設置選定的單選按鈕-NetBeans Swing

Question

if(DishFormWeekNoWeek1Rb.hasFocus() == true){
    DishFormWeekNoWeek1Rb.setSelected(hasFocus());
    System.out.print(DishFormWeekNoWeek1Rb.getComponents().getClass().toString());
}

如何改進上面的代碼，以便在選中單選按鈕時也將其選中？ 因為我正在使用Tab鍵轉到下一個單選按鈕，所以我想要的是當我按Tab鍵並專注於單選按鈕時，它也會被選中。 給定的意見和建議表示贊賞。

if(DishFormWeekNoWeek1Rb.hasFocus() == true){

            DishFormWeekNoWeek1Rb.setSelected(true);
            DishFormWeekNoWeek1Rb.requestFocus(true);
            System.out.print(DishFormWeekNoWeek1Rb.getComponents().getClass().toString());
        }
