桥接模式

桥接模式：将抽象部分与它的实现部分分离，使它们都可以独立地变化。以下是例子：

 

public class Jacket extends Clothing{

public void personDressCloth(Person person) {

System.out.println(person.getType()+"穿马甲"); } }

public class Trouser extends Clothing{

public void personDressCloth(Person person) {

System.out.println(person.getType()+"穿裤子");}}

 

public abstract class Person {

private Clothing clothing;

private String type;

public Clothing getClothing(){

return clothing;

}

public void setType(String type){

this.type = type;

}

public String getType(){

return this.type;

}

public abstract void dress();

}

 

public class Lady extends Person{  

public Lady(){

setType("女人"); }

public void dress() {

Clothing clothing = getClothing();

clothing.personDressCloth(this); } }

 

public class Man extends Person{  

public Man(){

setType("男人"); }

public void dress() {

Clothing clothing = getClothing();

clothing.personDressCloth(this); } }

 

 public class Test {

/**

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

Person man = new Man();

Person lady = new Lady();

Clothing jacket = new Jacket();

Clothing trouser = new Trouser();

jacket.personDressCloth(man);

trouser.personDressCloth(man);

jacket.personDressCloth(lady);

trouser.personDressCloth(lady);

}

}
