Day 4: Make framework

Software is a big industry. One of its demands is rapid development and extensible capacity. Duplicated or “copy & paste” code seems good in software development, but in fact, it is the cause of many problems for:

- maintain due to order to find & fix every buggy repeated code

- understand because the code is larger

- etc.

As an architect and developer of your fantastic team, you need to figure out a framework of your game. (mark of 3)

Code:
//Moveable

public interface Moveable
{
    void jump();
    void forward();

}


// Actor

public abstract class Actor implements Moveable { private Circle player; public Actor() { player = new Circle(); player.makeVisible(); } public void jump() { player.slowMoveVertical(-100); player.slowMoveVertical(100); } public void forward() { player.slowMoveHorizontal(10); } }

// JumpGoActor

public class JumpGoActor extends Actor { public void jump() { super.player.slowMoveVertical(-3); forward(); } }

// GoJumpActor

public class GoJumpActor extends Actor { public void jump() { forward(); super.player.slowMoveVertical(-3); } }

Make an explanation to your team about the need of this framework, also point out some of this advantages to demonstrate your awareness of the complexity of this framework.

Abstract: Khá giống so với Interface, giúp quản lí các method dễ dàng hơn.

• Có khả năng đặt public/private/protected cho các method
• Có thể thêm/sửa các lệnh trong abstract method
