Question

我已经编写了下面的代码，现在我需要对其进行编辑，以便显示超过3000的结帐号码。即必须显示：

以下结帐时间超过3000.00磅：结帐编号“元素编号” 结帐编号“元素编号”等

我一直在尝试一些不同的方法但尚未成功。谢谢你的帮助！

import java.util.Scanner;
public class Checkouts
{
   static final int NUMBER_OF_CHECKOUTS = 6, MAX_TAKING = 1000000;

   public static void main(String[] args)
   {
      Scanner scan = new Scanner(System.in);
      double[] checkoutList = new double[NUMBER_OF_CHECKOUTS];

  System.out.println();
  for (int index = 0; index < checkoutList.length; index++)
  {
     System.out.print("\tEnter takings for checkout number ");
     System.out.print((index + 1) + ": ");
     checkoutList[index] = scan.nextDouble();
     while (checkoutList[index] < 0 || checkoutList[index] > MAX_TAKING)
     {
        System.out.print("\tImpossible! - enter takings for checkout number ");
        System.out.print((index + 1) + " again: ");
        checkoutList[index] = scan.nextDouble();
     } 
  }
  System.out.println();
  double totalTakings = 0;
  for (int index = 0; index < checkoutList.length; index++)
  {
     totalTakings += checkoutList[index];
  }

  System.out.println("The total takings for the supermarket is " + totalTakings );

} }

由于你已经有一个遍历每个索引的for循环，我们可以在那里进行检查：
