为什么我的大括号总是错！

package interfacetest;

public class TelphoneTest {
 public static void main(String[] args) {
  Telephone tel1 = new CellPhone();
  tel1.call();
  tel1.message();
  Telephone tel2 = new SmartPhone();
  tel2.call();
  tel2.message();
  
  
  IPlayGame ip1 = new SmartPhone();
  ip1.PlayGame();
  IPlayGame ip2 = new Psp();
  ip2.PlayGame();
  
  IPlayGame ip3 = new IPlayGame(){

   @Override
   public void PlayGame() {
    // TODO Auto-generated method stub
   System.out.println("使用匿名内部类的方式");
   }
   
  }
 }
}
