Good afternoon. I want to set the option of a Jcombobox field as the registered option in a given vector position. For a previous text field, I made the following settings:

campoCpf.setText(vetAluno[i].getCpf());

To set the Jcombobox, as I would call the selected option of the array, assuming, for example, 3 options, if I selected one of them and the register was saved as that option chosen, how to call?

I know I must set the field like this:

campoCurso.setSelectedIndex();

but which parameter should I pass?

  • You have a variable and you want the JComboBox select the position that has the value of this variable, is this?

Just pass the object you want to select within the method setSelectedItem.

Thus: 

String [] s = {"orange", "pear", "apple", "banana"};

JComboBox test = new JComboBox(s);
test.setSelectedItem("banana");

The method setSelectedIndex, that you mentioned, select by the position in the vector. If we wanted to select banana using it, would look like this:

String [] s = {"orange", "pear", "apple", "banana"};

JComboBox test = new JComboBox(s);
test.setSelectedIndex(3);
