如何更改代码以使程序在用户输入否之后跳过选项？

Question

我希望该程序跳过“输入另一个？”？当提示“明确”后输入n时。我该怎么做？ 现在，当输入n时，它仍然会提示“长距离？”

以下是当前一批代码。 上下文：这是代码的数据输入部分，其中用户输入被添加到arraylist。

String input=null;
    
    //data entry (user input + adding to arraylist)
    do {
    
        System.out.println("Enter parcel code: ");
        String pCode=kboard.next();
        
        System.out.println("Enter parcel length: ");
        double pLength=kboard.nextDouble();
        
        System.out.println("Enter parcel width: ");
        double pWidth=kboard.nextDouble();
        
        System.out.println("Enter parcel height: ");
        double pHeight=kboard.nextDouble();
        
        System.out.println("Enter parcel weight: ");
        double pWeight=kboard.nextDouble();
        
        Parcel parcel=new Parcel(pCode, pLength, pWidth, pHeight, pWeight);
        
        List.add(parcel);
        
        System.out.println("Express parcel? Y/N: ");
        String expressP=kboard.nextLine();
        input=kboard.next();
        
        System.out.println("Long distance parcel? Y/N: ");
        String longDist=kboard.nextLine();
        input=kboard.next();
        
        System.out.println("Do you want to enter another parcel record? Y/N: ");
        input=kboard.next();
        
    }
    
    while (input.toLowerCase().equals("y"));

Answer 1

在接受' express包裹'的输入后，使用' if-else '条件

   System.out.println("Express parcel? Y/N: ");
   String expressP=kboard.nextLine();
   input=kboard.next();

   if(ip.equalsIgnoreCase("Y").  //This will execute only if previous resp is Yes
  { 
       System.out.println("Long distance parcel? Y/N: ");
       String longDist=kboard.nextLine();
      input=kboard.next();
  }

  System.out.println("Do you want to enter another parcel record? Y/N: ");
  input=kboard.next();

，如果用户输入n或n，则会要求下一个迭代跳过包裹代码距离。

尝试以下代码：

  String input=null;

    //data entry (user input + adding to arraylist)
    do {

        System.out.println("Enter parcel code: ");
        String pCode=kboard.next();

        System.out.println("Enter parcel length: ");
        double pLength=kboard.nextDouble();

        System.out.println("Enter parcel width: ");
        double pWidth=kboard.nextDouble();

        System.out.println("Enter parcel height: ");
        double pHeight=kboard.nextDouble();

        System.out.println("Enter parcel weight: ");
        double pWeight=kboard.nextDouble();

        /*Parcel parcel=new Parcel(pCode, pLength, pWidth, pHeight, pWeight);

        List.add(parcel);*/

        System.out.println("Express parcel? Y/N: ");
        String expressP=kboard.next();
        if (expressP.equalsIgnoreCase("Y")) {

            System.out.println("Long distance parcel? Y/N: ");
            String longDist = kboard.nextLine();
            input = kboard.next();
        }
        System.out.println("Do you want to enter another parcel record? Y/N: ");
        input=kboard.next();

    }

    while (input.toLowerCase().equals("y"));

如果检查用户已输入y，则需要添加额外的代码
