如何按顺序打印年份声明？ [英] How do I print the year statement in order?

问题描述

import java.util.Scanner; // program uses class Scanner
public class SellingPrice {
	public static void main (String [] agrs) {
		//create Scanner object to read inputs 
		Scanner input = new Scanner (System.in);
		
		//initialization phase
		int salesRevenue = 0; //initialize sales revenue 
		int productsSold = 0; //initialize # of products sold 
		
		System.out.println();
		System.out.print("Please press -1 + Enter two times to display the calculation!");
		System.out.println();
		

		//prompt for input - sales revenue and # of product
		System.out.printf("Enter the sales revenue for year or -1 to quit: ");
		int saleNumbers = input.nextInt();
	
		System.out.print("Enter a total number of products sold or -1 to quit: ");
		int productNumbers = input.nextInt();
	

		while (saleNumbers != -1 && productNumbers != -1){
			salesRevenue = salesRevenue + saleNumbers;
			productsSold = productsSold + productNumbers;
			
			//prompt for another input
			System.out.print("Enter the sales revenue for each year or -1 to quit: ");
			saleNumbers = input.nextInt();
			System.out.print("Enter a total number of products sold or -1 to quit: ");
			productNumbers = input.nextInt();
		}//end while
	
		
		if (salesRevenue != 0 && productsSold != 0){
			double totalPrice = ((double) salesRevenue / productsSold);
			System.out.printf("Selling price for the first year is $ %d%n", saleNumbers);
			System.out.printf("Total sales revenue is $%d%n", salesRevenue);
			System.out.printf("Total number of products sold is %d%n", productsSold);
			System.out.printf("Combined selling price is $%.2f%n", totalPrice);
		}
		else {
			System.out.print("No inputs were entered!");
		}
	}
}

这是我的Java代码到目前为止，我的问题是我不知道如何按照我的预期显示年份。我让其他的东西工作得很好，但我不能显示年份（第1年和第2年）。我被允许只使用For循环和While循环，没有数组。请帮我。

这应该是结果



例如;第一年销售收入为1000，产品总销售数量为10，第二年销售收入为2000，销售产品总数为10）（我们假设用户输入两个输入）



打印：



第一年的销售价格是$ 100.00（1000/10）

第二年的销售价格为$ 200.00（2000/10）

总销售收入为$ 3000.00（1000 + 2000）

销售的产品总数为20.00（ 10 + 10）

合并售价为$ 150.00（3000/20）



我的尝试：



我尝试使用不同的循环和字面上的一切，我重写了很多次。我现在很困惑。我只允许使用For循环，While循环和Sentinel循环。

This is my Java code so far, my problem is I don't know how to display the year as I expected. I got the other things work just fine but I can't display the year (1st year and 2nd year). I'm allowed to use For loop and While loop only, no arrays. Please help me.
This should be the result

For example; for the first-year sales revenue is 1000, the total number of products sold 10, for the second-year sales revenue is 2000, the total number of products sold 10) (we are assuming that user enters two inputs)

It will print:

Selling price for the first year is $100.00 (1000/10)
Selling price for the second year is $200.00 (2000/10)
Total sales revenue is $3000.00 (1000+2000)
Total number of products sold is 20.00 (10+10)
Combined selling price is $150.00 (3000/20)

What I have tried:

I tried using different loops and literally everything, I rewrote everything a bunch of times. I'm confusing right now. I'm allowed to use For loop, While loop and Sentinel loop only.

推荐答案

％d％n，saleNumbers）;
System.out.printf（ 总销售收入

%d%n", saleNumbers); System.out.printf("Total sales revenue is

％d％n ，salesRevenue）;
System.out.printf（ 销售的产品总数为％d％n，productsSold）;
System.out.printf（ 组合销售价格是

%d%n", salesRevenue); System.out.printf("Total number of products sold is %d%n", productsSold); System.out.printf("Combined selling price is

％。2f％n，totalPrice）;
}
else {
System.out.print（ 未输入任何输入！）;
}
}
}

%.2f%n", totalPrice); } else { System.out.print("No inputs were entered!"); } } }

这是我的Java代码到目前为止，我的问题是我不知道我不知道如何按照我的预期来展示这一年。我得到了其他的工作就好了，但我无法显示年份（第1年和第2年）。我被允许只使用For循环和While循环，没有数组。请帮我。
