1. Abstract Factory..

2. Builder

3. Factory Method..

4. Prototype..

5. Singleton.

结构型模式...

1. Adapter.

2. Bridge..

3. Composite..

4. Decorator.

5. Facade..

静态代理：

public class Tank implements Movable {

    /**
     * 模拟坦克移动了一段儿时间
     */
    @Override
    public void move() {
        System.out.println("Tank moving claclacla...");
        try {
            Thread.sleep(new Random().nextInt(10000));
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
class TankTimeProxy implements Movable {
    Movable m;

    public TankTimeProxy(Movable m) {
        this.m = m;
    }

    @Override
    public void move() {
        long start = System.currentTimeMillis();
        m.move();
        long end = System.currentTimeMillis();
        System.out.println(end - start);
    }
}

class TankLogProxy implements Movable {
    Movable m;

    public TankLogProxy(Movable m) {
        this.m = m;
    }

    @Override
    public void move() {
        System.out.println("start moving...");
        m.move();
        long end = System.currentTimeMillis();
        System.out.println("stopped!");
    }
}

interface Movable {
    void move();
}

使用时

        new TankLogProxy(
                new TankTimeProxy(
                        new Tank()
                )
        ).move();

6. Memento..

7. Observer

8. State..
