Retrieve values from database to jradiobutton

Question

I'm trying to implement a payroll system and I got some issues with the updating employees. I have stored the gender of the employees as a varchar in my DB. When I type in the employee id and click search button I want to get that info out of the database and display it in a male/female radio buttons according to the data. There are no errors in the code. but the problem is when I try to do that only male button appear selected which is by the way the default. Female radio button doesn't get selected even when the the data on the DB says Female. Can anybody please help me with this issue? below is my code.

Answer 1

replace the lines

if (GN =="Female"){
            MaleRadio.setSelected(false);
            FemaleRadio.setSelected(true);

        }
        else{
            FemaleRadio.setSelected(false);
            MaleRadio.setSelected(true);
        }

with

        if (GN.equals("Female")){
            MaleRadio.setSelected(false);
            FemaleRadio.setSelected(true);
        } else {
            FemaleRadio.setSelected(false);
            MaleRadio.setSelected(true);
        }

as == is used to compare the hash and values & .equals is used to check the values only..
