多态的设计模式-----用多态体现面向对象

要执行：“司机开车去贵阳” 

用交通工具类（Vehicle）来封装下面的三个对象 

有三个对象：Driver,Car,Address 

Driver的代码： 

package com.yang.study; 

public class Driver { 
private String name; 

public String getName() { 
return name; 
} 

public void setName(String name) { 
this.name = name; 
} 

public void driving(Vehicle c,Address add){ 
c.go(Driver.this,add); 
} 
} 


Car的代码： 

package com.yang.study; 

public class Car extends Vehicle { 


@Override 
public void go(Driver driver, Address address) { 
System.out.println(driver.getName()+":开车去"+address.getName()); 

} 

} 



Address的代码： 

package com.yang.study; 

public class Address { 
private String name ; 
public Address() { 

} 
public Address(String name) { 
this.name = name; 
} 

public String getName() { 
return name; 
} 

public void setName(String name) { 
this.name = name; 
} 

} 


Vehicle的代码：用所有的车去继承交通工具类（可扩展性） 

package com.yang.study; 

public abstract class Vehicle { 

public abstract void go(Driver driver,Address address); 

} 


Test的测试代码： 

package com.yang.study; 

public class Test { 

/** 
* @param args 
*/ 
public static void main(String[] args) { 
Driver driver = new Driver(); 
driver.setName("夏文权"); 
   Address address = new Address(); 
   address.setName("贵阳"); 

driver.driving(new Car(), address); 

} 

}
