创建一个animal类

有这样类似的代码嘛，有点疑惑，不是很会做这个。大概是什么样子的呢？

public class Animal {

    private Integer weight;

    private String color;

    /**
     * 无参构造方法
     */
    public Animal() {
    }

    /**
     * 全参构造方法
     * @param weight
     * @param color
     */
    public Animal(Integer weight, String color) {
        this.weight = weight;
        this.color = color;
    }

    public Integer getWeight() {
        return weight;
    }

    public void setWeight(Integer weight) {
        this.weight = weight;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }
}

public class Bird extends Animal{

    /**
     * 无参构造方法
     */
    public Bird() {
    }

    /**
     * 全参构造方法
     *
     * @param weight
     * @param color
     */
    public Bird(Integer weight, String color) {
        super(weight, color);
    }

    public void fly(){
        System.out.println("fly");
    }

    public static void main(String[] args) {
        Bird bird = new Bird(10, "white");
        bird.fly();
    }
}

创建类，添加属性，然后加几个方法，再创建类继承一下
