大一Java作業(yè)題

首先回答您的do-while的問題，while中是條件為true的時(shí)候繼續(xù)執(zhí)行do里面的代碼，當(dāng)為false的時(shí)候結(jié)束執(zhí)行。下面是您的問題的一種解決辦法，忘采納。

import java.util.Scanner;

public class JuiceVendingCashFlow {

public static int total = 0;

public static int customernum =0;

public static double income = 0;

public double income (double w,double t){

income += (w/100)*3.5+t*1.5;

total++;

customernum++;

return income;

}

public static void main(String[] args) throws Exception {

JuiceVendingCashFlow f= new JuiceVendingCashFlow();

double weight = 0;

System.out.println("Customer"+"#"+ ++customernum+" welcome!");

do {

System.out.print("how much juice are you after?");

try{

Scanner s = new Scanner(System.in);

weight = s.nextDouble();

if(weight0) {

throw new Exception();

}

} catch (Exception e) {

System.out.println("OVER");

}

if (weight=0) {

System.out.println("how many toppings would you like?");

Scanner b = new Scanner(System.in);

double topping = b.nextDouble();

f.income(weight, topping);

}

} while (weight=0);

System.out.println(income+" "+ --customernum);

}

}

此方法寫的倉促其中如果topping為負(fù)值的時(shí)候會(huì)出現(xiàn)異常，您可以寫一個(gè)異常拋出來解決問題。
