package simplePhone;
public abstract class Phone {
public abstract void voice();
}

package simplePhone;

public SimplePhone() {
    System.out.println("这是一部简单手机");
}

@Override

}

}

package simplePhone;
public class Changer extends Phone{
private Phone phone;
public Changer(Phone phone) {
this.phone=phone;
}

@Override
public void voice() {
    phone.voice();
}

}

package simplePhone;

    super(phone);
    System.out.println("变成高级手机");
    flash();
}

public void flash() {

    System.out.println("手机增加震动功能");
}

public void voice() {
    super.voice();

}

package simplePhone;

型号抽象类：
public abstract class Size {
public abstract void sizePen();
}
具体型号类：
public class SmallPen extends Size{
//小型
public void sizePen() {
System.out.println("小型");
}
}
public class MiddlePen extends Size{
//中型
public void sizePen() {
System.out.println("中型");
}
}
public class BigPen extends Size{
//大型
public void sizePen() {
System.out.println("大型");
}
}
颜色抽象类：
public abstract class Color {
public abstract void colorPen();
}
具体颜色类：
public class GreenPen extends Color{
public void colorPen() {
System.out.println("绿色");
}
}
public class RedPen extends Color{

public void colorPen() {

System.out.println("红色");

}

}

画笔：
public class Pen {
//画笔
private Size size;
private Color color;
public Size getSize() {
return size;
}
public void setSize(Size size) {
this.size = size;
}
public Color getColor() {
return color;
}
public void setColor(Color color) {
this.color = color;
}
}
聚合画笔：
public class MianClass {
public static void main(String[] args) {
//颜色大小随意组合
Pen pen=new Pen();
//组合小型红色画笔
pen.setSize(new SmallPen());
pen.setColor(new RedPen());
//组合大型绿色画笔
pen.setSize(new BigPen());
pen.setColor(new GreenPen());
}
}
