我有一个JOptionPane,是的,没有按钮.但是,无论你点击它的哪个按钮仍然存在.救命!下面是代码:

int dialogButton = JOptionPane.YES_NO_OPTION;
            JOptionPane.showConfirmDialog (null, "Are you sure?","WARNING", dialogButton);
            if(dialogButton == JOptionPane.YES_OPTION) {
                System.exit(0);
            if(dialogButton == JOptionPane.NO_OPTION) {
                  remove(dialogButton);
                }
              }
