Is it possible to populate a JComboBox with an int[]? I am writing a code that will use a JComboBox populated with years (in integers).
The code I have written is this:
int[] birthYear = new int[currentYear]; //currentYear is an int variable
int inc=1;
for(int i=0;i<currentYear;i++)
{
birthYear[i]= inc;
inc++;
}
birthYearBox = new JComboBox(birthYear); //this is the line in which the error occurs
I want these to integers in the ComboBox so that I can subtract from them. Do I have to populate the ComboBox with strings, then make them integers after they have been input? Or is there a way to actually populate the ComboBox with the int[]?
JCombobox
is generic, but Java generics don't support primitive type (and int
is a primitive type).
So use an Integer
array instead :
Integer[] birthYear = new Integer[currentYear]; //currentYear is an int variable
int inc=1;
for(int i=0;i<currentYear;i++){
birthYear[i]= inc;
inc++;
}
JComboBox<Integer> birthYearBox = new JComboBox<>(birthYear);
