java中的抽象类

代码实现

Telphone.java

package com.imooc;  public abstract class @H_360_58@Telphone {     public abstract void call();     public abstract void message(); } 

/javaDemo5/src/com/imooc/CellPhone.java

package com.imooc;  public class CellPhone extends Telphone {      public void call() {         // TODO Auto-generated method stub         System.out.PRintln("通过键盘来打电话");     }      public void message() {         // TODO Auto-generated method stub         System.out.println("通过键盘来打短信");     }  } 

SmartPhone.java

package com.imooc;  public class SmartPhone extends Telphone {      public void call() {         // TODO Auto-generated method stub         System.out.println("通过语音来打电话");     }      public void message() {         // TODO Auto-generated method stub         System.out.println("通过语音来发短信");     }  } 

/javaDemo5/src/com/imooc/InITail.java

package com.imooc;  public class Initail {      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();     }  }
