java继承重写super关键字用法

父类
package 继承2;
//植物
public class Botany {
public double height;
public int age;
public Double getHeight() {

 return height;

}
public void setHeight(double height){
this.height = height;

}

public int getAge(){
return age;
}
public void setage(int age){
this.age = age;
}
public Botany(double height,int age){
this.height=height;
this.age=age;
}
public void eat(){
System.out.println(“牡丹花很香很香”);
}
}

子类
package 继承2;

public class Peony extends Botany {
public void color(){
System.out.println(“牡丹花的颜色:红色”);

     }
     public void behavior(){
    	 System.out.println("牡丹花在光合作用");
     }
     public void fragrance(){
    	 System.out.println("很香很香的花");
    	 }
     
     public Peony(double height,int age){
    	 super(height,age);
     }

}

测试类

package 继承2;

public class TestPeony {
public static void main(String[] args){
Peony d= new Peony(150,3);
System.out.println(“牡丹花的高度为”+d.getHeight()+“cm”);
System.out.println(“牡丹花的年龄为：”+d.getAge()+“岁”);
d.behavior();
d.color();
d.fragrance();
}
}

结果
