如何停止此循环？

Question

如果我按下＃34; no＆＃34;如何停止此无限循环？在确认对话框上？

        int loop=0;
        do
        {
            System.out.println("Select your food. 1");
            int f=scan.nextInt();
            if(f==1)
            {
                System.out.println("\nHow many tenderloin do you like? ");
                ps=scan.nextInt();
                pst=ps*55;
            }
            System.out.println("Select your drinks. 1");
            int d=scan.nextInt();
            if(d==1)
            {
                System.out.println("\nHow many filtered water do you want? ");
                fw=scan.nextInt();
                fwt=fw*16;
            }
            int buttonClicked=JOptionPane.showConfirmDialog(null, "Do You Want To Order Again?","Confirm",JOptionPane.YES_NO_OPTION);
        }
        while(JOptionPane.YES_NO_OPTION!=done);
        loop++;
            System.out.println("TOTAL: ");
    }
}

我无法获得逻辑。

Answer 1

将buttonClicked的定义移到循环外部。并根据值JOptionPane.YES_OPTION进行测试。像，

int buttonClicked;
do
{
  // ...
  buttonClicked = JOptionPane.showConfirmDialog(null, 
          "Do You Want To Order Again?","Confirm",JOptionPane.YES_NO_OPTION);
} while(buttonClicked == JOptionPane.YES_OPTION);

Answer 2

将此行while(JOptionPane.YES_NO_OPTION!=done);更改为while(JOptionPane.NO_OPTION!=buttonClicked);
