Question

Can you help me to load or read multiple images from a file. Because I know read them but How to read single file from a file but how to read multiple images. And I do not know how I would download them all from a specific folder.

For example:

// Atributes

protected BufferedImage imag1;
protected BufferedImage imag2;
protected BufferedImage imag3;
protected BufferedImage imag4;

//Konstructor

public GeneralTurtle(JFrame myForm) 
{
    poc =0;
    this.myForm=myForm;
    color= Color.BLACK;

    try //loading images from file turtles
    {
    imag1 = ImageIO.read(new File("hore.png"));
    imag2 = ImageIO.read(new File("dole.png"));
    imag3 = ImageIO.read(new File("vlavo.png"));
    imag4 = ImageIO.read(new File("vpravo.png"));

But I do not know how I would solve it better when I have more pictures. Because this would be laborious and inefficient.

So you say you have a folder….

You can do this:

File path = new File("MyFilesFolder");
List imageCollection = new ArrayList();
File [] files = path.listFiles();
for (int i = 0; i < files.length; i++){
    if (files[i].isFile()){ //this line weeds out other directories/folders
        imageCollection.add(loadImage(files[i]));
    }
}

For the images you can use some Collection to load them in.

I take the assumption that you can work out the loadImage(File file) method.
And if you have other files then images in that folder you better read up on FileFilter.
