//类适配器public class ClassAdapter {interface Target{public abstract void targetMethod();}class Adaptee{public void adapteeMethod(){System.out.println("adapteeMethod...");}}class Adapter extends Adaptee implements Target{public void targetMethod() { super.adapteeMethod();}}public static void main(String[] args){ClassAdapter ca = new ClassAdapter();Target t = ca.new Adapter();t.targetMethod();}} ?//对象适配器
public class ObjectAdapter {interface Target{public abstract void targetMethod();}class Adaptee{public void adapteeMethod(){System.out.println("adapteeMethod...");}}class Adapter implements Target{private Adaptee adaptee;public Adapter(Adaptee adaptee){this.adaptee = adaptee;}public void targetMethod() {adaptee.adapteeMethod();}}public static void main(String[] args){ObjectAdapter ca = new ObjectAdapter();Adaptee adptee = ca.new Adaptee();Target t = ca.new Adapter(adptee);t.targetMethod();}}??
