如何将文本文件中的数字相乘？ [英] How do I multiply numbers from a text file together ?

问题描述

我目前正在尝试编写一个程序，通过扫描程序读取文本文件，在文本文件中，它有人名，他们销售的产品以及销售产品的数量，我需要程序来读取文本文件并将每个人的数字相乘并打印总数，我正在努力将数字乘以数字。我目前的代码是

I am currently trying to write a program which reads a text file through a Scanner and on the text file it has peoples names, products they sold and how much they sold products for, and I need the program to read the text file and multiply the numbers together for each person and print the total and I am struggling with how id multiply the numbers together. My current code is

Import java.util.Scanner;
/**

*/
public class PractiseSplit {
    public static void main(String[] args) {
        Scanner Scan = new Scanner (NumberCount.class.getResourceAsStream("pay.txt
        //Scan.useDelimiter(" ^([A-Za-z]+)\\s([0-9]+)\\s([0-9]+)$ ");
        String [] Emma = Scan.split("A-Z
        
        System.out.println("Thes in the String are ");
        while (Scan.hasNext())
        {
            String temp = Scan.next();
            System.out.println(temp);
        }
    
    }
    
}

不确定我是否采取了最好的方式，但可以任何人给我示例代码或指出我哪里出错

谢谢

推荐答案

）;
String [] Emma = Scan.split（ AZ

System.out.println（ 字符串中的内容为）;
while （Scan.hasNext（））
{
String temp = Scan.next（）;
System.out .println（temp）;
}

}

}

"); String [] Emma = Scan.split("A-Z System.out.println("Thes in the String are "); while (Scan.hasNext()) { String temp = Scan.next(); System.out.println(temp); } } }

不确定我是否会去最好的方式，但任何人都可以给我示例代码或指出我出错的地方
