我的程序出现代码输出问题。更新了新的蒲式耳篮类

Question

（现在有更新的代码）在尝试从我的程序中获取正确的输出时遇到严重问题。我需要从这个程序得到一个特定的输出，它应该是这个输出：

Rick...
This bushel basket has 0 apples in it.
This bushel basket has 33 apples in it.
This bushel basket has 29 apples in it.
This bushel basket has 0 apples in it.
Newt...
This bushel basket has 100 apples in it.
false
false
100
25
Michele...
true
false
false
false
false
true
Herman...
This bushel basket has 0 apples in it.
Jon...
This bushel basket has 125 apples in it.
Ron...
This bushel basket has 20 apples in it.
This bushel basket has 0 apples in it.
This bushel basket has 125 apples in it.
Gary...
This bushel basket has 0 apples in it.

但是我收到了输出：

Rick...
This bushel basket has 0 apples in it.
This bushel basket has 33 apples in it.
This bushel basket has 29 apples in it.
This bushel basket has 0 apples in it.
Newt...
This bushel basket has 100 apples in it.
false
false
100(THIS IS WHERE THE BAD OUTPUT STARTS)
true
Michele...

Herman...
This bushel basket has -5 apples in it.
Jon...
This bushel basket has 300 apples in it.
Ron...
This bushel basket has 20 apples in it.
This bushel basket has -30 apples in it.
This bushel basket has 960 apples in it.
Gary...
This bushel basket has 0 apples in it.

Answer 1

改变构造函数

BushelBasket(int apples) 
{
   if (apples < 0 )
      this.apples = 0;
   else if(apples >125)
      this.apples = 125;
   else
      this.apples=apples;
}

Answer 2

纽特

你的代码有

System.out.println( newt.getApples() );                      // integer
System.out.println( newt.roomLeftInBasket() );               // boolean

这不会像你期望的那样返回100 25，它会返回100 true

您似乎需要更改 roomLeftInBasket() 方法以返回篮子中剩余的金额，或更改代码使其看起来像：

if (newt.roomLeftInBasket())
{
  System.out.println( newt.fullBasket() - newt.getApples());
}

但您必须创建 fullBasket() 方法

赫尔曼

在 Herman 的构造函数中，你给他的篮子 -5 个苹果。如果你不能有一个否定的篮子，你将不得不改变构造函数来检查这个。

乔恩

与 Herman 相同，但您需要检查创建的篮子的价值是否大于一个完整的篮子并相应地进行更改。

罗恩

对于 Ron，您需要检查给 eat() 的值是否大于篮子中的值，并处理 Ron 尝试吃的苹果多于篮子中的苹果的情况。
