I have two string containing dates dataSalva and dataDoDia and I’m wondering if the dataDoDia and 5 days longer than dataSalva how do I do this

    SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
    Date data = new Date();
    Calendar cal = Calendar.getInstance();
    cal.setTime(data);
    Date data_atual = cal.getTime();
    String dataDoDia= dateFormat.format(data_atual);

Caught this data_completaand saved at the bank Ai when I enter I open the application I want to take this date in the bank and compare with the date of the day , that I will take the same way the date has been saved

String dataSalva = banco.get();

here I will have the date that is already saved then I’ll do the top part to get the date of the day

I want to compare these two dates dataSalva and dataDoDia

Put your code... It is better, because we will have more information, as the date format...

data is the dataSalva? I imagine that data_atual be the DataATual. Your code does not match the description of the question. Does this code have any relevance? Or is the question wrong?

I gave an answer but I do not know if it is what you want since you do not have more information. I note that the last edition introduced a new name for the date.

I switched so as not to confuse

In general everyone recommends using the Jodatime which is much better than the original API. But you can do the following:

(DataAtual.getTime() - DataSalva.getTime()) / (1000 * 60 * 60 * 24) == 5

I put in the Github for future reference.

Java now has a more modern official API that is practically Jodatime.
