1.定义一个模板的抽象类House,里面有模板抽象方法

2.定义一个实现模板类LargeBuilding，该类继承House,重写House的模板抽象方法

3.测试，多态

1.

public abstract class House {public abstract void function();public void Getfunction(){    System.out.println("模板房子前");    function();    System.out.println("模板房子后");}}

2.

//大厦public class LargeBuilding extends House{
        @Override    public void function() {    System.out.println("大厦办公");    }}//餐厅public class Restaurant extends House {
        @Override    public void function() {        System.out.println("餐厅吃饭");    }}

3.

public class Test {public static void main(String[] args) {    House House1=new LargeBuilding();    House House2=new Restaurant();    House1.Getfunction();    System.out.println("--------------");    House2.Getfunction();}}输出：模板房子前大厦办公模板房子后--------------模板房子前大厦办公模板房子后
