Ordenar por data em ArrayList

ArrayList tem um sort, podes usa-lo desta forma:

		List<Consulta> list  = new ArrayList<>();

        Consulta consulta1 = new Consulta("11/01/2000");
        Consulta consulta2 = new Consulta("11/01/1990");

        list.add(consulta1);
        list.add(consulta2);

        List<Consulta> list2 = list.stream().sorted(Comparator.comparing(Consulta::getDate)).collect(Collectors.toList());

        for(Consulta consulta : list){
            System.out.println(consulta.getDate());
        }

Nota que a única coisa que eu fiz foi no construtor recebo uma String e com SimpleDateFormat "dd/MM/yyyy" crio uma data.
