class Car
{
    int num;
    String name;
    String color;
    public static void run() {
        System.out.println("行驶中");
    }
}
//再类中定义的变量：成员变量
//在类中定义的函数：成员函数
class Demo1
{
    public static void main(String[] args) {
        //创建一个car对象
        Car benchi = new Car();
        //成员访问符
        benchi.num = 4;
        benchi.color = "白色";
        benchi.name = "奔驰";
        System.out.print(benchi.num+ "量" + benchi.color+"的" + benchi.name);
        benchi.run();
    }
 
}
