在数组中显示图片

Question

在drjava中我试图获取图片，将它们保存在阵列中，然后打印出每张图片的描述。现在一切都编译但是当我运行它时，我选择包含图片的文件夹，然后交互窗格消失。我到目前为止的代码是在我的House应用程序中获取图片和打印描述

HOUSE.java

public class House
{
  String owner;
  public final static int CAPACITY = 6;
  Picture[ ] pictArray = new Picture[CAPACITY];

  public House(String pString)
  {
    this.owner = pString;
  }
  public String toString()
  {
    return("The House owned by " + this.owner);
  }
  public void acquire( int position, Picture pRef )
  {
    this.pictArray[ position ] = pRef;
  }
  public void printPictures()
  {
    for (int i=0; i < this.pictArray.length;i++)
    {
      System.out.print("The Picture in position " + i + " is ");
      System.out.println( this.pictArray[ i ]);
    }
  }
  public void swap( int positionA, int positionB )
  {
    System.out.println("NOTHING DONE.  THIS IS JUST A swap's STUB");

  }
  public void showOff()
  {
    System.out.println("NOTHING DONE.  THIS IS JUST showOff's STUB");

  }
}
