Java 循环复制图片

我有六张照片，我需要把它们复制到一个足够大的窗口，这样它们就不会重叠，也不会留下多余的空间。我正处于需要编程showOff（）的步骤。我的任务是实例化EditablePicture的操作是

EditablePicture bigshowPict = new EditablePicture(??,??);

我需要一个循环，将数组中的图片逐个复制到可编辑的图片中

bigShowPict.copyIn(??,??,this.pictArray[??]);

其中循环计算一个或两个？？，？？找出复制图片的位置。EditablePicture类和bigShowPict方法是预定义的，不必更改。到目前为止，我所有的代码都是

House.java

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

  public House(String pString)
  {
    this.owner = pString;
  }
  public String toString()
  {
    return("The House owned by " + this.owner);
  }
  public void acquire( int i, Picture pRef )
  {
    this.pictArray[i] = 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()
  {
    int sum = 0;
    for (int i=0; i<7;i++)
    {
      sum = sum + this.pictArray[i].getWidth();
     int resultHeight=1000;
    int resultWidth = sum;
      bigShowPict.copyIn(resultWidth,resultHeight,this.pictArray[i]);
      EditablePicture bigShowPict = new EditablePicture(resultWidth,resultHeight);
      bigShowPict.show();
    }
  }
}
