如果 "illegal start of expression"

Question

我正在为我的计算机科学制作一个折扣 GUI class。我们要"Create an application that prompts the user for the amount of purchases and then returns the discounted price."

我已经创建了我的程序，但我一直收到表达式错误的非法开始。

private void CalculateDiscountActionPerformed(java.awt.event.ActionEvent evt) {                                                  
    // declaring variables
    double dblInitialPrice;
    double dblDiscount;
    double dblTotalPrice;
    double dblTotal;

    DecimalFormat Formatter = new DecimalFormat("###.00");

    // assigning values to variables
    dblInitialPrice = Double.parseDouble(AmountOfPurchases.getText());
    dblDiscount = dblInitialPrice * (0.10);
    dblTotalPrice = dblInitialPrice - dblDiscount;
    dblTotal =  
    if (dblInitialPrice >= 10)  { // error here "illegal start of expression" for if
        DiscountPrice.setText("" + Formatter.format(dblDiscount) + "$");
        DiscountAmount.setText("" + Formatter.format(dblTotalPrice) + "$");
    } else if (dblInitialPrice <= 10){
        DiscountPrice.setText("0.00$");
        DiscountAmount.setText("" + dblInitialPrice + "$");
    }

Answer 1

dblTotal = 不是一个完整的表达式。你需要右边的东西。
