请阅读下面的程序,在空白处填写正确的代码,使Son类的eat方法重写Father的eat方法。 public class Father { public void eat(String name){ System.out.println(name+"吃番薯"); } } class Son ______________{ @Override public void eat(String name){ System.out.println(name+"吃米饭"); } }

应该填写 `extends Father`,即:
```
class Son extends Father {
@Override
public void eat(String name){
System.out.println(name+"吃米饭");
}
}
```
这样,Son类就继承了Father类,并重写了其中的eat方法。当调用Son的eat方法时,将输出"某某吃米饭"。

3、阅读下面的程序,在空白处填写正确的代码,使Son类的eat方法重写Father的eat方法。 public class Father{ public void eat(String name){ System.out.println(name+"吃番薯"); } } class Son { public void eat(String name){ System.out.println(name+"吃米饭"); } }
public class Father {
public void eat(String name) {
System.out.println(name + "吃番薯");
}
}
class Son extends Father {
@Override
public void eat(String name) {
System.out.println(name + "吃米饭");
}
}
please give a example about how to implement son class and father class by python
Sure, here is an example of implementing a subclass and superclass (father class) relationship in Python:
class Father:
def __init__(self, name):
self.name = name
class Son(Father):
def __init__(self, name, age):
Father.__init__(self, name)
self.age = age
father = Father("John")
son = Son("David", 20)
print(father.name)
print(son.name)
print(son.age)
In this example, Father is the superclass and Son is the subclass. The Son class inherits from the Father class using the syntax "class Son(Father):", indicating that the Son class is a subclass of the Father class.
The init function of the Son class includes both the "name" parameter from the Father class as well as a new "age" parameter specific to the Son class. It calls the init function of the Father class and passes the "name" parameter using the syntax "Father.__init__(self, name)".
When creating instances of the Father and Son classes, we can see that the Son instance has both the name attribute inherited from the Father class and the age attribute specific to the Son class.
