Java radio button selection and proceed

Question

I want to have the user to select either one of the choices. but my code doesnt work. not sure if i got it wrong

if (!jRadioMale.isSelected() || !jRadioFemale.isSelected()) {
  JOptionPane.showConfirmDialog(rootPane, 
      "Please Select Male or Female", 
      "", 
      JOptionPane.OK_CANCEL_OPTION);
} else {
  // Continue to next
}   

it keeps prompting "Please select male or female" even if one is selected!

Answer 1

You need to do this ...

 if(jRadioMale.isSelected() || jRadioFemale.isSelected()){
    //Continue to next           

            }
    else{
     JOptionPane.showConfirmDialog(rootPane, "Please Select Male or Female", "", JOptionPane.OK_CANCEL_OPTION);

    }   

Your code will always show the alert because Your condition returns true if any one of the button is not selected

Answer 2

Instead of OR (will keep prompting, because when one is selected the other IS NOT)

if (!jRadioMale.isSelected() || !jRadioFemale.isSelected()) {

you really want AND (when either is selected)

if (!jRadioMale.isSelected() && !jRadioFemale.isSelected()) {

or you could use the negation of the AND

if (!(jRadioMale.isSelected() || jRadioFemale.isSelected())) {

Answer 3

   if (!jRadioMale.isSelected() && !jRadioFemale.isSelected()) {
  JOptionPane.showConfirmDialog(rootPane, 
      "Please Select Male or Female", 
      "", 
      JOptionPane.OK_CANCEL_OPTION);
} else {
  // Continue to next
}   

Use AND instead of OR

Answer 4

I agree with @Elliott Frisch. The problem is in the following code:

!jRadioMale.isSelected() || !jRadioFemale.isSelected()

For this expression, two situations will satisfy: 1.User has selected no radio. 2.User has selected only one radio. In this case, !jRadioMale.isSelected() or !jRadioFemale.isSelected() will be satisfied, which make the total expression is true.

I think you may want to the expression is true only under situation 1. You can modified your code as following: !jRadioMale.isSelected() && !jRadioFemale.isSelected()

Wish my answer may give you some help.

Answer 5

I am afraid you need to get rid of ! , so it will works

    if(jRadioMale.isSelected()|| jRadioFemale.isSelected()){                       
                }else{
 JOptionPane.showConfirmDialog(rootPane, "Please Select Male or Female", "", JOptionPane.OK_CANCEL_OPTION);
