class 類別基本理論

class 是個很抽象的東西，可以把它當成是"設計圖"。
用人來比喻，一點一點的建構出來：
先不考慮公有(public)與私有(private)

我們定義一個人
**(類別)
public class People{
}

Abstract Class(抽像類別)，Interface(介面or接口)

Abstract Class(抽像類別)：
----------------------------------------------------------------------------------------
[1]...顧名思義因為是抽象，所以無法產生(new)物件
abstract class AbClass{
	-- aaa() 是有明確定義的方法
	void aaa(){
		// method here
	}
