Hello everyone,
I create a program that place random image in grid layout format.
The size of the grid layout is 6 x 6 = 36.
Only 10 were filled with images (each image was different) and the rest were empty.

How can I save it to a file and read it again, so it will display the same images with same placement on the grid?
Here is the code that I used to save the images:
//image file
String []arrPic = {"pic1.jpg","pic2.jpg","pic3.jpg","pic4.jpg","pic5.jpg","pic6.jpg","pic7.jpg","pic8.jpg","pic9.jpg","pic10.jpg",,"pic11.jpg","pic12.jpg","pic13.jpg"};
ArrayList<String> pictures = new ArrayList<String>(Arrays.asList(arrPic));
ArrayList<String> file = new ArrayList<String>();
JPanel pDraw = new JPanel(new GridLayout(6,6,2,2));
...
//fill all grids with empty label
for (int i =0; i<(6*6); i++){
JLabel lbl = new JLabel("");
pDraw.add(lbl);
}
...
//Choose random box to be filled with images
for(int i=0; i<10; i++){
Boolean number = true;
while(number){
int n = rand.nextInt(35);
if(!(arraylist.contains(n)))
number = false;
arraylist.add(n);
}
//fill the grids with images
for(int i=0; i<arraylist.size(); i++){
//select random image from arraylist
int index = rand.nextInt (pictures.size());
String fileName = (String) pictures.get(index );
//find the image file
icon = createImageIcon(fileName);
//save the file in a new file
file.add(fileName);
//rescaled the image
int x = rand.nextInt(50)+50;
int y = rand.nextInt(50)+50;
Image image = icon.getImage().getScaledInstance(x,y,Image.SCALE_SMOOTH);
icon.setImage(image);
//remove empty label and replace it with an image
int one = (Integer) arraylist.get(i);
pDraw.remove(one);
final JLabel label;
pDraw.add(label,one);
}
