How to make several selects with a choice from one array of values?

Question

Java

There is a form with field matching, for each field you need to select a value from an array of values, and for each field the value must be unique. Is there a way to do this without much effort?

Answer 1

You can use it as EVGENY T suggests.
You can immediately pass it to the class where you will use it:

public void n_ot() {
        num_of_tr.get().addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
            @Override
            public void onSuccess(DocumentSnapshot documentSnapshot) {
                if (documentSnapshot.exists()) {
                    //String amount_not = documentSnapshot.getString(AMOUNT);
                    //anotherClass.setAmountNot(amount_not);
                    anotherClass.setAmountNot(documentSnapshot.getString(AMOUNT));
                }
            }
        });
    }

public class AnotherClass{
    String amount_not;
    //...
    public void setAmounntNot(String value){
        this.amount_not = value;
    }
    //...
}
