[Java知识库]黑马JAVA P70 面向对象语法：构造器（理解、且面试会考）

?

package com.itheima.constructor;

public class Test {
    public static void main(String[] args) {
        Car c = new Car();
        System.out.println(c.name);
        System.out.println(c.price);

        Car c2 = new Car("宝马",80);
        System.out.println(c.name);
        System.out.println(c.price);
    }
}

?

package com.itheima.constructor;

public class Car {
    String name;
    double price;
    //无参数构造器
    public Car(){
        System.out.println("无参数构造器被触发执行~~~");
    }

    //有参数构造器
    public Car(String n,double p){
        System.out.println("有参数构造器被触发执行~~~");
        name = n;
        price = p;
    }
}
