为什么我的堆栈要求输入但是在第二次迭代之前不接受任何输入？

Question

我似乎无法用我制作的堆栈解决这个问题。我为堆栈设置了一个大小，然后是第一个＆＃34; push＆＃34;总是空白的，只是越过用户输入点。然而第二次迭代停止并等待用户输入。为什么第一次迭代不会停止用户输入？怀疑for循环是错误的......也许是push方法？

import java.util.Scanner;

public class myApp
{
public static void main(String[] args)
                       throws stackOutOfBounds
{
  //Variable declarations
     Scanner kbd = new Scanner(System.in);
     String name;
     int maxSize;


  //Prompts user to enter size of "shopping list" as well as name
  System.out.println("What will be the name of your stack?");
  name = kbd.nextLine();
  System.out.println("How many items will you be putting on your stack?");
  maxSize = kbd.nextInt();



  //Sets name and size
  MyStackADT Stack = new MyStackADT(name, maxSize);
  System.out.println();

  //prompts user to add Strings to shopping list
  for(int y = 0; y <= maxSize; y++)    
  {
  System.out.println("What will you be buying today?");
  Stack.push(kbd.nextLine());
  System.out.println("");
  }

   //Outputs shopping list
  System.out.println(Stack);

  //Outputs size of list
  System.out.println("The size of the stack " + Stack.size());
  System.out.println("The top of the stack is " + Stack.top());


  }
  }

然后输出看起来像这样......

What will be the name of your stack?
Monday

How many items will you be putting on your stack?
2

What will you be buying today?

What will you be buying today?
eggs
What will you be buying today?
milk
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
 at MyStackADT.push(MyStackADT.java:24)
 at myApp.main(myApp.java:30)

我需要改变for循环还是push方法？任何建议都会很棒。
