java循环重复程序 [英] java loop to repeat program

问题描述

对于Java来说我是一个非常陌生的人，我大约在第二周上课-

I am extremely new to java I am in my second week in classes or so--

我需要我的程序根据用户的要求继续运行或退出.这是一个薪资计算，我想让结尾说您是否要继续(y/n)".我希望Y重复我的整个问题计划，而不是结束计划.我正在使用Jgrasp，而且我很新.我假设它需要一个循环，但我不太确定，我只是让它可以正确运行和编译-对我来说它可以正确运行，所以这是一个不错的开始，我希望在我这样做时能获得帮助我看到了很多不同的方式和不同的程序.谢谢.

I need my program to keep going or exit according to the user. It is a payroll calculation and I want the end to say "Do you want to continue (y/n)" I want Y to repeat my entire program of questions and no to end program. I am using Jgrasp and I am very very new. I am assuming it needs a loop and I am not totally sure, I just got this to run and compile correctly-- it runs correctly for me so it is a good start and I am hoping to get help on how to do this as I am seeing a ton of different ways and different programs for it. thanks.

import java.util.Scanner;

public class calculations {
    public static void main(String [] args) {
        Scanner reader = new Scanner(System.in);
        Scanner in = new Scanner(System.in);

        double Regpay;
        double Payperhour;
        int HoursAweek;
        double Pay;
        double OvertimeHours;
        double OvertimePay;
        double Dependants;
        double SocSecTax;
        double FederalTax;
        double StateTax;
        int UnionDues;
        double AllTaxes;
        double FinalPay;
        String playAgain;

        System.out.print("Enter your pay per hour:");
        Payperhour = reader.nextDouble ();

        System.out.print("Enter your regular Hours a week:");
        HoursAweek = reader.nextInt();

        System.out.print("Enter your overtime hours:");
        OvertimeHours = reader.nextDouble();

        Regpay = Payperhour * HoursAweek;

        OvertimePay = OvertimeHours * 1.5 * Payperhour;

        Pay = OvertimePay + Regpay;

        SocSecTax = Pay * .06;

        FederalTax = Pay * .14;

        StateTax = Pay * .05;

        UnionDues = 10;

        AllTaxes = SocSecTax + FederalTax + StateTax + UnionDues; 

        FinalPay = Pay -= AllTaxes;

        System.out.println("Your pay this week will be " +FinalPay);

        {


            System.out.println("How many Dependants:");
            Dependants = reader.nextInt();

            if (Dependants >= 3) {
                Dependants = Pay + 35;
                System.out.println("Your Pay is:" +Dependants);
            } else if(Dependants < 3) {
                System.out.println("Your Pay is:" +Pay);
            }

        }

    }   

}

以下是代码的基本概念:

Here is the basic idea with your code:

import java.util.Scanner;

public class calculations{
    public static void main(String [] args) {
        Scanner reader = new Scanner(System.in);
        Scanner in = new Scanner(System.in);


        double Regpay;
        double Payperhour;
        int HoursAweek;
        double Pay;
        double OvertimeHours;
        double OvertimePay;
        double Dependants;
        double SocSecTax;
        double FederalTax;
        double StateTax;
        int UnionDues;
        double AllTaxes;
        double FinalPay;
        String playAgain;
        int runAgain = 1;

        while (runAgain == 1) {


            System.out.print("Enter your pay per hour:");
            Payperhour = reader.nextDouble();

            System.out.print("Enter your regular Hours a week:");
            HoursAweek = reader.nextInt();

            System.out.print("Enter your overtime hours:");
            OvertimeHours = reader.nextDouble();

            Regpay = Payperhour * HoursAweek;

            OvertimePay = OvertimeHours * 1.5 * Payperhour;

            Pay = OvertimePay + Regpay;

            SocSecTax = Pay * .06;

            FederalTax = Pay * .14;

            StateTax = Pay * .05;

            UnionDues = 10;

            AllTaxes = SocSecTax + FederalTax + StateTax + UnionDues;

            FinalPay = Pay -= AllTaxes;

            System.out.println("Your pay this week will be " + FinalPay);
            {


                System.out.println("How many Dependants:");
                Dependants = reader.nextInt();

                if (Dependants >= 3) {
                    Dependants = Pay + 35;
                    System.out.println("Your Pay is:" + Dependants);
                } else if (Dependants < 3) {

                    System.out.println("Your Pay is:" + Pay);
                }

            }

            System.out.println("Again???  Press 1 to run again and 0 to exit");
            runAgain = reader.nextInt();

        }
    }

}
