在 jOptionPane 中执行 while 循环退出

Question

考虑以下代码。出于某种原因，即使在点击 NO 按钮后，它也会退出 do while 循环。我最近引入了 recentPurchaseAmount 变量，之后它就停止工作了。即使删除它现在也无法正常工作。

像 purchaseAmount 、 recentPurchaseAmount 这样的变量是 double 类型，初始化为 0.0。 itemNo, itemCheck 为整型变量

do {
    purchaseAmount = Double.parseDouble(JOptionPane.showInputDialog(
        "Enter the Item Purchase Amount"));
    recentPurchaseAmount = recentPurchaseAmount + purchaseAmount;

    if (onepty.budgetAmountVerify(recentPurchaseAmount)) {
        itemNo++;
        itemCheck = JOptionPane.showConfirmDialog(null,
            "Finished Purchasing Items Purchase Amount?",
            "Say Yes or No", JOptionPane.YES_NO_OPTION); 

        remainingBal = onepty.remainingBalance(recentPurchaseAmount);        
    }
}   while(itemCheck == JOptionPane.YES_OPTION);

JOptionPane.showMessageDialog(null, 
    "Total items purchased are " + itemNo + 
    "\n and the remaining balance is : " +remainingBal+"" ,
    "This is the Title",JOptionPane.INFORMATION_MESSAGE);

Answer 1

while(itemCheck == JOptionPane.NO_OPTION);会是比较合适的条件
