物件導向基礎概念 (一)

定義一 Car 類別，並在 Car 類別下建立三個實體物件，分別為 bus、truck 與 taxi。

執行參考畫面如下：

public class Ch56{
public static void main(String args[])
{
Car bus=new Car(); //在Car類別下新增一個名為bus的物件, 該物件尚未初始化
bus.name="公車"; //對bus進行初始化
bus.wheel=6;
bus.load=40;
Car truck=new Car();
truck.name="卡車";
truck.wheel=8;
truck.load=3;
Car taxi=new Car();
taxi.name="計程車";
taxi.wheel=4;
taxi.load=5;
System.out.println(bus.name+"有"+bus.wheel+"個輪子,可載"+bus.load+"人.");
System.out.println(truck.name+"有"+truck.wheel+"個輪子,可載"+truck.load+"人.");
System.out.println(taxi.name+"有"+taxi.wheel+"個輪子,可載"+taxi.load+"人.");
}
}
class Car //自訂類別
{
String name; //宣告該類別擁有哪些屬性
int wheel;
int load;
//建構子 (尚未定義)
//方法 (尚未定義)
}
