我需要用户为我的2个翻倍输入，但有'；这是一个初始化错误，但我不知道'；I don’我不想要一个双人号码（Java） import java.util.Scanner； 公共班机{ 公共静态void main（字符串[]args）{ 扫描仪扫描=新扫描仪（System.in）； 双小时； 工作两小时； 重瓣罗缎； grossPay=小时数*工作小时数； 含税浮动=（浮动）0.1； 浮动税=（浮动税）0.12； 浮动比格尔税=（浮动）0.15； 浮动巨税=（浮动）0.2； 双倍bigNetpay=（格罗斯佩-格罗斯佩*bigTax）； 双倍biggerNetpay=（格罗斯佩-格罗斯佩*biggerTax）； 双倍giantNetpay=（格罗斯佩-格罗斯佩*giantTax）； 双倍净支付=（格罗斯佩-格罗斯佩*含税）； System.out.println（“输入您工作的小时数：”； hourlyPR=scan.nextDouble（）； System.out.println（“输入您赚取的金额：”）； hoursWorked=scan.nextDouble（）； 如果（格罗斯比=300.01&&格罗斯比=400.1&&格罗斯比=500.1）； System.out.println（“每小时$”+hourlyPR+“&“+hoursWorked+”工时…”）； println（“税前，$”+grossPay+“+”和税后，$”+giantNetpay+”）； } }

我需要hoursworked和hourlypay双倍作为用户输入，而不是初始化。一切似乎都很好，但事实上，我无法为这两个替身获得用户输入。

这里至少有一个问题。在尝试使用扫描调用之前，请将其移至顶部

import java.util.Scanner;


public class Main {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        double hourlyPR ;
        double hoursWorked ;
        double grossPay;
        grossPay = hourlyPR * hoursWorked ;

        float Withtax = (float) 0.1;
        float bigTax = (float) 0.12;
        float biggerTax = (float) 0.15;
        float giantTax = (float) 0.2;

        double bigNetpay = (grossPay - grossPay * bigTax);
        double biggerNetpay = (grossPay - grossPay * biggerTax);
        double giantNetpay = (grossPay - grossPay * giantTax);
        double netPay = (grossPay - grossPay * Withtax);

        System.out.println("Enter The Amount of Hours You've Worked:");
        hourlyPR = scan.nextDouble();
        System.out.println("Enter The Amount You've Earned:");
        hoursWorked= scan.nextDouble();



            if (grossPay <= 300.00) {

                System.out.println("With $" + hourlyPR + " per hour & " + hoursWorked + " hours worked...");
                System.out.println("You make: $" + grossPay + " before taxes, " + "and $" + netPay + " after taxes.");
            } else if (grossPay >= 300.01 && grossPay <= 400) {
                System.out.println("With $" + hourlyPR + " per hour & " + hoursWorked + " hours worked...");
                System.out.println("You make: $" + grossPay + " before taxes, " + "and $" + bigNetpay + " after taxes.");

            } else if (grossPay >= 400.1 && grossPay <= 500) {
                System.out.println("With $" + hourlyPR + " per hour & " + hoursWorked + " hours worked...");
                System.out.println("You make: $" + grossPay + " before taxes, " + "and $" + biggerNetpay + " after taxes.");
            } else if (grossPay >= 500.1);
        System.out.println("With $" + hourlyPR + " per hour & " + hoursWorked + " hours worked...");
        System.out.println("You make: $" + grossPay + " before taxes, " + "and $" + giantNetpay + " after taxes.");

    }
}
