shark.zd.继承

对于继承的编程理解 （参考JAVA编程百例）

其中osier函数

 

package shark.zd.继承;

public class osier extends tree{
    public void leaf(){
        super.leaf();
        String sharp ="方形";
        super.print("叶的形状："+sharp);
    }
    public void flower(){
        print("哈哈树没有花");
        
    }
    public static void main(String[] ages){
        
        osier o = new osier();
        o.print("柳树的根：");
        o.root();
        o.print("柳树的干");
        o.bolo();
        o.print("柳树的枝：");
        o.branch();
        o.print("柳树的叶：");
        o.leaf();
        o.print("柳树的花");
        o.flower();
        
    
        
    }

}


tree函数

 

package shark.zd.继承;

public class tree {
    public void root(){
        String sSite = "地下";
        String sFunction = "吸收土样";
        print("位置:"+sSite);
        print("功能"+sFunction);
        
    }
    public void bolo(){
        String sSite="地上";
        String sFunction="传递养分";
        print("位置："+sSite);
        print("功能："+sFunction);
        
    }
    public void branch(){
        String sSite="树干上";
        String sFunction="吸收养分";
        print("位置："+sSite);
        print("功能："+sFunction);
        
    }
    public void leaf(){
        String sSite ="树枝上";
        String sFunction="光合作用";
        String sColor = "绿色";
        print("位置"+sSite);
        print("功能："+sFunction);
        print("颜色："+sColor);
    }
    public void print(Object sPara) {
        // TODO Auto-generated method stub

        System.out.println(sPara);
        
    }
    

}
