Getting char value from ComboBox in JavaFX - javafx

Question

I need to get the selected value in a combobox as of a data type char. I know how to get the selected item it's the conversion which I've got stuck on. Any suggestions?
This is the combobox and it content:
idCharCombo = new ComboBox<>();
idCharCombo.getItems().addAll("A","B","G","H","L","M","P","Z");
Now i will be using this data in a method which passes an int and a char (bellow is the use of the method where the second element is still an object rather than a char):
if (checkStaffMemberById(Integer.parseInt(idNoTxtFld.getText()), idCharCombo.getValue()) == true){
AlertBox.display("ID Validation", "ERROR! ID Already Exists.");
hope i arranged adequately

Answer 1

Since your combo box appears to only hold single-character strings, and you want to treat them as chars, the most obvious thing to do is to use a ComboBox<Character> instead of a ComboBox<String>. I.e. replace your declaration, which presumably looks like
ComboBox<String> idCharCombo ;
with
ComboBox<Character> idCharCombo ;
and then you can do
idCharCombo.getItems().addAll('A','B','G','H','L','M','P','Z');
Then
idCharCombo.getValue()
will return a Character which will be autounboxed to a char as needed, so your method call
checkStaffMemberById(Integer.parseInt(idNoTxtFld.getText()), idCharCombo.getValue())
should work as-is.
