java - JRadioButtons before every line -

i have program reads questions multiple choice answers text file , displays random set of them in joptionpane (very question in new pane). in text file questions , 4 options of answers in 1 line , divide them new lines. want try add jradiobuttons before every single answer. there can me. thank in advance. here code:

random random = new random();         (int = 0; < newranques; i++) {              int randindex = random.nextint(32) + 0;             string randomquestion = questions.get(randindex);             randomquestions.add(randomquestion);             string different = randomquestion.replaceall(";", "\n");             {                 joptionpane.showmessagedialog(null, different, "question", joptionpane.information_message);                  jradiobutton answera = new jradiobutton("a) " + answer[0]);                 jradiobutton answerb = new jradiobutton("b) " + answer[1]);                 jradiobutton answerc = new jradiobutton("c) " + answer[2]);                 jradiobutton answerd = new jradiobutton("d) " + answer[3]);                  buttongroup group = new buttongroup();                 group.add(optiona);                 group.add(optionb);                 group.add(optionc);                 group.add(optiond);                  return;             } 

this should it:
