Get the difference data of two sets

It can be used to remove inconsistent data between the database and the comparison set

public class TestList {
    
    public static void main(String[] args) {
    
        //  browser 
        List<String> list = Arrays.asList( "2", "3", "4", "5");
        //  database 
        List<String> list1 = Arrays.asList("1", "2", "4", "5", "7");
        List<String> list2 =new ArrayList<>();
        List<String> list3 =new ArrayList<>();
        // list1 Not found in 
        list2=list.stream().filter(e -> {
    
            return !list1.contains(e);
        }).collect(Collectors.toList());
        // list Not found in 
        list3=list1.stream().filter(e -> {
    
            return !list.contains(e);
        }).collect(Collectors.toList());
        System.out.println(list2);
        System.out.println(list3);
    }
}
