JAVA基础五——面向对象一

代码示例：

package day4;public class Oop1 {public static void main(String[] args) {//Car car=new Car("丰田车","白色",4);Car car=new Car();car.type();}}class Car{String name;String color;int lun;//public Car(String name, String color, int lun) {//this.name = name;//this.color = color;//this.lun = lun;//}public Car(){this.name="马自达";this.color="红色";this.lun=4;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getColor() {return color;}public void setColor(String color) {this.color = color;}public int getLun() {return lun;}public void setLun(int lun) {this.lun = lun;}public void type(){System.out.println("一辆"+color+name+"有"+lun+"个轮子");}}
