数据表MVC中的时间

Question

你好，我只想在数据表中显示时间，但是它显示[object object]这是代码

public class Toebuttons extends JButton implements ActionListener
{
boolean x = true; // if true x's turn if false o's turn
int count = 0;
public Toebuttons()
{
   super("blank");
   this.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
   if(this.x == true)
   {
       count++;
       System.out.println(count);
       setText("X");
       this.x = false;
   }
   else if(this.x == false)
   {
       count++;
       System.out.println(count);
       setText("O");
       this.x = true;
   }
  }
}
