So what do I do to "open" my array list of Appointment objects? I have tried iteration but it gets 2 correct displays, or repeats the last entry. I need to set the text fields to a variable inside an array of objects. How do I go about that? This a calendar that saves your appointments into an array list the catch that the list is of an object type called appointments. I am so close to finishing I just can not get what to do with displaying or setting the information into the text fields.

The code is not well written. Just consider how similar the code for all the days is. Why repeat yourself instead of coming up with a suitable data structure that allows you to access the objects more conveniently? Why create 2 x 7 TextFields when you can create 2 and use a loop to repeat the process?
One more thing you need to do is actually store the day of the week in you Appointment.
The open implementation in the following code assumes the content of the date list already contains the proper values even though currently the code only restores the last submitted values, if the user edits the TextFields.
private ArrayList<Appointment> date = new ArrayList<Appointment>();

final DayOfWeek day;
final String tiempo;

if (Character.isDigit(tiempo.charAt(0)) && tiempo.endsWith("a") || tiempo.endsWith("p")) {
this.tiempo = tiempo;
} else {
throw new IllegalArgumentException("First input must be numeric and a for am" + "p for pm");
}
this.d = d;
this.day = day;
}
}
public void submit() {
// add appointment for each entry in the map
inputs.forEach((day, inputs) -> {
date.add(new Appointment(inputs[0].getText(), inputs[1].getText(), day));
});
}
public void open() {
// clear fields
inputs.values().stream().flatMap(Arrays::stream).forEach(TextField::clear);
// set text for all elements of date
date.forEach(appointment -> {
TextField[] fields = inputs.get(appointment.day);
fields[0].setText(appointment.tiempo);
fields[1].setText(appointment.d);
});
}
