinationList = new ArrayList

        

Answer 1

boolean isEquals(List firstList, List secondList){
    ArrayList commons = new ArrayList<>();

    for (String s2 : secondList) {
        for (String s1 : firstList) {
           if(s2.contains(s1)){
               commons.add(s2);
           }
        }
    }

    firstList.removeAll(commons);
    secondList.removeAll(commons);
    return !(firstList.size() > 0 || secondList.size() > 0) ;
}
