Adding Buttons to an Array
I have 208 Buttons and I want to assign numbers to them by using an array. These buttons have different images on top of them and I want them to appear on the screen when I put the according number, which represents the Button on the screen. The 2D Array can be ignored. I know that I have to get rid of this code and write code for the array in the place of this one, but I can't figure what I have to do.

It looks like you want to create a grid of Images held by buttons. If so, then simply create your 2-dimensional array of JButton, don't give the buttons names, and create your JButtons in a for loop, adding them to the array and to the GridLayout-using JPanel at the same time. You can then use the same grid to assign ImageIcons for each button.
Your map should be held by a text file, not hard-coded in your code, and you can then read the map into its own 2D array, and use this as the basis for creating and iterating through your button grid.
e.g.,
// first read in the text file and fill the map 2D int array
for (int row = 0; row < btnGrid.length; row++) {
for (int col = 0; col < btnGrid[row].length; col++) {
int value = map[row][col]; // holds value for icons array
Icon icon = icons[value]; // an array of ImageIcons
btnGrid[row][col] = new JButton(icon);
btnGrid[row][col].addActionListener(someListener);
btnPanel.add(btnGrid[row][col]);
}
}
In the JButton's Action or ActionListener (here noted as someListener), you'd change the state of the button, perhaps its icon, on button press, depending on your need.
