将抽象部分与它的实现部分分离，使独立。
抽象和抽象直接连起来，然后实现抽象类的其他函数，那么这两个类就连起来了。
abstract class Person{
private Clothing clothing;
private String type;
public Clothing getClothing() {
return clothing;
}
public void setClothing(Clothing clothing) {
this.clothing = clothing;
}
public void setType(String type) {
this.type = type;
}
public String getType() {
return type;
}
public abstract void dress();
}
class Man extends Person{
public Man(){
setType("man");
}
public void dress(){
Clothing clothing =getClothing();
clothing.personDressCloth(this);
}
}
class Lady extends Person{
public Lady(){
setType("lady");
}
public void dress(){
Clothing clothing =getClothing();
clothing.personDressCloth(this);
}
}
abstract class Clothing{
public abstract void personDressCloth(Person person);
}
class Jacket extends Clothing{
@Override
public void personDressCloth(Person person) {
System.out.println(person.getType()+"jacket");
}
}
class Trouser extends Clothing{
@Override
public void personDressCloth(Person person) {
System.out.println(person.getType()+"trouser");
}
}
public class BridgeTest {
public static void main(String[] args){
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);
}
}
