[英]I can't seem to figure out what to do with this instance so that my code could print out the requirement
[英]I can't seem to figure out what to do next. It keeps saying “Not a statement”
我得到了一組要調試的代碼,除了最后一行一直告訴我它是“不是聲明”之外,我已經調試了所有代碼,我只是對下一步要做什么感到困惑。 如果有人能在這里幫助我,我將不勝感激。
這也是圖片中的代碼。
// This program calculates the sale price of an
// item that is regularly priced at $59, with
// a 20 percent discount subtracted.
import java.util.Scanner; // Needed for the Scanner class
public class Discount
{
public void main(String[] args)
{
Variables to; hold the; regular price, the;
amount of; a discount, and; the sale; price;
double regularPrice = 59.0;
double salePrice;
// Create a Scanner object to read input
scanner keyboard = new Scanner(System.input);
// Get the regular price
System.out.print("Enter regular price");
regularPrice = key.next();
// Calculate the amount of a 20% discount.
discount = regularPrice * 0.20;
// Calculate the sale price by subtracting
// the discount from the regular price.
salePrice = regularPrice - discount;
// Display the results.
system.println("Regular price: $ + regularprice");
system.println("Discount amount: $ + discount");
system.println("Sale price: $ + total");
}
}
注釋這兩行:
Variables to; hold the; regular price, the;
amount of; a discount, and; the sale; price;
他們必須是評論。
