Trying to figure out how to pull from an array and display it using JTextArea

Question

I'm trying to figure out how to pull from a list of questions and then output them using JTextArea. Right now I'm stuck trying to figure out how to randomly select from the list and then output it. This is what i have so far.

public static void Question()
  {
    String[] quest = {"place", "hold", "er"};
    int[] questNum = {1, 2, 3};


    JTextArea question = new JTextArea(6, 20);
    question.setText("Question " + questNum + quest);
  }

Why not do away with `questNum` and simply use `quest`'s index plus 1 wherever you need that? — Tim M., Jul 18 '17 at 15:00

iterating array's and display in JTextArea

public static void Question()
  {
    String[] quest = {"place", "hold", "er"};
    int[] questNum = {1, 2, 3};

    String textContent = new String();
    for (int i = 0; i < quest.length; i++) {
     textContent += quest[i] + " ";
    }

    for (int i = 0; i < questNum.length; i++) {
     textContent += questNum[i] + " ";
    }

    JTextArea question = new JTextArea(6, 20);
    question.setText("Question " + textContent);
  }

I'd rather use `StringBuilder` than `String` in this case. – msagala25 Jul 17 '17 at 05:51
in this case, use of StringBuffer more preferable than String – Chirag Goti Jul 17 '17 at 06:50
