[SOLVED] Comparing values obtained from combo box to another string fails even though both appear to be the same

Comparing values obtained from combo box to another string fails even though both appear to be the same

I am trying to obtain a date from 3 separate combo boxes that I then convert to ints and make a Date object. However, when I compare this date string to an already existing string, it doesnt match even though in the debugger it appears to be the same. I have setup a simple if statement to check what the problem is however I am not sure why it does not match.

int apptDay, apptMonth, apptYear;
apptDay = Integer.parseInt(consultationDay.getSelectedItem().toString());
apptMonth = Integer.parseInt(consultationMonth.getSelectedItem().toString());
apptYear = Integer.parseInt(consultationYear.getSelectedItem().toString());
consultationDate = new Date(apptDay, apptMonth, apptYear);



if (appointmentList.get(0).getDate() == consultationDate) {
    sopl("Working");
}

I am quite sure that there is some issue with my code related to combo boxes as that is the only place where I face problems. The if statement is never satisfied so "Working" is never printed.

Any help would be appreciated.

Solution

You should use .equlas() instead of the == operator.

int apptDay = 5, apptMonth = 12, apptYear = 2000;
Date testDate = new Date(apptDay, apptMonth, apptYear);
Date consultationDate = new Date(apptDay, apptMonth, apptYear);

if (testDate == consultationDate) {
    System.out.println("Success for ==");
} else if (testDate.equals(consultationDate)) {
    System.out.println("Success for equals");
}
