morphingMovie.java code---help

[yeah]

I'm writing a java assignment which is to make a movie of morphing pictures.
below is what I wrote,however, it didn't work out.
anybody could help me please?

public class MorphingMovie
{
  public static void main(String[] args)
  {
    //Get the starting picture and ending picture for the morphing
    String fileName1=FileChooser.pickAFile();
    Picture startPicture=new Picture(fileName1); 
    String fileName2=FileChooser.pickAFile();
    Picture endPicture=new Picture(fileName2);
    
    /**If the starting picture and ending picture are not the same size, 
      * print an error message and do not proceed with the rest of the program
      */
    if(!(startPicture.getWidth()==endPicture.getWidth()&&startPicture.getHeight()==endPicture.getHeight()))
    {
      SimpleOutput.showInformation("Error-The two pictures chosen are not in the same size, please choose two pictues in same size");
    }
    
    else
    {
      
      //Input the number of intermediate stages for the morphing from the user 
      int numStages=SimpleInput.getIntNumber("Enter integer number of intermediate stages to morph");
      
      //Input the name of the directory in which to store the movie
      String directory=SimpleInput.getString("Enter the directory where to store the movie");
      
      //Create an array of Picture objects that will hold the sequence of pictures for the morphing
      Picture[] pictureSequence=new Picture[numStages+2];
      
      //Store the starting and ending pictures in the array.
      pictureSequence[0]=startPicture;
      pictureSequence[pictureSequence.length-1]=endPicture;
      
      //Create intermediate pictures in the array
      for(int k=1;k<pictureSequence.length-1;k++)
      {
        Picture intermediate=startPicture;
        intermediate.morphStage(startPicture,endPicture,numStages,k);
        pictureSequence[k]=intermediate;
      }
      
      //Create the first morphing movie
      FrameSequencer frameSequencer = new FrameSequencer(directory); 
      for (int i = 0; i < pictureSequence.length; i++) 
      {
        frameSequencer.addFrame(pictureSequence[i]); 
      }
      
      //Play the movie 
      MoviePlayer movie1=new MoviePlayer(directory);
      movie1.playMovie(numStages);
    }
  }
}

P.S. You didn't tell us what the problem was!

[yeah]

sorry i'm new here, don't know how to use tags; btw, the problem is the frame pictures are not pictureSequencer[k],but all startPicture.

Does morphStage() return something or is the return type void? If if returns something, then perhaps you just aren't saving it.

Also, Picture intermediate=startPicture;

If I understand this line, it means every single frame is morphed from the starting frame rather than the frame before? Wouldn't you start with the start frame, but then work from startFrame+1 and so on? No idea how that method works.
