[实验任务一]:双向适配器
实现一个双向适配器,使得猫可以学狗叫,狗可以学猫抓老鼠。
实验要求:
1. 画出对应的类图;
2.提交源代码;
public interface CatTarget {
public abstract void catchMouse();
}
public class ConcreteCatTarget implements CatTarget {
@Override
public void catchMouse() {
System.out.println("抓老鼠");
}
}
public interface DogAdaptee {
public abstract void cry();
}
public class ConcreteDogAdaptee implements DogAdaptee {
@Override
public void cry() {
System.out.println("汪汪叫");
}
}
public class Adapter implements CatTarget,DogAdaptee {
private CatTarget catTarget;
private DogAdaptee dogAdaptee;
public Adapter() {
}
public void setCatTarget(CatTarget catTarget) {
this.catTarget = catTarget;
}
public void setDogAdaptee(DogAdaptee dogAdaptee) {
this.dogAdaptee = dogAdaptee;
}
public void catchMouse() {
System.out.print("猫学狗叫,即目标类调用适配者中的方法:");
dogAdaptee.cry();
}
public void cry(){
System.out.print("狗学猫抓老鼠,即适配者调用目标类中的方法:");
catTarget.catchMouse();
}
}
public class Client {
public static void main(String[] args) {
//适配器
Adapter adapter = (Adapter) XMLUtils.getBean("adapterPattern");
//目标类通过适配器调用适配者方法
CatTarget concreteCatTarget = (ConcreteCatTarget) XMLUtils.getBean("adapterPatternTarger");
adapter.setCatTarget(concreteCatTarget);
adapter.cry();
//适配者通过适配器调用目标类方法
DogAdaptee concreteDogAdaptee = (ConcreteDogAdaptee) XMLUtils.getBean("adapterPatternAdaptee");
adapter.setDogAdaptee(concreteDogAdaptee);
adapter.catchMouse();
}
}
