我有一個GUI將顯示五個隨機選擇的問題。問題限制受到下一個問題按鈕被按下的次數的限制。當用戶完成五個問題時,我希望他們按下應該重新啓動程序的開始新的一輪按鈕。
我從來沒有做過這樣的事情,我看過的代碼我不明白它是如何工作的。從Jbutton重新啓動程序和隨機問題
這裏是我的代碼:一切工作在這裏,我只需要添加重啓鍵/代碼
int nextQuestionClicked;//For number of times next question is clicked
//Method to generate random questions
private String setQuestions(){
int match = (int) Math.floor(Math.random()*cities.size());
String whatCity = cities.get(match);
String displayCity = "Where is " + whatCity + " located?";
return displayCity;
}
//What happens when next question is pressed
private void displayQuestionActionPerformed(java.awt.event.ActionEvent evt) {
boolean trueOrFalse;
submitButton.setEnabled(true);
displayQuestion.setEnabled(false);
outputTextQuestion.setText(null);
outputTextQuestion.setText(setQuestions());
outputAnswers.setText(null);
inputAnswer.setText(null);
outputDegree.setText(null);
nextQuestionClicked++;
int buttonLimit = 4;
if (nextQuestionClicked <= buttonLimit)
{
int correctAnswer = -1;
for (int x = 0; x < cities.size(); x++)
{
if (trueOrFalse = outputTextQuestion.getText().contains(cities.get(x)))
{
correctAnswer = x;
break;
}
}
randomAnswers = new ArrayList <Integer>();
Collections.addAll(randomAnswers, correctAnswer);
for (int x=0; x < 3; x++)
{
int r = correctAnswer;
while (randomAnswers.contains(r))
{
r = ((int)(Math.random()*100))%cities.size();
}
Collections.addAll(randomAnswers, r);
}
Collections.shuffle(randomAnswers);
outputAnswers.setText(null);
for (int r=0; r<randomAnswers.size(); r++)
{
int hint = randomAnswers.get(r);
outputAnswers.append(provinces.get(hint) + "\n");
}
inputAnswer.requestFocus();
}
else{
displayQuestion.setEnabled(false);
submitButton.setEnabled(false);
newRound.setEnabled(true);
outputTextQuestion.setText("Start New Round!!");
outputDegree.setText(null);
}
}
private void newRoundActionPerformed(java.awt.event.ActionEvent evt) {
outputTextQuestion.setText(null);
displayQuestion.setEnabled(true);
submitButton.setEnabled(false);
//What code do I do here to restart the program?
}
請幫幫忙!
在此先感謝!
所以你問我們爲你寫代碼?這不是一種編碼服務... – ItamarG3
*「我看過的代碼我不明白它是如何工作的」*這給了讀者一種印象,你不會理解我們提供的任何代碼。那麼爲什麼有人會試圖幫助?鏈接到你看到的例子,解釋你不明白的東西。嘗試一些東西,當你被困住並且有一個真正的問題(並且具體)時,回覆給我們。一般建議:爲了更快地獲得更好的幫助,請發佈[MCVE]或[簡短,獨立,正確的示例](http://www.sscce.org/)。 –
