Question

我刚刚开始自学Java，但我坚持这个，所以你能解释一下这是如何工作的吗？这是练习：

在本练习中，Ze将询问您 Zomatoes 的数量    Zinions 你想买。

您必须在[A-Za-z]范围内输入ASCII字符。   您想要购买的Zomatoes数量将在一个   名为zomatoes的变量，类型为char。

您要购买的Zinions的数量将以a。的形式提供给您   名为zinions的变量，其类型为char。

您必须添加两个char变量的ASCII值（zomatoes   和zinions）并填充名为items的变量   输入int，加上总和。

例如，如果您要求a Zomatoes和C Zinions，则总数   项目数为a(97) + C(67) = 164

这是他们给我的代码：

public class CrazyConverter { 

    public static void main(String args[]) {         
        Scanner scanner = new Scanner(System.in); 
        System.out.println("Hello I am your friendly grocer Darth: "); 
        System.out.println("How many zomatoes do you want ? (Enter a character in the range [A-Za-z]): "); 
        String sZomatoes = scanner.nextLine(); 
        System.out.println("How many zinions do you want ? (Enter a character in the range [A-Za-z]): "); 
        String sZinions = scanner.nextLine(); 

        char zomatoes = sZomatoes.charAt(0); 
        char zinions = sZinions.charAt(0); 
        int  items = 0; 
        sZomatoes= 65;
        ///{ 

   char zinions=(char) asciiValue;

                //start your coding here  

                //end

        ///} 

        System.out.println("Thank you ! you have asked for " + items + " items"); 
    } 
}

Answer 1

好像是作业。

     char zomatoes = sZomatoes.charAt(0);//storing character for zomatoes 
     char zinions = sZinions.charAt(0); //storing character for zinions
     int  items = zomatoes+zinions;//Adding the ascii value of both zomatoes and zinions.

我已经给你提示了。希望你能纠正代码中的错误。

Answer 2

您忘了将char（s）加在一起并初始化items。我想你想要的东西，

char zomatoes = sZomatoes.charAt(0);
char zinions = sZinions.charAt(0);
int items = zomatoes + zinions;
System.out.printf("The total number of items is '%s'(%d) + '%s'(%d) = %d%n",
        zomatoes, (int) zomatoes, zinions, (int) zinions, items);

当我用你的样本输入

运行它时

Hello I am your friendly grocer Darth: 
How many zomatoes do you want ? (Enter a character in the range [A-Za-z]): 
a
How many zinions do you want ? (Enter a character in the range [A-Za-z]): 
C
The total number of items is 'a'(97) + 'C'(67) = 164

添加2个char变量的ASCII值
