**二,实现西游记的课题案例
使用重写完成,孙悟空念经的方法（和唐僧念的经不同）**
抽象类：
package test9_6;
public abstract class Test2nianjing {
int ID;
String name;
String whatkind;
String education;
public void whostart(String kind){
System.out.println(this.name+"在开始念"+kind+"这种经");
}
public String toString(){
return "ID:\t"+this.ID+"\n 姓名：\t"+this.name+"\n念经种类：:\t"+this.whatkind+" \n 什么职业L:\t"+this.education;
}
public abstract void nianjing();
}
2、孙悟空的类
package test9_6;
public class Testnianjingsun extends Test2nianjing{
public Testnianjingsun(){
this.education="和尚";
this.ID=2;
this.name="孙悟空";
this.whatkind="假装念经";
}
public void nianjing() {
System.out.println("孙悟空来也！！！！");
this.toString();
}
}
3.孙悟空的测试类：
package test9_6;
public abstract class Test2nianjingofsun {
public static void main(String [] args){
Testnianjingsun sun=new Testnianjingsun();
sun.nianjing();
}
}
4、唐僧的继承类，复写抽象方法；
package test9_6;
public class Testnianjingtang extends Test2nianjing{
public Testnianjingtang(){
this.education="和尚";
this.ID=1;
this.name="唐僧";
this.whatkind="大悲咒+经箍咒+太平经";
}
public void nianjing() {
System.out.println("快点跑，唐僧要念经了！！！----------------");
this.toString();
}
}
5、唐僧的测试类：
package test9_6;
public abstract class Test2nianjingoftang {
public static void main(String [] args){
Testnianjingtang tang=new Testnianjingtang();
tang.nianjing();
}
}
OK做完了！初步实现，你学到什么了么？我受益匪浅那！Android很多这样的抽象类，老师说面试抽象类占到70%，以我个人经验俩说着实不假的！。。。。。
