Random named instances

Question

If for example I was to create a program that added buttons at certain time intervals (and this process could occur forever - i.e. keep adding a button every 30 seconds until the window is closed), and these buttons had ActionListeners attached, meaning they needed to have different names - how would I make it so it would create button1, button2.....buttonx
What I mean is how would I do JButton buttoni = new Jbutton(i)
With i being an incrementing integer.

Answer 1

they don't need different names. the variable you declare as a JButton isn't the JButton, it's just a pointer to it. you can happily just call new JButton forever without assigning the result to anything, or you can assign the result to the same variable over and over. the other JButtons will still exist, and you can get hold of them when you need to via the actionListener. they can all use the same actionListener, too, if you want
for(int i = 0; i < 10; i++) {
   JButton button = new JButton();
   button.addActionListener(this); // or however you want to add it
   // add to your container here, however you like
}one variable. ten buttons. whenever actionPerformed is invoked, you can get hold of the right button from the event
