I added some format.

Who is supposed to read this?
Please use some imports. Eclipse and/or Netbeans will guide you in this.

It works when some false characters are removed from the coding - don't know if that did happen while C&P this.

Java
package mini;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ButtonGroup;
