Question

I have a JComboBox which contains some employee ID numbers (which are integer values).

I want to set ‘Select employee’ to the JComboBox as a default value. As this value is in string format its throwing me an exception like “java.lang.NumberFormatException: For input string: “Select Employee””.
How do I do this?

My code is:

public void clear()
 {
    cmb_emp_id.setSelectedItem("Select Employee");
    txt_emp_name.setText("");
    txt_department.setText("");
    txt_designation.setText("");
    joining_date.setDate(new Date());
    resign_date.setDate(new Date());
    txt_description.setText("");
 }

How can I accomplish this?

Answer 1

It’s hard to tell exactly what you’re after, especially since you’re talking about a number format exception.

However, to reset a JComboBox to it’s original selection, you simply do

cmb_emp_id.setSelectedIndex(0);
