First of all:

  1. Variable names should NOT start with an upper case character. Some of your variables are correct. Others are not. Be consistent!!!

  2. The "action command" defaults to the text on the button, so assuming you use "Male" and "Female" as the text of each radio button you don't need to set the "action command" directly.

I have two butons to select gender,and I want to check if the user selected one of them.

Well you need to know when to do this check. Presumably you have some kind of "Save" button that the user clicks to process all the data that has been entered on the form. So in the ActionListener for this button you would add logic to validate the selection of one of the radio buttons.

Something like:

ButtonModel model = buttonGroup1.getSelection();

if (model != null)
{
    s.setGender(model.getActionCommand().charAt(0))
}
else
{
    //error
}

Or the other approach is to just add an ActionListener to each radio button. When the button is selected you set the "gender" value. Then when you click the "Save" button you check if the "gender" property has a value. If not, do your error processing.

You probably don't need a try...catch, just use a simple if statement (or two):

if (radioButton1.isSelected()) {
    // do something
}
else if (radioButton2.isSelected()) {
    // do something else
}
