Question

帮我做一下这道JAVA题，急！！！

建一个抽象类Food，在该类中建一个抽象方法taste（）和一个公有属性weight；再建一个类Cake，它继承Food，在该类中写一个方法覆盖父类的taste（）方法，在该方法中输出Cake类的weight属性值。并建一个具有一个weight参数的构造方法；再建一个类Banana，它也继承Food类，并也在该类中写一个方法覆盖父类的taste（）方法，在该方法中输出Banana类的weight属性值。再建一个TestFood类，在该类的main方法中分别创建一个Cake和Banana的实例，并调用它们的taste方法进行输出

Answer 1

//food 抽象类
package food;
public abstract class Food {
int weight;
abstract void taste();
}
//cake类继承food，实现food类的抽象方法
package food;
public class Cake extends Food{
//Cake 构造方法
public Cake(int weight) {
this.weight=weight;

}
//Banana 类
package food;

public class Banana extends Food{

@Override
void taste() {

System.out.println(this.weight);
}
}
@Override
void taste() {
//taste方法打印出Cake的重量
System.out.println(this.weight);
}

}
//测试类
package food;

public class TestFood {
public static void main(String[] args) {
Cake cake=new Cake(4);
Banana banana=new Banana();
cake.taste();//4
banana.taste();//0
}
}
求分

Answer 2

public abstract class Food {
public int weight;
public abstract void taste();
}

public class Cake extends Food {
public Cake(int weight) {
this.weight = weight;
}
@Override
public void taste() {
System.out.println(weight);
}

}

public class Banana extends Food {

@Override
public void taste() {
System.out.println(weight);
}

}

public class TestFood {
public static void main(String[] args) {
Cake cake = new Cake(30);
Banana banana = new Banana();
cake.taste();
banana.taste();
}

}

给个多几个分啊？我做的好辛苦的噢
public abstract class Food {

public void taste() {
}
public String weight="aaa";
}

public class Cake extends Food{

public void Cake(String weight) {
}
public void taste() {
System.out.println(weight);
}

}

public class Banana extends Food{

public String weight="bbbb";
public void taste() {
System.out.println(weight);
}

}

public class TestFood {

public static void main(String[] args) {
Cake cake = new Cake();
Banana banana = new Banana();
cake.taste();
banana.taste();
}
}
