（二十四）面向對象

class Car
{int num;String name;String color;public static void run() {System.out.println("行駛中");}
}
//再類中定義的變量：成員變量
//在類中定義的函數：成員函數
class Demo1
{public static void main(String[] args) {//創建一個car對象Car benchi = new Car();//成員訪問符benchi.num = 4;benchi.color = "白色";benchi.name = "奔馳";System.out.print(benchi.num+ "量" + benchi.color+"的" + benchi.name);benchi.run();}}
