父类

package Zuoye;

public class Car {
    
    
    
    
    private String name;
    private String color;
    private int price;
    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 getPrice() {
        return price;
    }
    public void setPrice(int price) {
        this.price = price;
    }
    
    public Car(String name,String color,int price)
    {
        System.out.println("车的构造方法");
        this.name =name;
        this.color=color;
        this.price=price;
    }
    
    public void run()
    {
        System.out.println("我可以跑");
    }
    
    public void xiaohao()
    {
        System.out.println("我能消耗油");
    }
    
    
    
    
    

}

 

子类

package Zuoye;

public class Carddezilei extends Car{

    public Carddezilei()
    {
        super("法拉利", "红色", 1000);
        System.out.println("车的子类的构造方法");
    }
    
    public void run()
    {
        System.out.println("我可以跑的很快");
    }
    
    public void zaizhong()
    {
        System.out.println("我不能载重");
    }
    
    

}

 

测试类

package Zuoye;

public class Cardeceshi {

    public static void main(String[] args) {
        Car c1=new Car("奇瑞", "红色", 1);
        System.out.println("我是"+c1.getName()+",颜色是"+c1.getColor()+",售价是"+c1.getPrice()+"万元");
        c1.run();
        c1.xiaohao();
        System.out.println();
        
        Carddezilei c2=new Carddezilei();
        System.out.println("我是"+c2.getName()+"，颜色是"+c2.getColor()+"，售价"+c2.getPrice()+"万元");
        c2.run();
        c2.zaizhong();
        c2.xiaohao();
        System.out.println();
        
        Car c3=new Carddezilei();
        System.out.println("我是"+c3.getName()+"，颜色是"+c3.getColor()+",售价"+c3.getPrice());
        c3.run();
        c3.xiaohao();
        
    }
