public void actionPerformed(ActionEvent e) {
for (int i = 0; i < button.length; i++) {
for (int j = 0; j < button[i].length; j++) {
if (e.getSource() == button[i][j]) {
if (b.getBoard()[i][j] instanceof Atom) {
deletA(x, y);

x = i;
y = j;

appearA(x, y);
} else {
if (b.getBoard()[i][j] instanceof Free) {
if (i == x && (j - 1) == y) {
b.move(b.getBoard()[x][y], 'R');
} else if (y == j && (i + 1) == x) {
b.move(b.getBoard()[x][y], 'U');
} else if (i == x && (j + 1) == y) {
b.move(b.getBoard()[x][y], 'L');
} else if (y == j && (i - 1) == x) {
b.move(b.getBoard()[x][y], 'D');




i make an atomic game and create the board by 2 D array and i need when i click at the atom then to click on the free space the atom and the free space will swap each other

What problem(s) are you having with your code so far?

Do you have a program that compiles yet? If not, make one, compile it and come back with questions about the errors.

When it compiles, try executing it and come back when you have questions about errors.

i just want to change the code function to swap the two cells together

Sorry, I don't understand what you mean by

Can you give an example of the data before and after the swap?

Which line(s) of code you posted are you talking about?
