Randomly written numbers in a game using java.util.Random
0
Here is my code.
I would like the window to look like this but I don't like the numbers to be written 1-36 like in this code. When I delete that code and try with:
Random r = new Random();
for(int k = 0; k < z; k++) {
and I define z=20; that field that was in the first place with 1-36 number, is deleted.
My expected output is, to be a field like in the code below but the numbers to be different every time I open the game.
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(new GridLayout(1, 2, 1, 1));
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(2, 1, 1, 1));
frame.add(panel, BorderLayout.CENTER);
JPanel center = new JPanel();
center.setLayout(new GridLayout(9, 9, 1, 1));
int z = 0;
for(int i = 0; i < 6; i++) {
for(int j = 0; j < 6; j++) {
JButton button = new JButton(Integer.toString(++z));
center.add(button);
}
}
frame.add(center, BorderLayout.CENTER);
frame.setVisible(true);

I don't understand your question - I don't see anyRandomin your code, and it's not clear how your proposed change would fit in there, and what you expect to happen

Can the numbers be duplicated? Like 6-8-12-6-12 ... Or do they just have in a random order? Which would actually means a permutation of the numbers between 1 and 36

Random is old and not very random. I would suggest to useSecureRandominstead. SecureRandom's interface is also more convenient.

I was thinking the numbers to be duplicated like I give a limitation that i want them to be from 1-6 and only those numbers show in the 36 cubes.

Are you saying you want randoms without duplicates? Kind of hard to understand what you're trying to do...

You can use a method that will add random numbers in the indicated range as the names to your buttons. Somthng like this:
public class Frame {
public static void main(String args) {
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(new GridLayout(1, 2, 1, 1));
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(2, 1, 1, 1));
frame.add(panel, BorderLayout.CENTER);
JPanel center = new JPanel();
center.setLayout(new GridLayout(9, 9, 1, 1));
for(int i = 0; i < 6; i++) {
for(int j = 0; j < 6; j++) {
JButton button = new JButton(Integer.toString(random(1, 6)));
center.add(button);
}
}
frame.add(center, BorderLayout.CENTER);
frame.setVisible(true);
}
private static int random(int min, int max) {
return (int) (Math.random() * (max - min) + min);
}
}
