Question

I’m in the process of creating a method to generate a unique id, of type Integer, and was wondering how to do the following.

In my Object I want to call the generateUniqueID method from my setter method. The generateUniqueID will generate an incrementing number and then append it to a string

e.g. Reminder-1, Reminder-2 etc….

I’m not quite sure how to do this though and was wondering if anyone could help?

Thank you

As long as there is no concurrency.

private static int reminderID = 1;

public synchronized static String generateUniqueID() {
    String uniqueId = "Reminder-" + reminderID;
    reminderID++;
    return uniqueId;
}
