在inital类里 IPlayGame ip1 = new SmartPhone();报错
public class Initial {
 public static void main(String[] args) {
  // TODO Auto-generated method stub
    Telphone tel1 =new Cellphone(); 
    tel1.call();
    tel1.message();
    Telphone tel2 =new Smartphone();
    tel2.call();
    tel2.message();
    
    IPlayGame ip1 = new Smartphone();
    IPlayGame ip2 =new Psp();
   
   }
}
你写的太简洁了,报的什么错,还有其余的代码怎么写的....才能判断
