Answer 1

あなたはイテレータが実際に移動することができますので、あなたのGUIオブジェクトにあなたの質問と回答を渡す必要があります次の「結果」。

guiはこれらの質問にアクセスすることができず、gui内からメインから収集した結果から情報を得ることができないため、メイン関数ではなく次のボタン内で次の結果に移動する必要がありますデータファイル。

main関数から 'gui3'オブジェクトコンストラクタにファイルの初期読み込みを移動し、 'results' ArrayListをguiのインスタンス変数として使用可能にすることを検討してください。

この最初のJSONファイルの読み込みは、使用している乱数と非常に混同されますが、答えを1つの配列にまとめる方法を見つけることになります。

例：

ArrayList<ArrayList<String>> results = new ArrayList<ArrayList<String>>(); 
ArrayList<String> question = new ArrayList<>() 
question.add(question); 
question.add(answer1); 
question.add(answer2); 
question.add(answer3); 
question.add(answer4); 
results.add(questions); 

ボタン、「次へ」を押して操作を行うときに、あなたは配列にJSONを取得する方法についてのコメントに質問をもとに

jLabel1.setText(results.get(i).get(0)); 
jButton1.setText(results.get(i).get(1)); 
jButton2.setText(results.get(i).get(2)); 
jButton3.setText(results.get(i).get(3)); 
jButton4.setText(results.get(i).get(4)); 
i++; // Or use your setter() function? 

をすることができますリストを作成するには、現在の方法と非常によく似ていますが、すぐに使用するのではなく、ArrayListに追加する必要があります。

ような何か：

JSONParser parser = new JSONParser(); 
Object obj = null; 
obj = parser.parse(new FileReader("c:\\Matematika.json")); 
JSONObject jsonObject = (JSONObject) obj; 
JSONArray array = (JSONArray) jsonObject.get("data"); 
ArrayList<ArrayList<String>> results = new ArrayList<ArrayList<String>>(); 
ArrayList<String> question = new ArrayList<>(); 

Iterator<Object> iterator = array.iterator(); 
while (iterator.hasNext()) { 
    String questionString = element.get("soal"); 
    question.add(questionString); 
    JSONArray answers = (JSONArray) jsonObject.get("jawaban"); 
    Iterator<String> iterator2 = answers.iterator(); 
    int count = 0; 
    //The following limits it to pulling back 4 answers from the JSON jawaban element 
    while (iterator2.hasNext() && count < 4) { 
     String answer = iterator2.next(); 
     question.add(answer); 
     count++; 
    } 
    results.add(question); 
} 

あなたgui3オブジェクトのコンストラクターに入れ、このコードを - このようなまたはあなたのgui3コンストラクタにこれを渡すと、コンストラクタを作る結果：

public class gui3 extends javax.swing.JFrame { 
    ArrayList<ArrayList<String>> results; 

    //Your other code here 

    public gui3(ArrayList<ArrayList<String>> results) { 
     this.results = results; 
     initComponents(); 
    } 

    // Your other code here 
} 

。なお、このResultListがClass Instanceスコープにある必要があります。そのため、コンストラクタの外側で宣言を移動する必要があります。
