java 计算空格_获取 - 在java中，获取由空格分隔的两个数据并计算_java_酷徒编程知识库...

我的问题是，想输入两个由空格分隔的数字，得到这两个数，然后计算这两个数，10 *20 =200.

我的GETTER和SETTER类import java.util.*;

public class LabExer2

{

private String itemName;

private double itemPrice;

private int itemQuantity;

private double amountDue;

public void setItemName(String newItemName)

{

itemName = newItemName;

}

public String getItemName()

{

return itemName;

}

public void setTotalCost(int quantity, double price)

{

itemQuantity = quantity;

itemPrice = price;

amountDue = itemQuantity * itemPrice;

}

public double getTotalCost()

{

return amountDue;

}

public void readInput()

{

Scanner s = new Scanner(System.in);

System.out.println("Enter the name of the item you are purchasing.");

itemName = s.nextLine();

System.out.println("Enter the quantity and price separated by a space.");

//itemQuantity = s.nextInt();

//itemPrice = s.nextDouble();

}

public void writeInput()

{

System.out.println("You are purchasing" + itemQuantity +"" + itemName +"(s) at" + itemPrice +" each.");

System.out.println("Amount due is" + getTotalCost());

}

}

public class MainLabExer2

{

public static void main(String[]args)

{

LabExer2 le = new LabExer2();

//still not finished because I can't figure out the process in the other class.

}

}

我想要的输出：

输入要购买的物料的名称，

pencil

输入用空格分隔的数量和价格，

3 15.50

购买3支铅笔，每支价格为15.50.

金额为46.50

不知道使用什么东西，我是java的初学者。
