浅谈java多态的实现主要体现在哪些方面

<span style="font-size:14px;"> 

例：
public class Address {
private String name;
public Address(String name){
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

定义基类(抽象类)：
public abstract class Vehicle {
abstract void go(Address address);
}

Car对于基类的实现：
public class Car extends Vehicle{
@Override
public void go(Address address){
System.out.println("Car to " + address.getName());
}
}

Plane对于基类的实现：
public class Plane extends Vehicle{
@Override
void go(Address address) {
System.out.println("Plane to " + address.getName());
}
}


Driver中多态：
public void drive(Vehicle v){ ///多态，父类引用指向子类对象，实际传过来的是抽象类Vehicle的子类，或者实现类，然后编译器会根据具体实现类，来找实现方法。
v.go(new Address("杭州(abstract)")); ///此方法在具体的实现中被重写
}

Test:
public static void main(String[] args) {
Driver d = new Driver();
d.drive(new Plane()); //实际是Plane对象，则编译器就会找到Plane中，对go的实现
d.drive(new Car()); //实际是Car对象，则编译器就会找到Plane中，对go的实现
}

输出结果：
Plane to 杭州(abstract)
Car to 杭州(abstract)
