試圖找出如何從數組中拉出並使用JTextArea顯示

Question

我想弄清楚如何從問題列表中拉出然後使用JTextArea輸出它們。現在我被困在試圖弄清楚如何從列表中隨機選擇然後輸出它。這是我迄今爲止。

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); 
    } 

Answer 1

迭代陣列的和顯示在JTextArea中

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); 
    }
