我有以下測試另一個類(MyDate)的類(testDate),當這3行被執行時,inputDialog框沒有關閉取消或稍微'x'右上角。Java - 當按下取消或'x'時,我的JOptionPane沒有關閉
myDay = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the day of the month, you're travelling on: "));
myMonth = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the month (1-12), you're travelling on: "));
myYear = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the year, you're travelling on: "));
以下是完整的testDate類:
import javax.swing.JOptionPane;
public class testDate {
public static void main(String[] args){
int myDay = 0, myMonth = 0, myYear = 0; // initialising variables
boolean dateCorrect = false;
MyDate userTravelDate;
do {
try {
do {
myDay = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the day of the month, you're travelling on: "));
myMonth = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the month (1-12), you're travelling on: "));
myYear = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the year, you're travelling on: "));
userTravelDate = new MyDate(myDay, myMonth, myYear);
} while (userTravelDate.isDateValid(userTravelDate.formDate()) == false);
dateCorrect = true;
}
catch (Exception e) {
JOptionPane.showMessageDialog(null, "Please enter only integers!", "Error Occurred!", JOptionPane.ERROR_MESSAGE);
}
} while (dateCorrect == false);
JOptionPane.showMessageDialog(null, myDay + "-" + myMonth + "-" + myYear);
}
}
我想知道,如果輸入對話框可以被關閉,如果我按「X」或取消,因爲在當'x'或者取消被按下的時候它執行該行:
JOptionPane.showMessageDialog(null, "Please enter only integers!", "Error Occurred!", JOptionPane.ERROR_MESSAGE);
並且持續循環詢問白天,月份和年份,直到這些都是正確的。
哦,我看到的,謝謝。 – Khalid 2013-03-27 15:55:28
