Java：我的编译器说我的一个printf语句坏了，我不知道为什么[重复]

Question

这是我第一次问问题，如果这看起来很奇怪，很抱歉。这是我的完整代码。和星星分开的线就是断裂的线。

import java.util.Scanner;
public class CashRegister
{
    public static void main(String[] args)
    {
        Scanner keyboard = new Scanner(System.in);
        double price;
        final double TAX_RATE = 0.085;
        final double SURCHARGE = 0.04;
        final int MAX_PRICE = 500;
        double addedSurcharge = 0;
        do
        {
            do
            {
                System.out.print("Cost of Item (enter 0 or negative value to exit; max is $500.00): ");
                price = keyboard.nextDouble();
            } while (price > 500);
            int dollars = (int) price;
            int cents = (int) price - dollars;
            int convertPrice = (dollars * 100) + cents;
            if (convertPrice < 1500)
            {
                addedSurcharge = (convertPrice * SURCHARGE) / 100;
                System.out.printf("Surcharge of $%.2f added.", addedSurcharge);
                System.out.println();
            }
            double withTax = ((convertPrice * TAX_RATE) / 100) + addedSurcharge + convertPrice;

        **System.out.printf("Amount due (with 8.5% tax): $%.2f", withTax);**

        System.out.println();
    } while (price > 0);
    System.out.println("Done.");
}

您需要转义用作百分比符号的百分比符号:8.5%%而不是8.5%
