I had created a JOptionPane of type showInputDialog. When it opens it, it shows me two buttons: OK and Cancel. I would like to handle the action when I push on Cancel button, but I don't know how to reach it. How can I get it?

You could do it like this:

String val = JOptionPane.showInputDialog("Value: ");
if(val == null){
  // nothing goes here if yo don't want any action when canceled, or
  // redirect it to a cancel page if needed
}else{
  //insert your code if ok pressed
  // JOptionPane return an String, as you was talking about int
  int value = Integer.ParseInt(val);
}

showInputDialog return NULL if you click cancel and String object even if it's empty. So all you need to do is test if it's Null and if it's not empty.
