You may call U.difference(lists) method in underscore-java library. I am the maintainer of the project. Live example

import com.github.underscore.U;
import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List list1 = Arrays.asList(1, 2, 3);
        List list2 = Arrays.asList(1, 2);
        List list3 = U.difference(list1, list2);
        System.out.println(list3);
        // [3]
    }
}
