我正在使用 Cucumber 來測驗開源 Java Swing 應用程式。我嘗試了很多方法來在彈出的 JOptionPane 上單擊“是”（例如設定 ch = 0 和 ch = JOptionPane.YES_OPTION），但它不起作用。這是代碼：
public JButton btnAdd;
public int ch;
btnAdd = new JButton("Add");
btnAdd.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String name=textField.getText();
double bal=Double.parseDouble(textField_1.getText());
double maxw=Double.parseDouble(textField_2.getText());
if(bal<2000) {
JOptionPane.showMessageDialog(getComponent(0), "Minimum Limit 5000", "Warning", 0);
textField.setText(null);
textField_1.setText(null);
textField_2.setText(null);
}
else {
if(name==null||bal<=0||maxw<=0) {
JOptionPane.showMessageDialog(getComponent(0),"Typing Mismatch!! Try Again");
textField.setText(null);
textField_1.setText(null);
textField_2.setText(null);
}
else {
ch=JOptionPane.showConfirmDialog(getComponent(0), "Confirm?");
if(ch==0) {
int index = FileIO.bank.addAccount(name, bal, maxw);
DisplayList.arr.addElement(FileIO.bank.getAccounts()[index].toString());
JOptionPane.showMessageDialog(getComponent(0),"Added Successfully");
dispose();
}
else {
JOptionPane.showMessageDialog(getComponent(0),"Failed");
textField.setText(null);
textField_1.setText(null);
textField_2.setText(null);
}
textField.setText(null);
textField_1.setText(null);
textField_2.setText(null);
}
}
}
有沒有辦法可以單擊“是”？謝謝！

這是一個示例，如何在出現的所有選項對話框中按“是”按鈕
