4,写一个传奇游戏中的猪类，类中有属性：颜色(color)、重量(weight)、攻击力(attack)、准确度(accuracy)。再写一个测试类，生成一个猪的对象，将此猪的颜色值为“白色(white)”，重量为5，攻击力为50点，准确度为0.8。要求输出此猪的信息格式为：一只白色的猪，重量5，攻击为50点血，准确度为0.8，我好怕怕呀

    }

    public void setAttack(int attack) {
        this.attack = attack;
    }

    public double getAccuracy() {
        return accuracy;
    }

    public void setAccuracy(double accuracy) {
        this.accuracy = accuracy;
    }

    public Zhu(String color, int weight, int attack, double accuracy) {
        super();
        this.color = color;
        this.weight = weight;
        this.attack = attack;
        this.accuracy = accuracy;
    }
    
    

}

        System.out.println("一只"+z.getColor()+"的猪，重量"+z.getWeight()+"，攻击为"+z.getAttack()+"点血，准确度为"+z.getAccuracy()+"，我好怕怕呀");

    }

}
